I was the external examiner on Dr. Carl’s DPhil from Nuffield, Oxford, so I am familiar with his work. It is a data-intensive investigation of cognitive ability (or intelligence) and its correlates, including ideological views, trust, and self-rated happiness. He wrote a report for the classical liberal Adam Smith Institute on why British academics lean left, and argued that intelligence does not work as explanation. He has published several analyses of the Brexit vote. He follows the scientific literature in recognizing that both “nature” and “nurture” affect the development of cognitive ability. He has not conducted research on race or ethnicity as factors in cognitive ability, but he has written a courageous and thoughtful essay about the ethics of preemptively shutting down such research.
Dr. Carl, then, is a serious and highly accomplished researcher who simply does not conform to leftist ways of interpreting the world and who is not cowed by leftist taboos. As such, he has been singled out as a miscreant. Disgraceful means have been used to take him down. The charges are defamatory.
I read about the rescinding in a May 1 article in Varsity. No less than three times does the article quote Dr. Carl’s former employer saying that he had “collaborated with a number of individuals who were known to hold extremist views,” without naming a single such individual. It notes that Dr. Carl attended a conference on intelligence research. Many enemies are quoted, calling him a racist, etc., but not a single friend or defender.
