=Biography=
Born in ], ], Rushton's father was a building contractor, while his mother was ] and gave him his middle name. Rushton was raised in South Africa during the reign of white-dominance and ]. Rushton received a ] in psychology from ] at the ] in 1970 and in 1973 received his ] from the ] for his work on altruism in children. He then moved to the ] where he continued his work until 1974.


==Early life and education==
Rushton taught at ] in ] from 1974-1976 and the ] until 1977. He then moved to the University of Western Ontario, and was made a full professor there in 1985. He received his ] from London in 1992.
Rushton was born in ], England. During his childhood, he emigrated with his family to South Africa, where he lived from age four to eight (1948–1952). His father was a building contractor and his mother came from France. The family moved to Canada, where Rushton spent most of his teen years. He returned to England for university,<ref name=globeobit/> receiving a B.Sc. in psychology from ] at the ] in 1970, and, in 1973, his Ph.D. in ] from the ] for work on ] in children. He continued his work at the ] until 1974.<ref>{{cite web | url=http://rushton.socialpsychology.org/ | title=J. Philippe Rushton | work=] | access-date=16 May 2017}}</ref>


==Later life and career==
Rushton has published more than 100 papers and articles, written a number of books, including a pair on altruism, one on 'scientific excellence', and a psychology text (co-authored). In 1988 he was awarded a ]. Following his work on behavioral genetics and sociobiology Rushton began studying racial differences.
Rushton taught at ] in Canada from 1974 to 1976 and the ] until 1977. He moved to the ] and was made full professor (with tenure) in 1985.

=Specific works=
==Genetic similarity hypothesis==
Rushton began his career with studies on ]. He has hypothesized a heritable component in altruism and is the creator of the , which states that individuals tend to be more altruistic to individuals who are genetically similar to themselves, and less altruistic, and sometimes outwardly hostile to individuals who are less genetically similar. Rushton describes "ethnic conflict and rivalry" as "one of the great themes of historical and contemporary society" and suggests that it may have its roots in the evolutionary impact of individual from groups "giving preferential treatment to genetically similar others". Rushton argues that "the makeup of a gene pool causally affects the probability of any particular ideology being adopted". Foreshadowing the massive controversy that would erupt over his later racial theories, Rushton writes "religious, political, and other ideological battles may become as heated as they do because they have implications for genetic fitness".


Rushton died of cancer on October 2, 2012, at the age of 68.<ref>{{Cite web | url=http://www.yourlifemoments.ca/sitepages/obituary.asp?oid=644735 | title=John Philippe Rushton - Obituaries - London, ON - Your Life Moments}}</ref><ref name=globeobit>{{cite news | last = Allemang | first = John
===Critiques===
| title = Philippe Rushton, professor who pushed limits with race studies, dead at 68
In order for Rushton's theory to be plausible, one must believe that individuals can discern genetic similarities and differences. Population geneticists, such as ], have found that genetic differences within superficially identifiable groups (various "races") are in fact of much greater magnitude than genetic differences between such groups. This challenges Rushton's hypothesis by denying him a mechanism by which individuals can accurately determine who is more and who is less genetically similar.

==Work and opinions==
Rushton supporters claim that when ] is performed on data from ], major racial groups did indeed form widely seperated clusters{{fact}}. This discernment of clusters does not directly address the relative magnitude of genetic differences between groups versus within groups, but is asserted to validate their belief in a biological basis for race.


===Genetic similarity theory===
His hypothesis is also challenged by counter examples indicating hostility between genetically similar groups, and peace between genetically different groups. A critique by John Tooby & Leda Cosmides stated, "For example, immigrants originally from neighboring villages in Italy were prevented from working together because of the serious violence that would erupt; yet these same individuals lived peacefully among Chinese immigrants (Sowell 1981)."<ref> by John Tooby & Leda Cosmides (1989). Behavioral and Brain Sciences 12, 542-544.</ref>
Early in his career, Rushton did research on ]. He theorized a heritable component in altruism and developed ''Genetic Similarity Theory'', which is an extension of ]'s theory of ]. It holds that individuals tend to be more altruistic to individuals who are genetically similar to themselves even if they are not kin, and less altruistic, and sometimes outwardly hostile, to individuals who are less genetically similar. Rushton describes "ethnic conflict and rivalry" as "one of the great themes of historical and contemporary society", and suggests that this may have its roots in the evolutionary impact on individuals from groups "giving preferential treatment to genetically similar others". According to Rushton: "the makeup of a gene pool causally affects the probability of any particular ideology being adopted".


Articles in a 1989 issue of '']'' criticized the theory.

"Green beard theory", ''Behavioral and Brain Sciences'' (1989) 12:3 p. 528</ref> John Hartung criticized Rushton for failing to conduct an adequate ] study and for ignoring contradictory evidence.<ref>{{cite journal | last1 = Hartung | first1 = John | year = 1989 | title = Testing genetic similarity: Out of control | journal = Behavioral and Brain Sciences | volume = 12 | issue = 3| page = 529 | doi=10.1017/s0140525x00057460| s2cid = 144642600 }}</ref>

In a 2020 statement, his former department at the University of Western Ontario stated: "Rushton's works linking race and intelligence are based on an incorrect assumption that fuels systemic racism, the notion that racialized groups are concordant with patterns of human ancestry and genetic population structure."<ref name=":0" /> Furthermore, they stated that Rushton's work on the topic is "characterized by a complete misunderstanding of population genetic measures, including fundamental misconceptions about the nature of heritability."<ref name=":0" />

===Application of ''r''/''K'' selection theory to race===
Rushton wrote the book ''Race, Evolution And Behavior: A Life History Perspective''<ref>{{cite book
{{main|Differential K theory|l1=Differential ''K'' theory}}
| author = Rushton, J. P.
Rushton's book '']'' (1995) attempted to use ] to explain what he described as an evolutionary scale of characteristics indicative of nurturing behavior in which ] consistently averaged high, ] low, and ] in the middle. He first published this theory in 1984. Rushton argued that East Asians and their descendants average a larger brain size, greater intelligence, more sexual restraint, slower rates of maturation, and greater law abidingness and social organization than do Europeans and their descendants, whom he argued average higher scores on these measures than Africans and their descendants. He hypothesized that ''r''/''K'' selection theory explains these differences.

Rushton claims that there are three main "races" of human-kind, ] (i.e. Orientals), ] (i.e. whites), and ] (i.e. blacks). He further asserts that these group fall persistently and repeatedly into the same one-two-three pattern when compared on a list of 60 different behavioral and anatomical variables. Rushton uses averages of hundreds of studies, modern and historical, to assert the existence of this pattern.


Rushton's application of ''r''/''K'' selection theory to explain differences among racial groups has been widely criticized. Differential K theory in particular was described in a 2020 statement by Rushton's former department at Western Ontario University as "thoroughly debunked."<ref name=":0" />
The book grew out of his earlier paper, ''Evolutionary Biology and Heritable Traits (With Reference to Oriental<ref>Rushton has sometimes been criticized for using the word "Oriental", when most North Americans use the term "Asian" instead. Since the 1990s, Asian American activists have begun campaigns to stop people from using the word Oriental, claiming the term has offensive connotations. However, the term is widely used non-pejoratively in Great Britain to denote people of Chinese, Japanese, or Korean ancestry, since the term "Asian" there has historically referred to people from the ].</ref>-White-Black Difference)'', which was presented at the Symposium on Evolutionary Theory, Economics and Political Science, AAAS Annual Meeting (San Francisco, CA, ], ]).


One of his many critics is the ] ], who has done extensive testing of the ''r''/''K'' selection theory with species of ] flies. Graves argues that not only is ''r''/''K'' selection theory considered to be virtually useless when applied to human life history evolution, but Rushton does not apply the theory correctly, and displays a lack of understanding of evolutionary theory in general.<ref>{{cite journal | last=Graves | first=J.

Other scholars have argued against Rushton's hypothesis on the basis that the concept of ] is not supported by genetic evidence about the diversity of human populations, and that his research was based on ].<ref>{{cite journal | last1 = Sternberg | first1 = Robert J. | last2 = Grigorenko | first2 = Elena L. | last3 = Kidd | first3 = Kenneth K. | year = 2005 | title = Race, and Genetics | journal = American Psychologist | volume = 60 | issue = 1 | pages = 46–59 | doi = 10.1037/0003-066X.60.1.46 | pmid = 15641921 | citeseerx = 10.1.1.174.313 }}</ref>
The book claims that Mongoloids, on average, are at one end of a continuum, that Negroids, on average, are at the opposite end of that continuum, and that Caucasoids rank in between Mongoloids and Negroids, but closer to Mongoloids. His continuum includes both external physical characteristics and personality traits.


