John Rushton is either very brave or very foolish. He has published a study which finds that men, on average, are smarter than women. This is one of those things that men have tacitly believed for, well, forever, but gallantry forbade them from voicing. Gallantry and an instinct for self-preservation.
Now Mr. Rushton, following the lead of academic kamikazis like Charles Murray and Lawrence Summers, rushes in where angels fear to tread.
Prof. Rushton also claims that just as women prefer men as mates who are taller than they, they also prefer men who are smarter than they. If so, many of them are no doubt disappointed.
In any event, the news report on this study is interesting. You can read it here. Feel free to pass it along to the special woman in your life.
