Professor Rushton's article today says
The discussion of race and intelligence is being actively repressed on campuses as I write these words.
We've had several articles on this tendency in different forms, the most recent is Professor Frank Ellis, of the University of Leeds, who was suspended for saying to a student newspaper that there is a "persistent gap" in IQ levels.
That is, he was suspended for saying what Charles Murray recently said in Commentary Magazine, and in the Wall Street Journal. Or he was suspended for saying what 52 scientists said in a signed advertisement, Mainstream Science on Intelligence, also in the Wall Street Journal.