Later studies by Rushton and other researchers have argued that there is empirical support for the theory,<ref>{{Cite journal| doi = 10.1016/j.intell.2007.04.001| title = Temperature and evolutionary novelty as forces behind the evolution of general intelligence☆| year = 2008| last1 = Kanazawa | first1 = S.| journal = Intelligence| volume = 36| issue = 2| pages = 99–108}}</ref><ref>{{Cite journal | last = Templer | first = Donald I. | author-link = Donald Templer | title = Correlational and factor analytic support for Rushton's differential ''K'' life history theory | doi = 10.1016/j.paid.2008.05.010 | journal = Personality and Individual Differences | volume = 45 | issue = 6 | pages = 440–444 | year = 2008 }}</ref><ref>{{Cite journal | doi = 10.1016/j.jrp.2008.03.002 | last1 = Rushton | first1 = J. | last2 = Bons | first2 = T. | last3 = Hur | first3 = Y. | title = The genetics and evolution of the general factor of personality | journal = Journal of Research in Personality | volume = 42 | issue = 5 | pages = 1173–1185 | year = 2008 | citeseerx = 10.1.1.623.9800}}</ref> though these studies too have been criticized.<ref>{{Cite journal|last1=Wicherts|first1=Jelte M.|last2=Borsboom|first2=Denny|last3=Dolan|first3=Conor V.|title=Why national IQs do not support evolutionary theories of intelligence|journal=Personality and Individual Differences|volume=48|issue=2|pages=91–96|doi=10.1016/j.paid.2009.05.028|year=2010}}</ref>
Citing genetic research by ], the ] hypothesis, and the ] theory, Rushton concludes that Negroids branched off first (200,000 years ago), arguing that throughout all of evolution, more ancient forms of life (i.e. plants, bacteria, reptiles) are less evolved than more recent forms of life (i.e. mammals, primates, humans) and that the much smaller variation in the races is consistent with this trend. "One theoretical possibility," said Rushton "is that evolution is progressive and that some populations are more advanced than others" Rushton has claimed that this first, second, and third chronological sequence perfectly correlates with, and is responsible for, what he believes to be a consistent global multi-dimensional racial pattern on everything from worldwide crime statistics, the global distribution of AIDS, to personality.


Psychologist ] observed that ''r''- and ''K''-selection may have some validity when considering the so-called ], whereby economic development characteristically leads to reduced family size and other ''K'' traits. "But this is a pan-human phenomenon, a flexible, adaptive response to changed environmental conditions&nbsp;...

===Dimensional structure of personality===
Rushton believes that if his model proves to be accurate, then two important predictions can be made about the course of world history. He expects Mongoloid populations could be expected to outdistance the predominantly Caucasoid populations of the Western world, and second, Negroid populations, given their alleged statistical bent toward promiscuity and social chaos, were especially at risk for AIDS.
Beginning in 2008, Rushton researched the structure of ]. Over about a dozen papers, he argued that variation in personality can be explained by variation in a single underlying "general ]," similar to the ] of psychometrics.<ref>{{cite journal | last1 = Lynn | first1 = R | year = 2013 | title = Obituary: John Philippe Rushton, 1943-2012 | journal = Intelligence | volume = 41 | issue = 1| pages = 88–89 | doi=10.1016/j.intell.2012.10.005| doi-access = free }}</ref>


===Opinions===
Rushton believes that his collection of 60 different variables can be unified by a single evolutionary dimension known as the r and K scale. His theory is based on an attempt to apply the inter-species ] to the immensely smaller inter-racial differences within the human species. While all humans display extremely ] behavior, Rushton believes the "races" vary in the degree to which they exhibit that behavior. He asserts that Negroids use a strategy more toward an ] strategy (produce more offspring, but provide less care for them) while Mongoloids use the K strategy most (produce fewer offspring but provide more care for them), with Caucasoids exhibiting intermediate tendencies in this area. He further asserts that Caucasoids evolved more toward a K-selected breeding strategy than Negroids because of the harsher and colder weather encountered in Europe, while the same held true to a greater extent for Mongoloids. Rushton believes that the survival challenges of making warm clothes, building durable shelter, preserving food, and strategically hunting large animals all selected genes for greater intelligence and social organization among the populations that migrated to cold climates.
In 2009 Rushton spoke at the ''Preserving Western Civilization'' conference in Baltimore. It was organized by ] for the stated purpose of "addressing the need" to defend "America's ] heritage and European identity" from immigrants, Muslims, and African Americans. The ] described the conference attendees as "racist academics, conservative ]s and anti-immigrant activists".<ref> {{webarchive|url=https://web.archive.org/web/20091106095039/http://www.adl.org/main_Extremism/PWC_Conference-update.htm |date=2009-11-06 }}, ADL, February 13, 2009</ref>


==Reception==
Although Rushton acknowledges socio-economic and cultural factors, he believes they are more likely to be the product than the cause of a lot of the differences he describes. He asserts for example, "that many African-American youth have adopted a culture of anti-intellectualism", implying that their decisions about culture are based on their IQ, which he sees as based on their race.


===Press coverage===
While Rushton acknowledges alternative interpretations, he believes that his collection of world-wide data is best explained by his r-k theory. While Rushton agrees that contemporary social and economic trends obviously confound the data he describes within any particular time and place (i.e. 20th century America), he believes that such contradictions to his interpretations do not substantially effect his assertions of behavioral consistency of the "races" all over the world, and throughout the course of world history, along with alleged anatomical analogues like brain weight and penis size as evidence of an ancient gene mediated evolutionary hierarchy.
Rushton prompted controversy for years, attracting coverage from the press as well as comments and criticism by scientists of his books and journal articles.


First-year psychology students who took Rushton's classes said that he had conducted a survey of students' sexual habits in 1988, asking "such questions as how large their penises are, how many sex partners they have had, and how far they can ejaculate".<ref name="NYB-3-23-95">], , '']'', Vol. 42, Number 5, March 23, 1995</ref> First-year psychology students at the ] are required "to participate in approved surveys as a condition of their studies. If they choose not to, they must write one research paper. Also, many students feel subtle pressure to participate in order not to offend professors who may later be grading their work. However, if a study is not approved, these requirements do not apply at all."<ref name="NYB-3-23-95"/> For his failing to tell students they had the option not to participate in his studies without incurring additional work, the university barred Rushton for two years from using students as research subjects. He had tenure at UWO.<ref name="NYB-3-23-95"/>
===Critiques===

Ottawa: Oct 1, 2005. pg. A.1.</ref> In the same article, Rushton suggested that equalizing outcomes across groups was "impossible". The ] called the piece "yet another attack" by Rushton, and it criticized those who published his work and that of other "race scientists".<ref name="splcenter.org">, Southern Poverty Law Center</ref>
Rushton claims to use a methodology he calls the "aggregation" of evidence, in which he averages hundreds of studies, modern and historical, with equal weight to demonstrate the patterns he asserts. He claims that by averaging many studies, which may include those that used poor research methods, the results one gets can be very accurate. He claims that measurement error typically cancels out when multiple studies are averaged, and asserts that his approach is less biased than the work of researchers who selectively pick and choose from the world-wide literature based on critical analysis.


===Academic opinion===
A number of prominent scientists however dismiss his methodology, including biologist Douglas Wahlsten, who in a review of Rushton's book wrote:
====Favorable====
In a 1991 work, the ] ] ] (one of the two co-founders of the ''r''/''K'' selection theory which Rushton uses) was quoted as having said about him:<ref>from Knudtson P.

Three years after the publication of Wilson's 1975 book '']'', Rushton had already begun a long correspondence with Wilson. The letters became particularly extensive between 1987 and 1995 (Wilson's letters have now been archived by the ]). After Wilson's death at the end of 2021, historians of science Mark Borrello and ] have reassessed how Wilson's thinking on issues of race and evolution was influenced by Rushton.<ref>{{cite web|last1=Borrello|first1=Mark|last2=Sepkoski|first2=David|author2-link=David Sepkoski|title=Ideology as Biology|work=]|date=5 February 2022|url=https://www.nybooks.com/daily/2022/02/05/ideology-as-biology/|access-date=8 February 2022}} (registration required)</ref><ref>{{cite web|title="The Last Refuge of Scoundrels": New Evidence of E.

