New Study Concludes Math Gender Gap Is Cultural, Not Biological
New submitter germansausage writes "A new study was published today in Notices of the American Mathematical Society, looking at data from 86 countries, to test the 'greater male variability hypothesis' as the primary reason for the scarcity of outstanding women mathematicians. It concludes that cultural and not biological factors are the chief causes (PDF) of the gap in math skills between men and women."
Just amazing, what statements you can make about such clear data. Many, many studies to date have shown that male and female abilities in mathematics are roughly the same. Nearly as many have shown support for a higher variance amongst males, meaning there are more stupid and more brilliant men. This has been (and is) used as the explanation for the predominance of men at the very top levels of STEM fields.
So...this paper claims "greater male variability...[is] largely [an] artifact of a complex variety of sociocultural factors".
Look at Figure 1.B. in the paper and read their discussion of it. With three only three exceptions - two of which are outliers for other reasons, all of their data supports the variability hypothesis. The same can be seen in Figure 1.C - with the same three exceptions, all of the variance ratios are above 1, with an average around 1.16.
In the end, their data plainly supports the same conclusions drawn by all of the other studies. The sincere desire to reach a PC conclusion apparently blinds the authors to the plain meaning of their own data.
Enjoy life! This is not a dress rehearsal.
As for biological factors, It seems to me the distribution curve for men is flatter than for women in most things. You get more insane/evil/retarded men than women. You also get more "ultra genius" men than women.
This is one of the hypotheses explored in the study. They find no support for it.
