I ran into a discussion on the average IQ plot of students by gender ratio the other day. The plot is attached here and follow this link for the original post.
An interesting and obvious “fact” from this plot seems to be that the more women a major has, the lower average IQ the students from that major have; thus men are smarter than women. But, assuming that the statistics are accurate (which probably are not and have some kind of sampling bias), we should not forget that correlation is NOT causation.
For example, in an experiment conducted by Katherine Milkman, Module Akinola, and Dolly chugh (look at the New York Times report on this), they sent more than 6500 randomly selected professors from 259 American universities from fictional prospective students for Ph.D. program seeking. And it turned out that professors were more responsive to white male students than to female, black, Hispanic, Indian or Chinese students in almost EVERY discipline and across all types of universities. And that the lower the percentage of the minorities (including women) in a discipline, the less responsive the professors to the minorities were. This could be one of the potential reasons for the less representative of women in technology and science.
Also, since 1970, the percentage of women in STEM (science, technology, engineering, mathematics) has actually been increasing from 7% to 26% in 2011 according to U.S. Census Bureau statistics. The situation is continuously changing with the liberation of women going on.
In conclusion, this plot is worth discussing but DOES NOT mean that men are smarter than women. Let’s continue striving for making our higher education more inclusive and prejudice-free.