In a 1995 review of Rushton's ''Race, Evolution, and Behavior'', anthropologist and population geneticist ] expressed doubt as to whether all of Rushton's data fit the ''r''/''K'' model he proposed, but nonetheless praised the book for its proposing of a theoretical model that makes testable predictions about differences between human groups. He concludes that "Perhaps there will ultimately be some serious contribution from the traditional smoke-and-mirrors social science treatment of IQ, but for now Rushton's framework is essentially the only game in town."<ref>Harpending, Henry. {{webarchive|url=https://web.archive.org/web/20110817172506/http://harpending.humanevo.utah.edu/Documents/iq.pdf |date=2011-08-17 }}, 1995.</ref> In their 2009 book '']'', Harpending and ] later described Rushton as one of the researchers to whom they are indebted.<ref>Cochran, Gregory and Herny Harpending (2009).

<blockquote>''averaging does no thing to reduce bias in sampling and measurement, and such flaws are abundant in the cited literature. For example, among the 38 reports on brain weight, all but two gave figures for only one group, with most cases being people living in the nation of their ancestors, such as an article on Japanese living in Japan and another on Kenyans living in Kenya.

The Hamilton (Ontario) Spectator, April 17, 2000.</ref>
David P. Barash also harshly criticises the 'principle of aggregation' in his review:


Some criminologists who study the relationship between race and crime regard Rushton's ''r''/''K'' theory as one of several possible explanations for racial disparities in crime rates.<ref>Goodison, Sean (2009), "''r''/''K'' Theory", in Gabbidon, Shaun L.; Greene, Helen T. (Eds.), ''Encyclopedia of Race and Crime''. Thousand Oaks: Sage Publications, pp. 713–716. {{ISBN|978-1-4129-5085-5}}.</ref> Others, such as the criminologist ], think that Rushton has developed one of the more controversial biosocial theories related to race and crime; he says that it has been criticized for failing to explain all of the data and for its potential to support racist ideologies.<ref>Gabbidon, Shaun L. (2010). ''Criminological Perspectives on Race and Crime, 2nd ed.''. New York: Routledge, pp. 41-44. {{ISBN|978-0-415-87424-3}}.</ref> The criminologist ] has defended Rushton, claiming that none of Rushton's critics has supplied data indicating anything other than the racial gradient he identifies, and that it is unscientific to dismiss Rushton's ideas on the basis of their political implications.<ref>Walsh, Anthony (2004). ''Race and Crime: A Biosocial Analysis''. Hauppauge, New York: Nova Science Publishers, pp. 15-17. {{ISBN|978-1-59033-970-1}}.</ref>
<blockquote>''...Rushton argues at length for what he calls the 'principle of aggregation', which in his hands, means the pious hope that by combining numerous little turds of variously tainted data, one can obtain a valuable result; but in fact, the outcome is merely a larger than average pile of shit''</blockquote>


====Unfavorable====
Wahlsten also further criticizes Rushton's particular use of data in the same book review:
On 22 June 2020, the Department of Psychology at the University of Western Ontario issued a statement regarding their former faculty member, which read in part:<ref name=":0" />
{{blockquote|Despite its deeply flawed assumptions and methodologies, Rushton's work and other so-called "race science" (currently under the pseudonym of "race realism") continues to be misused by white supremacists and promoted by eugenic organizations. Thus, Rushton's legacy shows that the impact of flawed science lingers on, even after qualified scholars have condemned its scientific integrity. Academic freedom and freedom of expression are critical to free scientific inquiry. However, the notion of academic freedom is disrespected and abused when it is used to promote the dissemination of racist and discriminatory concepts. Scientists have an obligation to society to speak loudly and actively in opposition of such abuse.}}


Also in 2020, ] summarized Rushton's scholarly reception as follows: "Rushton's work was heavily criticized by psychologists, evolutionary biologists, anthropologists, and geneticists for severe scientific inadequacies, fundamental errors, inappropriate conceptualization of race, inappropriate statistical comparisons, misuse of sources, and serious logical errors and flaws."<ref name=":12">{{Cite web |last=Winston |first=Andrew S. |date=29 May 2020 |title=Scientific Racism and North American Psychology |url=https://oxfordre.com/psychology/view/10.1093/acrefore/9780190236557.001.0001/acrefore-9780190236557-e-516; |website=Oxford Research Encyclopedias: Psychology|doi=10.1093/acrefore/9780190236557.013.516 |isbn=978-0-19-023655-7 }}</ref>
<blockquote>''The author is an earnest believer in genetically determined race differences, and he vows to cling tenaciously to his world view unless his opponents can provide conclusive proof to the contrary. In my opinion, this is the kind of approach to be expected from religious zealots and politicians, not professional scientists. A rigorous evaluation of the evidence cited by Rushton reveals the methods in most studies were seriously flawed and render the data inconclusive. If the evidence is so poor, the proper action for a scientist is to suspend judgment. In reality, there is not one properly controlled study of brain size comparing representative samples of races in the entire world literature.''<ref></ref></blockquote>


In 1989, geneticist and media personality ] criticized Rushton's racial theories in a live televised debate at the ].<ref>{{cite web |url=http://www.cbc.ca/archives/categories/arts-entertainment/media/david-suzuki-scientist-activist-broadcaster-1/the-rushton-suzuki-debate.html |title=The Rushton-Suzuki debate |author=CBC News |date=1989-02-08 |work=] |publisher=Queen in Right of Canada |access-date=2009-11-02|author-link=CBC News }}</ref> He said: "There will always be Rushtons in science, and we must always be prepared to root them out". At the same occasion, Rushton rejected believing in racial superiority, saying "we've got to realize that each of these populations is perfectly, beautifully adapted to their own ancestral environments".<ref>Peter Knudtson, ''A Mirror to Nature'', pg 187</ref>
As Wahlsten points out, Rushton's only defense of his methodology is challenging his critics to explain how his averaging all the studies in the world-wide literature, regardless of critical analysis, has produced a pattern on such a diverse collection of variables with Negroids and Mongoloids falling so persistently at opposite extremes and Caucasoids ''always'' in the middle. Given the consistency of his findings, and the parsimonious explanation he provides, Rushton dismisses any critical analysis of the data he has used, and instead suggests that the onus is on his critics to gather new data using modern techniques. Rushton has stated, "Identifying potential problems in particular studies should lead to calls for additional research, not trenchant acceptance of the null hypothesis. Deconstructing data has lead to erroneous dismissal of fascinating brain-behavior relationships for six decades."


Also in 1989, ] published a paper in the '']'' criticizing a study by Rushton & Bogaert that had been published in the same journal two years earlier. Lynn cited four reasons he considered Rushton & Bogaert's study to be flawed: {{blockquote|First, they did not explain why natural selection would have favored different reproductive strategies for different races. Second, their data on race differences are of questionable validity because their literature review was selective and their original analyses were based on self-reports. Third, they provided no evidence that these race differences had significant effects on reproduction or that sexual restraint is a ''K'' characteristic. Finally, they did not adequately rule out environmental explanations for their data.<ref>{{cite journal|last=Lynn|first=Michael|author-link=Michael Lynn|title=Race differences in sexual behavior: A critique of Rushton and Bogaert's evolutionary hypothesis|journal=]|date=March 1989|volume=23|issue=1|pages=1–6|doi=10.1016/0092-6566(89)90029-9|url=https://scholarship.sha.cornell.edu/cgi/viewcontent.cgi?article=1326&context=articles|hdl=1813/72077|hdl-access=free}}</ref>}}
In a 1996 review of the book, anthropologist ] wrote that "''Race, Evolution, and Behavior'' is an amalgamation of bad biology and inexcusable anthropology. It is not science but advocacy, and advocacy of ']'" (Brace 1996). Brace argues that Rushton assumes the existence of three biological races with no evidence except Rushton's speculation as to what an extraterrestrial visitor to Earth would think. Brace also disagrees with Rushton applying the concept of heritability (normally applied in the context of individuals) to groups. Finally, Brace claims Rushton makes unsupported claims about sub-Saharan African societies.


