Brief correction. he did not say Genetic. He said there may be a real difference in performance between sexes.
The first is difficult to prove. The second is handily proven. In other words - no one as far as I know can demonstrate a genetic link, whereas the greater number of high performing (and also low performing) males is quite well documented.
re grades - I recently thumbed through the "Business Week Guide to US Colleges" - one of the criteria used was graduation % - Harvard was like 98%. One would think a more aggressive college actually weeding out the lower performers - (see Cornell Engineering School, for instance) would be considered a "better school" - but again - the strange judgement of people who make these ratings is evident.
Everyone has known for some time that the hardest thing about Harvard was getting in. After the Larry Summers thing, I would have to adjust that to "... getting in and not throwing up due to stench of PC lunacy."

One wonders if their reputation will ever weaken---or can the Leftist establishment hold it up indefinitely.
