He was in favour of
homosexual law reform in New Zealand and in 1985 listed his name openly in support. While teaching at Otago in the 1990s, Flynn became a founding member of the
NewLabour and
Alliance political parties. He stood unsuccessfully as an Alliance candidate for the
New Zealand House of Representatives in general elections in the electorate in , , and elections. In 2008 he acted as the Alliance spokesperson for finance and taxation. In 1996, Flynn stepped down as head of the University of Otago's politics department and in 1997, he became
Emeritus Professor in the Politics and Psychology departments. In 1999, Flynn had surgery for intestinal cancer, which remained in remission for twenty years. A 1999 article published in
American Psychologist summarised much of his research up to that point. On the alleged genetic inferiority of Blacks on IQ tests, he lays out the argument and evidence for such a belief and then contests each point. He interprets the direct evidence—when Blacks are raised in settings that are less disadvantageous—as suggesting that environmental factors explain average group differences. And yet, he argues that the environmental explanation gained force after the discovery that IQ scores were rising over time. Inter-generational IQ differences among Whites and across nations were larger than the Black-White IQ Gap and could not be accounted for by genetic factors, which, if anything, should have reduced IQ, according to scholars he references. In that and in later works, he posited that the Black-White IQ score gap can be largely explained by environmental factors if "the average environment for Blacks in 1995 matches the quality of the average environment for Whites in 1945." In 2000, Flynn published what he considered his most important book,
How to Defend Humane Ideals, which he dedicated to his wife and which was a "recalibration" of the "modern
Aristotelianism" of his earlier 1973 work,
Humanism and Ideology. In 2006, with
Brookings Institution economist
William T. Dickens, Flynn published "Black Americans reduce the racial IQ gap: evidence from standardization samples", which suggested that the difference in IQ scores between blacks and whites narrowed by four to seven points between 1972 and 2002, a conclusion contested by Jensen and controversial
University of Western Ontario psychologist
J. Philippe Rushton. Flynn's 2007 book,
What is Intelligence? Beyond the Flynn Effect, was dedicated to Jensen and revisited and expanded upon his earlier work from the 1980s. During 2007, new research from the
2006 New Zealand census showed that women without a tertiary (college) education had produced 2.57 babies each, compared to 1.85 babies for those women with a higher education. During July 2007,
The Sunday Star-Times quoted Flynn as saying that New Zealand
risked having a less intelligent population and that a "persistent genetic trend which lowered the genetic quality for brain physiology would have some effect eventually". He referred to hypothetical
eugenicists' suggestions for reversing the trend, including some sort of
oral contraceptive "in the water supply and … an antidote" to conceive. Flynn later articulated his own views on the
Close Up television programme in an interview with
Paul Henry, suggesting that the
Sunday Star-Times had grossly misrepresented his opinions. In the article, Flynn argued that he never intended for his suggestion to be taken seriously, as he only said this to illustrate a particular point. Flynn continued teaching and was a prolific author in his later life, publishing almost a book every year in his last decade on a number of topics. Flynn wrote a variety of books. His research interests included humane ideals and ideological debate, classics of
political philosophy, and race, class and IQ (see
race and intelligence). His books combined political and moral philosophy with
psychology to examine problems such as justifying humane ideals and whether it makes sense to rank
races and
classes by merit. Despite the success of his work on IQ, Flynn considered himself primarily a philosopher who had simply taken a "holiday" in psychology. 2008's
Where have all the liberals gone? Race, class, and ideals in America argued that American liberalism had lost its way in response to alarmism from American conservatism. In 2010, Flynn published
The Torchlight List: Around the World in 200 Books, which analysed world literature and proposed that a person can learn more from reading great works of literature than they can from going to university. Flynn published three books in 2012.
Are We Getting Smarter? Rising IQ in the Twenty-First Century summarised his past IQ work and responded to criticisms, particularly regarding environmental causes for race and gender IQ gaps.
Beyond patriotism: From Truman to Obama (2012) critiqued US foreign policy, and suggested people should put allegiance to the world community above national allegiances. ''Fate & philosophy: A journey through life's great questions'' discussed science, ethics, religion, and free will. In July 2012, several media outlets reported Flynn as saying that women had, for the first time in a century, surpassed men on IQ tests based on a study he conducted in 2010. However, Flynn announced that the media had seriously distorted his results and went beyond his findings, revealing that he had instead discovered that the differences between men and women on one particular test, the
Raven's Progressive Matrices, had become minimal in five modernised nations (whereas before 1982 women had scored significantly lower). Women, he argued, caught up with men in these nations as a result of exposure to modernity by entering the professions and being allowed greater educational access. Therefore, he said, when a total account of the Flynn effect is considered, women's closing the gap had moved them up in IQ slightly faster than men as a result. Flynn had previously documented this same trend among ethnic minorities and other disadvantaged groups. According to Flynn, the sexes are "dead equal on cognitive factors ... in their ability to deal with using logic on the abstract problems of Raven's", but that temperamental differences in the way boys and girls take the tests likely account for the tiny variations in mean scores, rather than any difference in intellectual ability. In the preface, Flynn stated that it was thought too controversial by Emerald under
the United Kingdom's laws about hate speech as the intent is irrelevant if it is thought likely that "racial hatred could be stirred up as a result of the work". He became an Honorary Fellow for life of the
New Zealand Psychological Society and in 1998 received its Special Award. In 2002, he was awarded the university's gold medal for Distinguished Career Research. In 2007, he became a Distinguished Contributor of the
International Society for Intelligence Research. He received an honorary Doctorate of Science from the University of Otago in 2010. He was a
Fellow of the Royal Society of New Zealand and in 2011 received its Aronui Medal, Distinguished Visiting Fellow at the
Hoover Institution, Distinguished Visiting Speaker at
Cornell University, and Distinguished Associate of The Psychometrics Centre at
Cambridge University. Flynn was a member of the editorial board of
Intelligence and on the Honorary International Advisory Editorial Board of the
Mens Sana Monographs. Flynn retired in 2020. His cancer returned, and he underwent liver surgery that May. Flynn's wife described his final year as "difficult". Flynn died of intestinal cancer at Yvette Williams Retirement Village in Dunedin on 11 December 2020, aged 86. == Partial bibliography ==