], psychology professor of the ], criticized Rushton's research on methodological grounds, observing that more variation exists in personality traits within racial groups than between them<ref>{{cite journal|last=Zuckerman|first=Marvin|author-link=Marvin Zuckerman|title=Some dubious premises in research and theory on racial differences: Scientific, social, and ethical issues.|journal=American Psychologist|date=1990|volume=45|issue=12|pages=1297–1303|doi=10.1037/0003-066X.45.12.1297|pmid=2285179 }}</ref> and arguing that Rushton selectively cited data from the ].<ref>{{cite journal|last1=Zuckerman|first1=Marvin|author-link1=Marvin Zuckerman|last2=Brody|first2=Nathan|title=Oysters, rabbits and people: A critique of "race differences in behaviour" by J.P.

Other critics have also charged that his interpretations, conclusions and methods are "sloppy" and "unscientific"<ref></ref>.


] ] argued that Rushton's "substantial success and influence in the discipline" and use of "accepted usage of empirical mainstream methods" pointed to broader problems in academic psychology.<ref>{{cite journal |last1=Teo |first1=Thomas |author-link1=Thomas Teo |title=Empirical Race Psychology and the Hermeneutics of Epistemological Violence |journal=Human Studies |date=Fall 2011 |volume=34 |issue=3 |pages=237–255 |jstor=41478664 |doi=10.1007/s10746-011-9179-8 |s2cid=53580412 }}</ref>
Supporters, such as ], co-author of ], have held more positive views of Rushton's methodologies:
<blockquote>''Rushton is a serious scholar who has assembled serious data. Consider just one example: brain size. The empirical reality, verified by numerous modern studies, including several based on magnetic resonance imaging, is that a significant and substantial relationship does exist between brain size and measured intelligence after body size is taken into account and that the races do have different distributions of brain size.''{{fact}}</blockquote>


Biologist ] argued in 1990 that Rushton "selectively cites and misrepresents his sources to support his conclusions. Far from being an 'honest attempt' to follow the Truth wherever it leads, Rushton seems to be putting a ring through Truth's nose and leading it toward his own barn...He has used, abused, distorted, and in some cases virtually falsified his sources."<ref>{{Cite web |url=https://www.the-scientist.com/?articles.view/articleNo/11124/title/Genetic-Indexing-Of-Race-Groups-Is-Irresponsible-And-Unscientific/ |title=Genetic Indexing Of Race Groups Is Irresponsible And Unscientific |last=Allen |first=Garland E. |date=1990-05-14 |website=] |access-date=2018-04-17}}</ref>
====Penis size claims====
Rushton has claimed that the evolution of intelligence is inversely related to the evolution of penis size, representing a genetic trade-off saying "it's more brain or more penis. You can't have everything." Rushton has not provided any direct evidence to support this assertion, instead relies on examples of evolutionary trade-offs between brain size and reproductive frequency that permeates the r-K evolutionary scale. No study has ever shown a correlation between reproductive frequency and penis size.


According to Charles Lane, in 1988, Rushton conducted a survey at the Eaton Centre mall in ], where he paid 50 whites, 50 blacks, and 50 Asians to answer questions about their sexual habits. Because he did not clear his survey and proposed to pay for answers with the university committee at UWO, the administration reprimanded Rushton, calling his transgression "a serious breach of scholarly procedure", said University President, George Pederson.<ref name="NYB-3-23-95"/>
Critics question Rushton's data on penis size, particularly one study, conducted in 1898 by an anonymous French Army surgeon who traveled through Africa and recorded the size of African penises, and from a second study comparing the penises of Nigerian medical students to Czech army officers. In this study, it turned out the Nigerians penises were longer, and the Czech's had greater circumference. Critics note that if penis girth is used instead of penis length, the Caucasoid sample averaged larger penises. Rushton counters that variablity among samples and overlapp between groups is to be expected, however when aggregating the world-wide literature as a whole, he finds that Negroid penises are not only longest, but thickest also. Rushton points out that almost any confirmed hypothesis can be discredited if one only looks at subsets of data, and does not believe such an approach is useful for making progress in science. Rushton cites studies World Health Organization studies in the United States showing that 9% of black men have penis circumferences exceeding 150 mm, while only 5% of White men do. (See ] for more information regarding Rushton's "aggregation" methodology)


A 1993 study reanalyzed data from a study Rushton had published on the relationship between race and crime and found no strong relationship between the two.<ref>{{cite journal|last=Cernovsky|first=Zach|author-link=Zack Cernovsky|title=Re-Analyses of J.P.

====Is race a valid concept?====
Defenders of Rushton, such as ] believe in the biology of race despite the genetic research which has found greater differences within "races" than between "races". Jensen claimed such conclusions mistaken saying:


In 1995, two researchers published a review and ] concluding that racial differences in behavior were accounted for entirely by environmental factors, which contradicts Rushton's evolutionary theory for the origin of such differences.<ref>{{Cite journal |last1=Gorey |first1=Kevin M. |last2=Cryns |first2=Arthur G. |title=Lack of racial differences in behavior: A quantitative replication of Rushton's (1988) review and an independent meta-analysis |journal=Personality and Individual Differences |volume=19 |issue=3 |pages=345–353 |doi=10.1016/0191-8869(95)00050-g |year=1995|url=https://scholar.uwindsor.ca/socialworkpub/14 }}</ref>
<blockquote>''This is true, however, only if one is comparing the range of individual differences on a given characteristic (or on a number of characteristics) within each population with the range of the differences that exist between the means of each of the separate populations on the given characteristic. In fact, if the differences between the means of the various populations were not larger than the mean difference between individuals within each population, it would be impossible to distinguish different populations statistically.''<ref> from Neoeugenics</ref></blockquote>


] activist ] criticized Rushton's application of ''r''/''K'' selection theory to crime rates and IQ, charging that Rushton ignored things such as systematic/institutional discrimination, racial profiling, economic disparities and unequal access to judicial defense in his attempt to apply ''r''/''K'' Theory and IQ theories to explain racial disparities in American crime rates. He also criticized Rushton and others like him of ignoring things like ] rates, {{blockquote|Corporate criminals, after all, are usually highly educated, and probably would score highly on just about any standardized test you chose to give them.

Despite their claims, mathematically it is possible to distinguish arbitrary groups which have minor differences between means, but more differences within those groups (see ]). For example, blue and green bags of coins may differ as groups, by 2 cents, but within groups larger amounts:


The ] ] criticized Rushton in his 1996 review of the book, ''Race, Evolution, and Behavior'' (1996):

"Racism," then, is the use of racialist assumptions to promote social or political ends, a course that Todorov regards as leading to "particularly catastrophic results."

Cavalli-Sforza’s trees are a bit like the genealogical tree that would show my brother and I as more closely related to each other than to our third cousin: they show that two local populations are more genetically similar than either is to a third population which is farther away.

:''Cavalli-Sforza et al. transformed the distance matrix to a correlation matrix consisting of 861 correlation coefficients among the forty-two populations, so they could apply principal components (PC) analysis on their genetic data...PC analysis is a wholly objective mathematical procedure. It requires no decisions or judgments on anyone's part and yields identical results for everyone who does the calculations correctly...The important point is that if various populations were fairly homogenous in genetic composition, differing no more genetically than could be attributable only to random variation, a PC analysis would not be able to cluster the populations into a number of groups according to their genetic propinquity. In fact, a PC analysis shows that most of the forty-two populations fall very distinctly into the quadrents formed by using the first and second principal component as axes...They form quite widely seperated clusters of the various populations that resemble the "classic" major racial groups-Caucasoids in the upper right, Negroids in the lower right, North East Asians in the upper left, and South East Asians (including South Chinese) and Pacific Islanders in the lower left...I have tried other objective methods of clustering on the same data (varimax rotation of the principal components, common factor analysis, and hierarchical cluster analysis). All of these types of analysis yield essentially the same picture and identify the same major racial groupings.''

One will note that at the same time Jensen defends the idea of race, his self-described analysis undercuts the 3-"race" hierarchy Rushton supports, and instead notes a 4-"race" distribution.

