Like I believe higher testosterone tends to turn on thinking independently so that the ingroups and outgroups are identified in a way more conducive to survival, and such that behavior can be handled rationally rather than with callous dismissal and hostility or blind trust. Being less of a dick and not trusting but verifying. Courage to face the unknown can come from testosterone or from a natural curiosity in one's temperament and values, and is a moral trait that is ultimately much more advantageous for the group and for individual prosperity, I would think.
