The idea that there are only minor differences between the personality profiles of males and females should be rejected as based on inadequate methodology. (continue reading…)

Early in 2013, the Food and Drug Administration (FDA) ordered the makers of the well-known sleep aid Ambien (zolpidem) to cut their recommended dose in half-but only for women. In essence, the FDA was acknowledging that despite extensive testing prior to the drug’s release on the market, millions of women had been overdosing on Ambien for 20 years. On February 9, 2014, CBS’s 60 Minutes highlighted this fact-and sex differences in general-by powerfully asking two questions: Why did this happen, and are men and women treated equally in research and medicine?1

The answer to the first question is that the biomedical community has long operated on what is increasingly being viewed as a false assumption: that biological sex matters little, if at all, in most areas of medicine. The answer to the second question is no, today’s biomedical research establishment is not treating men and women equally. What are some of the key reasons for the biomedical community’s false assumption, and why is this situation now finally changing?  What are some of the seemingly endless controversies about sex differences in the brain generated by “anti-sex difference” investigators?  And what lies at the root of the resistance to sex differences research in the human brain?

This study focuses on the relative frequencies of various sexual activities and the ways in
which those activities are portrayed in homosexual and heterosexual pornographic films.
Many anti-pornography arguments are based on the alleged oppression and degradation
of women in pornography. Others (Salmon & Symons, 2001) have suggested that the
main focus of pornography is not about contempt for women and that if it was, gay
pornography should differ dramatically from heterosexual pornography. This paper tests
that hypothesis. Sixty films that ranked amongst the most popular heterosexual and
homosexual DVDs were examined with regard to the types of sexual activities that occur
and the interactions between the participants. We found few major differences in
pornography aimed at a homosexual versus heterosexual male audience, other than those
that reflect the different anatomy involved, and none that reflect an anti-female agenda.