====Native American exception====
Rushton's hypothesis has difficulty explaining why ], who are arguably Mongoloids and emigrated from the northernmost parts of Asia, do not currently have high scores on IQ tests or low crime rates, though their large crania are consistent with Rushton's model.{{fact}} Defenders of Rushton claim that genetic evidence suggests that Native Americans are an archaic form of Mongoloid{{fact}}, and are thus according to Rushton's model, may not be quite as advanced as the rest of the Mongoloid race. Rushton (1995) also argues that lower scores of Native Americans can be attributed to the evolutionary relaxation of cognitive demands due to the more temperate environment and comparative ease with which North American fauna could be hunted. Skeptics of this defense note it can be argued that life along the fertile river plains in China was not particularly harsh, and it is also questionable that conditions in deserts are no less harsh but people living there do not currently score high on IQ tests.

====The Flynn effect====
The most devastating challenge to Rushton's worldwide data on IQ scores concerns the ] and the now well documented fact that industrialization and urbanization causes the average IQ of entire countries to rise by massive amounts. In the Rising Curve, James Flynn argues that whites born in the 19th century were scoring lower not only than contemporary African Americans but obtaining scores perhaps even lower than some contemporary black populations in the third world. This directly contradicts Rushton's claim that Negroids are lower on the IQ scale than Caucasoids.

Rushton has responded to the Flynn Effect by simply claiming that the low IQ's of pre-WWII whites have little to do with general intelligence (]), while the low IQ's obtained by contemporary blacks (even in the third world) are somehow valid reflections of cognitive functioning. Skeptics find that defense particularly weak, finding no reason to believe that a set of results that contradicts his hypothesis should be dismissed arbitrarily.

Defending his position, Rushton wrote:

<blockquote>''principal components analysis shows that whereas the IQ gains over time on the WISC-R and the WISC-III do cluster, suggesting they are a reliable phenomenon, they are independent of the cluster of Black-White differences, inbreeding depression scores, and g factor loadings''</blockquote>

Skeptics find that defense particularly weak, finding no reason to believe that a set of results that contradicts his hypothesis should be dismissed.

Jensen claims that because the bulk of the data on the Flynn Effect comes from after 1950 it is improper to extrapolate the data much further back in time, ironically undercutting Rushton's "aggregation" methodology while defending Rushton (See ] for more information regarding Rushton's "aggregation" methodology).

Rushton also points to a study by Fick that found that black African children obtained a mean IQ 35 points lower than whites in 1929{{fact}}, which he suggests may imply that the gap between the races has been constant, adjusting in lock-step with each other over the 20th century. Challengers of Rushton's claims find these studies more appropriately explained by environmental and cultural conditions, and use the same large gap between past and present groups of the same "race" as prima facie evidence that environment has a greater effect than any racial genetics.

==Social class hypothesis==
Rushton asserts that the r and K traits he claims differentiate the races, also differentiate the social classes within each race, though to a much lesser extent. The lower class, claims Rushton, tend to display characteristics more associated with an r-strategy (low IQ, short lifespans, large families, high crime rates etc). Rushton further contends that these class based differences help explain the rise and fall of civilizations observed throughout the course of world history. He hypothesizes that the more K selected individuals build the civilization, but once the society becomes wealthy, the more numerous off-spring of the r selected members are given the resources to survive. Then, according to his model, as r selected individuals become more numerous, the society lacks the intellect, industriousness, and social order to maintain itself, and thus collapses. According to Rushton, the collapse of the society creates scarce resources and leads to intense competition which favours the more intelligent K selected members. Finally, he asserts that as the K selected members become more numerous, the society is able to rebuild its civilization and the cycle continues.

===Critiques===
Casual inspection of world history suggests that there are alternative reasons for a civilization to rise or fall such as the external effects of invasion, disease, migration and politics.

Psychologist Zack Cernovsky offers criticism of Rushton's application of r/K dimensions:

<blockquote>''The r/K dimension is derived from an extremely wide range of species. Its dogmatic application to the drastically reduced variance within contemporary Homo sapiens is statistically naive (for more detailed explanations, see Cernovsky, 1992). It is not even necessary to be a competent statistician to avoid similar errors. If Rushton (1988, 1990a) could heed Jerison's (1973) warning that racial differences in brain size are at most minor and "probably of no significance for intellectual differences," he would not attempt to extend Jerison' s findings across species to subgroups within modern mankind. Instead, Rushton (1991) misleadingly refers to Jerison in a manner that implies an expert support from this famous comparative neuropsychologist, without mentioning their disagreement on the most central issue.''<ref> Vol. 25, Journal of Black Studies, 07-01-1995, pp 672.</ref></blockquote>

=Controversy and criticism=
Popular science commentator ] protested the theory and spoke out against Rushton in a live televised debate at the ]. "There will always be Rushtons in science," Suzuki thundered "and we must always be prepared to root them out!". Rushton is accused by critics of advocating a new ] movement <ref></ref>, and is openly praised by proponents of eugenics.<ref>http://www.eugenics.net/ Website including prominent reference to Rushton's works</ref>

Rushton has been considered by many scholars to be more of a self-promoter than serious scientist. After mass mailing a booklet to psychology, sociology and anthropology professors across North America based on his racial papers, Hermann Helmuth, a professor of anthropology at Trent University, said, "It is in a way personal and political propaganda. There is no basis to his scientific research."<ref> Psych prof accused of racism</ref>

Since 2002, Rushton has been the president of the controversial ], which aims "to advance the scientific study of heredity and human differences." Rushton's work has received grants from the fund totalling over $1 million USD since 1981.

Rushton's sources, such as semi-pornographic books and the ] magazine, have been dismissed by other researchers, or have been criticized as extremely biased and inadequate reviews of the literature, or simply false . There have also been many other criticisms of the theory . Actual recent data show that blacks are not more psychopathic , nor do they differ from whites when testing for the ] , differences in sex hormones between whites and East Asians are best explained by environmental differences , and the fundamental prediction of the theory that blacks have a higher frequency of twins is disputed by some sources . However, the rate of twin births in the US has doubled since 1971, the time of the study Rushton cited, due to older mothers (for which twin births are naturally more common) and fertility treatments, both demographic characteristics that are more common among Whites.

==Professional opinions==
Some scientists have come to Rushton's defense, including ] biologist ] who is one of the two cofounders of r/K theory said:

<blockquote>''I think Phil is an honest and capable researcher ... The basic reasoning by Rushton is solid evolutionary reasoning; that is it's logically sound. If he had seen some apparent geographic variation for a non-human species-a species of sparrow or sparrow hawk, for example-no one would have batted an eye.''{{fact}}</blockquote>

Psychologist David P. Barash wrote in a scholarly review:

<blockquote>''I don't know which is worse, Rushton's scientific failings or his blatant racism. At least Rushton has a theory, namely, r- and K-selection. In brief, he argues that `Negroids' are relatively r-selected, `Mongoloids' K-selected, and `Caucasoids' in between. All racial distinctions are then seen to derive from this grand pattern, from differences in genital anatomy, to reproductive regimes, to IQ, etc. He even points to the higher frequency of low birth weight babies among black Americans, data that are undeniably consistent with an r-selection regime, but which might also be attributed to poor nutrition and insufficient prenatal care, and which, not coincidentally, have other implications for behaviour, IQ not the least. I suspect that r- and K-selection does in fact have some relevance to variations in human behaviour, notably the so-called demographic transition, whereby economic development characteristically leads to reduced family size, and, moreover, a greater reliance on a variety of `K-type' traits. But this is a pan-human phenomenon, a flexible, adaptive response to changed environmental conditions of lowered mortality and greater pay-off attendant upon concentrating parental investment in a smaller number of offspring Rushton wields r- and K-selection as a Procrustean bed, doing what he can to make the available data fit"''{{fact}}</blockquote>

Barash ends his lengthy review with the sentence: "Bad science and virulent racial prejudice drip like pus from nearly every page of this despicable book".

