Where can I find background information about psychologist/psychometrician 
Arthur R. Jensen, as well as information on his updated arguments about 
Spearman's 'g' (more than is in his 1998 book "The g Factor," and Meile's 2002 
book "Intelligence, Race, and Genetics: Conversations with Arthur R. Jensen")?

Abeaujean, I hope you find this information helpful!  If you need additional 
information, please ask for Answer Clarification.  Thanks!

Here is some background on Arthur Jensen: 
Psychologist; born in San Diego, Calif. An educational psychologist at the 
University of California: Berkeley (1958), he concluded in an explosive Harvard 
Education Review article (1969) that on average whites are more intelligent 
than blacks; his subsequent report (1979) that intelligence tests are not race 
biased further stoked the controversy surrounding his work.

He teaches at Berkeley, here is his campus contact info, so that you could 
contact him personally:
