I discovered just how cautious scholars in this field can be when I was invited to attend a two-day conference on intelligence at University College London by the academic and journalist James Thompson earlier this year. Attendees were only told the venue at the last minute—an anonymous antechamber at the end of a long corridor called ‘Lecture Room 22’– and asked not to share the information with anyone else. One of those present, on discovering I was a journalist, pleaded with me not to write about the fact that he was there—he didn’t want his colleagues to find out. It was like a meeting of Charter 77 in Václav Havel’s flat in Prague in the 1970s. But these precautions were not unreasonable, considering the reaction that any reference to between-group differences in IQ provokes.This is in between a discussion of the harassment of psychologist Linda Gottfredson in the 90s and what happened to James Watson in 2007. Now it's happening to Toby Young.2017 Constance Holden Memorial Address: Liberal Creationism [PDF]
