'Men cleverer than women' claim
All that this particular research shows is that for the IQ test used, there is a slight variation in the success of those taking it. On average men scored 5 points more on this test. So what? I tried out several tests the other day and there was a variation of 15 points in my score depending on what test I did. When I took a general test in German I got 133 and I had done the same one earlier in English and got 126. I tried a culture-fair test and got 115 (and I couldn't even answer half the questions as it was very spatially-oriented). And I got 130 for a verbally-oriented test.
I guess these researchers have tested the results for statistical significance and concluded that they are significant, but even so I think all it shows is that men are good at passing IQ tests. All they were testing for were verbal and spatial skills, nothing about social or emotional skills. I think these men are just insecure about women's academic performance.
Men - know your limits.
