Whitney was the author of over 60 papers on the genetics of taste sensitivity in inbred mice. Support for some of this work came from a Claude Pepper Award for Research Excellence from the National Institute on Deafness and Other Communication Disorders and in 1994 he received the Manheimer Lectureship Award from the Monell Chemical Senses Center, which recognizes career achievements of individuals in the chemosensory sciences. He was the president of the Behavior Genetics Association from 1994 to 1995. By 1999, Whitney has shifted from studying mice to researching race and intelligence in humans. As part of this research, Whitney was supported by the Pioneer Fund, which has ties to scientific racism.
Political views
Whitney was a frequent contributor to magazines such as Mankind Quarterly, The g Factor Newsletter and The William McDougall Newsletter. While outgoing president of the Behavior Genetics Association in 1995, some members of this group demanded his resignation after his presidential address suggested the need to investigate the possibility of genetic factors behind the high incidence of black crime in America. Whitney wrote the foreword for , an autobiography by David Duke, a white nationalist politician and former National Director of the Knights of the Ku Klux Klan. In the book, Duke uses scientific racism to push for the re-segregation of schools. Whitney did not specifically endorse Duke's re-segregation plan, but described Duke as "a Moses-like prophet". Whitney compared Duke to Socrates, Galileo, and Newton and said the NAACP and other "front organisations" had been created to further Jewish interests. Whitney said in a 1999 interview that the controversy distracted from what was meant to be a scientific discussion, saying "races are different for many genetic systems that influence everything from behavior and psychology to physiology, medicine and sports Screaming nasty words does not change the reality." Following the publication of the book, faculty and students of FSU condemned Whitney's comments, with some calling for his resignation. The school rejected Whitney's position, but defended his right to teach as a matter of academic freedom. Whitney's views regarding race and intelligence prompted the Florida Senate to pass Resolution 2742 in 1999, "condemning the racism and bigotry espoused by Florida StateUniversity Professor Glayde Whitney." Whitney acknowledged the scientific achievements of Jews, but accused "organized Jewry" of playing a prominent role in suppressing race behavioral genetics in response to racism directed toward them, resulting in a "dishonest and hypocritical version of egalitarianism." Whitney was a member of the Institute for Historical Review, an organization promoting Holocaust denial, making a case that Jews invented the Holocaust creating a "fake" for their own interests.