Psychologist and ] scholar ] had a more favorable opinion:

<blockquote>''This brilliant book is the most impressive theory-based study...of the psychological and behavioral differences between the major racial groups that I have encountered in the world literature on this subject.''{{fact}}</blockquote>

] of the ] adds:

<blockquote>''Professor Rushton is widely known and respected for the unusual combination of rigour and originality in his work....Few concerned with understanding the problems associated with race can afford to disregard this storehouse of well-integrated information which gives rise to a remarkable synthesis.''{{fact}}</blockquote>

Psychologist and associate editor of the journal "Mankind Quarterly" ] wrote:

<blockquote>''Should, if there is any justice, receive a Nobel Prize.''{{fact}}</blockquote>

Dr. Barry Mehler wrote critically of Rushton's misrepresentation of research he cites:

<blockquote>''"Rushton's theories are a bizarre mélange of nineteenth century anthro-pometrism and twentieth century eugenics. Although there is no evidence showing different cranial sizes between races, Rushton has cited the genetic distance studies of Allen Wilson of the University of California to claim that Africans have smaller brains and are more primitive than whites and orientals, who evolved to cope with the more demanding northern climes. Wilson commented: 'He is misrepresenting our findings'. These 'show that Asians are as closely related to modern Africans as Europeans are'. When asked if he was aware of any anthropological evidence at all that might support Rushton's claim, he replied, 'I'm not aware of any such evidence. The claim shocks and dismays me'.''<ref> by Dr. Barry Mehler</ref></blockquote>

Dr. Mark Feldman, Stanford University Population Biologist and recognized authority on r/K selection theory, claims that r/K is "absolutely inapplicable" to differences between humans. Feldman concluded that Rushton's work "doesn't really classify as science ... it has no content, it is laughable".<ref>CBC Radio, 18 February 1989</ref>

] scholar Christopher Brand said:

<blockquote>''The media and even the scientists themselves can hedge and fudge all they like, but their favorite "post-modern" pretense that there is no such thing as race is looking sillier all the time.''{{fact}}</blockquote>

==Brain size gene==
Over a decade and a half since the media firestorm over Rushton's views first erupted,
University of Chicago geneticists published data in the journal Science that links
two sets of genetic variations (alleles) to brain size, race, and spurts in human
evolution. These genetic variations were relatively common in Europe and Asia, but significantly less frequent in sub-Saharan Africa. These genetic variations were also only a small subset of all variations which affect brain size, and the researchers have specifically cautioned against asserting functional race-based differences based on their findings.

Earlier, these researchers showed these genetic variations to be much more frequent in humans than in other mammals, though the chimpanzees, who are closest to humans in DNA, showed levels that suggest significant evolution in the direction of humans. This work has been carried out under the direction of a Dr. Bruce Lahn whose
team had studied the prevalence of variants of two genes that are disabled or damaged
in human cases of severe microcephaly, in which the brain develops to only 30 percent its normal size. The fact that they are damaged in microcephalics is thought to indicate that they are necessary for normal brain growth.

Dr. Lahn's team examined the DNA of 1,184 people around the
world-excluding racially mixed areas like North America, Russia and Australia.
They estimated that one undamaged variation, microcephalin haplogroup D (sometimes called variation one, or V1) first appeared around 40,000 BC
and has since spread to some 70 percent of humans. It is more common in Europe,
Asia, South America and Latin America than in sub-Saharan Africa. At three
percent, it is especially rare in Congo pygmies, who are at the bottom of black Africa's socio-economic ladder and along with Khoisans, split off the black family tree much earlier than other black groups.{{fact}}

Dr. Lahn and colleagues noted that the arrival of V1 coincided roughly with the
first signs of human habitation and agriculture; V2 appeared about the time of
the first cities and the development of written language.

Ultimately, very little is known about the actual impact of these variants - the researchers caution that they may not have anything to do with cognition or intelligence at all.<ref> "Lahn’s analysis of genes indicates human brain continues to evolve."</ref>

This research is seen by some as directly contradicting Rushton's proposed "evolution" of the races, demonstrating biogeographic evolution occuring as recently as 500 years ago, rather than 200,000, 110,000 or 41,000 years ago.

A team at the University of California, Los Angeles, recently tested whether the gene variants studied by Lahn actually affect brain size. They studied DNA from 120 people whose brain volumes they had already measured using magnetic-resonance imaging. They didn't find any difference. Roger P. Woods, a UCLA brain-mapping expert stated, "It certainly makes you want to look at other explanations".

John Philippe Rushton (December 3, 1943 – October 2, 2012) was a Canadian psychologist and author. He taught at the University of Western Ontario until the early 1990s, and became known to the general public during the 1980s and 1990s for research on race and intelligence, race and crime, and other purported racial correlations.

Rushton's work has been heavily criticized by the scientific community for the questionable quality of its research, with many academics arguing that it was conducted under a racist agenda. From 2002 until his death, he served as the head of the Pioneer Fund, an organization founded in 1937 to promote eugenics, which has been described as racist and white supremacist in nature, and as a hate group by the Southern Poverty Law Center. He also published articles in and spoke at conferences organized by the white supremacist magazine American Renaissance.

Rushton was a Fellow of the Canadian Psychological Association and a onetime Fellow of the John Simon Guggenheim Memorial Foundation. In 2020, the Department of Psychology of the University of Western Ontario released a statement stating that "much of research was racist", was "deeply flawed from a scientific standpoint", and "Rushton's legacy shows that the impact of flawed science lingers on, even after qualified scholars have condemned its scientific integrity." As of 2021, Rushton has had six research publications retracted for being scientifically flawed, unethical, and not replicable, and for advancing a racist agenda despite contradictory evidence.

Early life and education

Rushton was born in Bournemouth, England. During his childhood, he emigrated with his family to South Africa, where he lived from age four to eight (1948–1952). His father was a building contractor and his mother came from France. The family moved to Canada, where Rushton spent most of his teen years. He returned to England for university, receiving a B.Sc. in psychology from Birkbeck College at the University of London in 1970, and, in 1973, his Ph.D. in social psychology from the London School of Economics for work on altruism in children. He continued his work at the University of Oxford until 1974.

Later life and career

Rushton taught at York University in Canada from 1974 to 1976 and the University of Toronto until 1977. He moved to the University of Western Ontario and was made full professor (with tenure) in 1985. He received a D.Sc. from the University of London in 1992. His controversial research has sparked political debates, and Ontario Premier David Peterson called Rushton a racist. In 2005, The Ottawa Citizen described Rushton as the most famous university professor in Canada.

He published more than 250 articles and six books, including two on altruism, and one on scientific excellence, and co-authored an introductory psychology textbook. He was a signatory of the opinion piece "Mainstream Science on Intelligence."

Rushton died of cancer on October 2, 2012, at the age of 68.

Work and opinions

Genetic similarity theory

Early in his career, Rushton did research on altruism. He theorized a heritable component in altruism and developed Genetic Similarity Theory, which is an extension of W.D. Hamilton's theory of kin selection. It holds that individuals tend to be more altruistic to individuals who are genetically similar to themselves even if they are not kin, and less altruistic, and sometimes outwardly hostile, to individuals who are less genetically similar. Rushton describes "ethnic conflict and rivalry" as "one of the great themes of historical and contemporary society", and suggests that this may have its roots in the evolutionary impact on individuals from groups "giving preferential treatment to genetically similar others". According to Rushton: "the makeup of a gene pool causally affects the probability of any particular ideology being adopted".

Articles in a 1989 issue of Behavioral and Brain Sciences criticized the theory. Judith Anderson said his work was based on statistically flawed evidence, John Archer and others said that Rushton failed to understand and misapplied the theory of kin selection, Judith Economos said that Rushton's analysis was speculative, that he failed to define the concept of altruistic behavior in a way that it can become manifest, and that he failed to show any plausible mechanism by which members of a species can detect the "altruism gene" in other members of the species. Steven Gangestad criticized Rushton's theory for not being compelling in terms of its attractiveness as an explanatory model. C.R. Hallpike said Rushton's theory failed to take into account that many other traits, ranging from age, sex, social and political group membership, are observably more important in predicting altruistic behavior between non-kin than genetic similarity. John Hartung criticized Rushton for failing to conduct an adequate control group study and for ignoring contradictory evidence.

Littlefield and Rushton (1984) examined degree of bereavement among parents after the death of a child. They found that children perceived as more physically similar to their parents were grieved for more intensely than less similar children. Russell, Wells, and Rushton (1985) reanalyzed several previous studies on similarities between spouses and concluded there is higher similarity on the more heritable characteristics. In 1988 Rushton examined blood group genes and found that sexually interacting couples had more similar blood group genes than randomly paired individuals.

Race and intelligence

Rushton spent much of his career arguing that average IQ differences between racial groups are due to genetic causes, a view that was controversial at the time and is now broadly rejected by the scientific consensus. His research areas included studying brain size and the effects of racial admixture.

