a quick background from wikipedia.

you can watch the 7-part series here. (not safe for work: nudity)

each part is approximately 40 minutes long; i recommend watching #1 (gender equality paradox), #5 (sex), and #7 (nature or nurture) since they are most relevant to this subreddit.

7 nature or nurture:

in this part, the interviewer interviews several social scientists, biologists, and medical experts in norway and elsewhere in the world. the social scientists want to push the idea that gender is a "social construct," but the majority of biologists and medical experts soundly reject such ideas. the way the social scientists argue for their positions is both hilarious and frightening. a young baby boy (victor) was born with an undeveloped penis and doctors and surgeons removed the penis and then the boy was raised as a girl (victoria). victor was not happy with the feminine clothes he had to wear or the girly activities he participated in. victor (as a girl) had no idea that he was born a boy -- this is a counterexample to the theory that boys and girls are raised to fit into traditional gender roles. the "gender researchers" interviewed simply ignored his case.

5 sex:

despite feminists' insistence that culture shapes sexuality, researchers found that sexual desires are the same cross-culturally: men want more variation compared to women. women have evolved to desire less sexual partners due to the biological differences (pregnancy is more burdensome to women); women also want commitment from men as a result. men aren't as picky as women.

when women were asked what they seek in relationships:

short-term: they wanted a man with a bad boy attitude, who has a tough and robust look, and good in bed.

long-term: a man who is considerate, a great personality, good provider, etc.

evolutionary explanation: if it's going to be a short-term relationship, women will shop for the best genes rather than the best provider.

they also go into genetic cuckoldry ("mama's baby, papa's maybe") and how uncertainty of pregnancy affects male psychology. one of the most important things men look for in women for long-term relationships is faithfulness. women who have a lot of casual sex are rejected due to fears of infidelity.
