In the 1890s Our boy Sigmund did something truly groundbreaking: he decided that in order to study the origins of hysteria maybe he should try talking to and listening (!!!) to women diagnosed with it. When he started listening he found that nearly all of them spoke of CSA and SA by family members and those close to them.

Freud wrote it in the Aetiology of Hysteria. Only one year later he took it all back. Freud didnt want to face the fact that all these fancy pants people in Vienna were doing this to their own children.

So of course Freud decided all the women were lying and never listened to a woman again. What a man of science!