In a 2020 statement, his former department at the University of Western Ontario stated: "Rushton's works linking race and intelligence are based on an incorrect assumption that fuels systemic racism, the notion that racialized groups are concordant with patterns of human ancestry and genetic population structure." Furthermore, they stated that Rushton's work on the topic is "characterized by a complete misunderstanding of population genetic measures, including fundamental misconceptions about the nature of heritability."

Application of r/K selection theory to race

Main article: Differential K theory

Rushton's book Race, Evolution, and Behavior (1995) attempted to use r/K selection theory to explain what he described as an evolutionary scale of characteristics indicative of nurturing behavior in which East Asian people consistently averaged high, black people low, and white people in the middle. He first published this theory in 1984. Rushton argued that East Asians and their descendants average a larger brain size, greater intelligence, more sexual restraint, slower rates of maturation, and greater law abidingness and social organization than do Europeans and their descendants, whom he argued average higher scores on these measures than Africans and their descendants. He hypothesized that r/K selection theory explains these differences.

Rushton's application of r/K selection theory to explain differences among racial groups has been widely criticized. Differential K theory in particular was described in a 2020 statement by Rushton's former department at Western Ontario University as "thoroughly debunked."

One of his many critics is the evolutionary biologist Joseph L. Graves, who has done extensive testing of the r/K selection theory with species of Drosophila flies. Graves argues that not only is r/K selection theory considered to be virtually useless when applied to human life history evolution, but Rushton does not apply the theory correctly, and displays a lack of understanding of evolutionary theory in general. Graves also says that Rushton misrepresented the sources for the biological data he gathered in support of his hypothesis, and that much of his social science data was collected by dubious means. Other scholars have argued against Rushton's hypothesis on the basis that the concept of race is not supported by genetic evidence about the diversity of human populations, and that his research was based on folk taxonomies.

Later studies by Rushton and other researchers have argued that there is empirical support for the theory, though these studies too have been criticized.

Psychologist David P. Barash observed that r- and K-selection may have some validity when considering the so-called demographic transition, whereby economic development characteristically leads to reduced family size and other K traits. "But this is a pan-human phenomenon, a flexible, adaptive response to changed environmental conditions ... Rushton wields r- and K-selection as a Procrustean bed, doing what he can to make the available data fit ... Bad science and virulent racial prejudice drip like pus from nearly every page of this despicable book."

Dimensional structure of personality

Beginning in 2008, Rushton researched the structure of personality. Over about a dozen papers, he argued that variation in personality can be explained by variation in a single underlying "general factor," similar to the g factor of psychometrics.

Opinions

In 2009 Rushton spoke at the Preserving Western Civilization conference in Baltimore. It was organized by Michael H. Hart for the stated purpose of "addressing the need" to defend "America's Judeo-Christian heritage and European identity" from immigrants, Muslims, and African Americans. The Anti-Defamation League described the conference attendees as "racist academics, conservative pundits and anti-immigrant activists".

Reception

Press coverage

Rushton prompted controversy for years, attracting coverage from the press as well as comments and criticism by scientists of his books and journal articles.

First-year psychology students who took Rushton's classes said that he had conducted a survey of students' sexual habits in 1988, asking "such questions as how large their penises are, how many sex partners they have had, and how far they can ejaculate". First-year psychology students at the University of Western Ontario are required "to participate in approved surveys as a condition of their studies. If they choose not to, they must write one research paper. Also, many students feel subtle pressure to participate in order not to offend professors who may later be grading their work. However, if a study is not approved, these requirements do not apply at all." For his failing to tell students they had the option not to participate in his studies without incurring additional work, the university barred Rushton for two years from using students as research subjects. He had tenure at UWO.

In a 2005 Ottawa Citizen article, Rushton stated that the public perceives disproportionately negative effects caused by black residents "in every bloody city in Canada where you have black people." In the same article, Rushton suggested that equalizing outcomes across groups was "impossible". The Southern Poverty Law Center called the piece "yet another attack" by Rushton, and it criticized those who published his work and that of other "race scientists".

Academic opinion

Favorable

In a 1991 work, the Harvard biologist E. O. Wilson (one of the two co-founders of the r/K selection theory which Rushton uses) was quoted as having said about him:

I think Phil is an honest and capable researcher. The basic reasoning by Rushton is solid evolutionary reasoning; that is, it is logically sound. If he had seen some apparent geographic variation for a non-human species – a species of sparrow or sparrow hawk, for example – no one would have batted an eye.  ... hen it comes to racial differences, especially in the inflamed situation in this country, special safeguards and conventions need to be developed.

Three years after the publication of Wilson's 1975 book Sociobiology: The New Synthesis, Rushton had already begun a long correspondence with Wilson. The letters became particularly extensive between 1987 and 1995 (Wilson's letters have now been archived by the Library of Congress). After Wilson's death at the end of 2021, historians of science Mark Borrello and David Sepkoski have reassessed how Wilson's thinking on issues of race and evolution was influenced by Rushton.

In a 1995 review of Rushton's Race, Evolution, and Behavior, anthropologist and population geneticist Henry Harpending expressed doubt as to whether all of Rushton's data fit the r/K model he proposed, but nonetheless praised the book for its proposing of a theoretical model that makes testable predictions about differences between human groups. He concludes that "Perhaps there will ultimately be some serious contribution from the traditional smoke-and-mirrors social science treatment of IQ, but for now Rushton's framework is essentially the only game in town." In their 2009 book The 10,000 Year Explosion, Harpending and Gregory Cochran later described Rushton as one of the researchers to whom they are indebted.

The psychologists Arthur Jensen, Hans Eysenck, Richard Lynn, Linda Gottfredson and Thomas Bouchard had a high opinion of Rushton's Race, Evolution and Behavior, describing Rushton's work as rigorous and impressive. However, many of these researchers are themselves controversial and they all received money from the Pioneer Fund, which had funded much of Rushton's work when these reviews were written.

Some criminologists who study the relationship between race and crime regard Rushton's r/K theory as one of several possible explanations for racial disparities in crime rates. Others, such as the criminologist Shaun L. Gabbidon, think that Rushton has developed one of the more controversial biosocial theories related to race and crime; he says that it has been criticized for failing to explain all of the data and for its potential to support racist ideologies. The criminologist Anthony Walsh has defended Rushton, claiming that none of Rushton's critics has supplied data indicating anything other than the racial gradient he identifies, and that it is unscientific to dismiss Rushton's ideas on the basis of their political implications.

Unfavorable

On 22 June 2020, the Department of Psychology at the University of Western Ontario issued a statement regarding their former faculty member, which read in part:

Despite its deeply flawed assumptions and methodologies, Rushton's work and other so-called "race science" (currently under the pseudonym of "race realism") continues to be misused by white supremacists and promoted by eugenic organizations. Thus, Rushton's legacy shows that the impact of flawed science lingers on, even after qualified scholars have condemned its scientific integrity. Academic freedom and freedom of expression are critical to free scientific inquiry. However, the notion of academic freedom is disrespected and abused when it is used to promote the dissemination of racist and discriminatory concepts. Scientists have an obligation to society to speak loudly and actively in opposition of such abuse.

Also in 2020, Andrew Winston summarized Rushton's scholarly reception as follows: "Rushton's work was heavily criticized by psychologists, evolutionary biologists, anthropologists, and geneticists for severe scientific inadequacies, fundamental errors, inappropriate conceptualization of race, inappropriate statistical comparisons, misuse of sources, and serious logical errors and flaws."

In 1989, geneticist and media personality David Suzuki criticized Rushton's racial theories in a live televised debate at the University of Western Ontario. He said: "There will always be Rushtons in science, and we must always be prepared to root them out". At the same occasion, Rushton rejected believing in racial superiority, saying "we've got to realize that each of these populations is perfectly, beautifully adapted to their own ancestral environments".

Also in 1989, Michael Lynn published a paper in the Journal of Research in Personality criticizing a study by Rushton & Bogaert that had been published in the same journal two years earlier. Lynn cited four reasons he considered Rushton & Bogaert's study to be flawed:

First, they did not explain why natural selection would have favored different reproductive strategies for different races. Second, their data on race differences are of questionable validity because their literature review was selective and their original analyses were based on self-reports. Third, they provided no evidence that these race differences had significant effects on reproduction or that sexual restraint is a K characteristic. Finally, they did not adequately rule out environmental explanations for their data.

