I read somewhere that claimed females initiate flight defends more than males, who tend to initiate fight more, that is it is claimed males will attack more than females when frightened.
I believe the source was probably a Wilie article of the amygdala itself. I did not check the sources and can not manage to now, but what I want to know is if the claims have more of a biological backing rather than sociological. Since that's hard to determine with the abstraction of gender roles affecting many people, only a specific situation or seeping analysis may answer.
But strictly concerning the amygdala between male and female humans up to this point and as far back as possibly estimated, is the structure really as different as believed? That is do females really run more than fight by brain structure? Because I know some girls who do attack when scared, not just run, I.e. a burglary, prank, etc.
