When Sowell writes,
“A recent national competition among high school students who create their own technological advances turned up an especially high share of such students winning recognition in the San Francisco Bay Area. A closer look showed that the great majority of these Bay Area students had Asian names.”
which specific competition is he referring to?
I honesty don’t know but here’s a link with an email contact link for Dr. Sowell if you wish to contact him.