Marvin Zuckerman, psychology professor of the University of Delaware, criticized Rushton's research on methodological grounds, observing that more variation exists in personality traits within racial groups than between them and arguing that Rushton selectively cited data from the Eysenck Personality Questionnaire.

Critical psychologist Thomas Teo argued that Rushton's "substantial success and influence in the discipline" and use of "accepted usage of empirical mainstream methods" pointed to broader problems in academic psychology.

Biologist Garland E. Allen argued in 1990 that Rushton "selectively cites and misrepresents his sources to support his conclusions. Far from being an 'honest attempt' to follow the Truth wherever it leads, Rushton seems to be putting a ring through Truth's nose and leading it toward his own barn...He has used, abused, distorted, and in some cases virtually falsified his sources."

According to Charles Lane, in 1988, Rushton conducted a survey at the Eaton Centre mall in Toronto, where he paid 50 whites, 50 blacks, and 50 Asians to answer questions about their sexual habits. Because he did not clear his survey and proposed to pay for answers with the university committee at UWO, the administration reprimanded Rushton, calling his transgression "a serious breach of scholarly procedure", said University President, George Pederson.

A 1993 study reanalyzed data from a study Rushton had published on the relationship between race and crime and found no strong relationship between the two.

Rushton's work was criticized in the scholarly literature; he generally responded, sometimes in the same journal. In 1995, in the Journal of Black Studies, Zack Cernovsky wrote: "some of Rushton's references to scientific literature with respects to racial differences in sexual characteristics turned out to be references to a nonscientific semi-pornographic book and to an article by Philip Nobile in the Penthouse magazine's Forum."

In 1995, two researchers published a review and meta-analysis concluding that racial differences in behavior were accounted for entirely by environmental factors, which contradicts Rushton's evolutionary theory for the origin of such differences.

Anti-racism activist Tim Wise criticized Rushton's application of r/K selection theory to crime rates and IQ, charging that Rushton ignored things such as systematic/institutional discrimination, racial profiling, economic disparities and unequal access to judicial defense in his attempt to apply r/K Theory and IQ theories to explain racial disparities in American crime rates. He also criticized Rushton and others like him of ignoring things like white-collar crime rates,

Corporate criminals, after all, are usually highly educated, and probably would score highly on just about any standardized test you chose to give them. And what of it? Virtually all the stock manipulators, unethical derivatives traders and shady money managers on Wall Street, whose actions have brought the economy to its knees of late — and who it might be worth noting are pretty much all white men — would likely do well on the Stanford-Binet or Wonderlich Industrial Aptitude Test. They probably were above-average students. But what are we to make of these facts? Clearly they say little about the value of such persons to the nation or the world. The Unabomber was a certified genius and Ted Bundy was of well-above-average intelligence... But I'm having a hard time discerning what we should conclude about these truths, in terms of how much emphasis we place on intelligence, as opposed to other human traits.

The biological anthropologist C. Loring Brace criticized Rushton in his 1996 review of the book, Race, Evolution, and Behavior (1996):

Virtually every kind of anthropologist may be put in the position of being asked to comment on what is contained in this book, so, whatever our individual specialty, we should all be prepared to discuss what it represents. Race, Evolution, and Behavior is an amalgamation of bad biology and inexcusable anthropology. It is not science but advocacy, and advocacy for the promotion of "racialism." Tzvetan Todorov explains "racialism," in contrast to "racism," as belief in the existence of typological essences called "races" whose characteristics can be rated in hierarchical fashion (On Human Diversity: Nationalism, Racism, and Exoticism in French Thought, Cambridge, MA: Harvard University Press, 1993, p. 31). "Racism," then, is the use of racialist assumptions to promote social or political ends, a course that Todorov regards as leading to "particularly catastrophic results." Perpetuating catastrophe is not the stated aim of Rushton's book, but current promoters of racist agendas will almost certainly regard it as a welcome weapon to apply for their noxious purposes.

Robert Sussman, an evolutionary anthropologist and the editor-in-chief of American Anthropologist, explained why the journal did not accept ads for Rushton's 1998 book:

This is an insidious attempt to legitimize Rushton's racist propaganda and is tantamount to publishing ads for white supremacy and the neo-Nazi party. If you have any question about the validity of the "science" of Rushton's trash you should read any one of his articles and the many rebuttals by ashamed scientists.

In 2000, after Rushton mailed a booklet on his work to psychology, sociology, and anthropology professors across North America, Hermann Helmuth, a professor of anthropology at Trent University, said: "It is in a way personal and political propaganda. There is no basis to his scientific research." Rushton responded, "It's not racist; it's a matter of science and recognizing variation in all groups of people."

From 2002, Rushton was the president of the Pioneer Fund. Tax records show that in 2002 his Charles Darwin Research Institute was awarded $473,835, or 73% of the fund's total grants that year. The Southern Poverty Law Center, an American civil rights organization, characterizes the Pioneer Fund as a hate group. Rushton had spoken on eugenics several times at conferences of the American Renaissance magazine, a monthly white supremacist magazine, in which he had also published a number of general articles.

Rushton published articles on the website VDARE, which advocates for reduced immigration into the United States. Stefan Kühl wrote in his book, The Nazi Connection: Eugenics, American Racism, and German National Socialism (2002), that Rushton was part of the revival in the 1980s of public interest in scientific racism.

William H. Tucker, a professor of psychology and expert on the history of scientific racism, observed in 2002:

Rushton has not only contributed to American Renaissance publications and graced their conferences with his presence but also offered praise and support for the "scholarly" work on racial differences of Henry Garrett, who spent the last two decades of his life opposing the extension of the Constitution to blacks on the basis that the "normal" black resembled a European after frontal lobotomy. Informed of Garrett's assertion that blacks were not entitled to equality because their "ancestors were ... savages in an African jungle," Rushton dismissed the observation as quoted "selectively from Garrett's writing", finding nothing opprobrious in such sentiments because the leader of the scientific opposition to civil rights had made other statements about black inferiority that were, according to Rushton, "quite objective in tone and backed by standard social science evidence." Quite apart from the questionable logic in defending a blatant call to deprive citizens of their rights by citing Garrett's less offensive writing—as if it were evidence of Ted Bundy's innocence that there were some women he had met and not killed—there was no sense on Rushton's part that all of Garrett's assertions, whether or not "objective," were utterly irrelevant to constitutional guarantees, which are not predicated on scientific demonstrations of intellectual equality.

A 2003 study in Evolution and Human Behavior found no evidence to support Rushton's hypothesized relationship between race and behavior.

In 2005, Lisa Suzuki and Joshua Aronson of New York University wrote an article for Psychology, Public Policy, and Law noting that Rushton ignored evidence that failed to support his position that IQ test score gaps represent a genetic racial hierarchy. He did not change his position on this matter for 30 years. Rushton replied in the same issue of the journal.

In a paper for the International Journal of Selection and Assessment in 2006, Steven Cronshaw and colleagues wrote that psychologists need to critically examine the science used by Rushton in his "race-realist" research. Their re-analysis of the validity criteria for test bias, using data reported in the Rushton et al. paper, led them to conclude that the testing methods were biased against Black Africans. They disagree with other aspects of Rushton's methodology, such as his use of non-equivalent groups in test samples. Rushton responded in the next issue of the journal. He said why he believed his results were valid, and why he thought the criticisms incorrect.

Scott McGreal (2012) in Psychology Today criticized the science of Rushton's "Race Differences in Sexual Behavior: Testing an Evolutionary Hypothesis". He cited Weizmann, Wiener, Wiesenthal, & Ziegle, which argued that Rushton's theory relied on flawed science. McGreal faulted Rushton and his use of Nobile's penis size study.

On 17 June 2020, academic publisher Elsevier announced it was retracting an article that Rushton and Donald Templer had published in 2012 in the Elsevier journal Personality and Individual Differences. The article falsely claimed that there was scientific evidence that skin color was related to aggression and sexuality in humans.

On 24 December 2020, the academic journal Psychological Reports retracted two Rushton articles about intelligence and race. Review of the articles, which were originally published in the 1990s, "found that the research was unethical, scientifically flawed, and based on racist ideas and agenda". On 23 August 2021, it retracted three more.
