Men's behavior is always excused because of HiGh TeStoSTeRonE but in actuality, testosterone does not cause aggression.

Testosterone causes status-seeking behavior.

In one study, researchers had participants decide how to split an amount of money between them. The first participant would propose how much each person would get, and the second participant would either accept or reject the offer.

Participants that were injected with testosterone would actually offer the second participant MORE money, not less. You would think the participants would become more aggressive and keep more of the money to themselves, but this is not what happened.

The researchers said the higher offers were more likely to be accepted, "thereby reducing bargaining conflicts and increasing the efficiency of social interactions"

There are several studies showing that testosterone increases COOPERATIVE behavior.

TLDR testosterone is not an excuse
