What is the significant difference between male psychology and the female in the human species?

I'll offer a little proposal and then addendum of possible problems witch keep it as speculative, I'm also writing quick before the places closes.

Masculine behavior is more significantly determined by the internalized perception of social position and relevance than is female behavior.
As such, this predetermination allows a degree of freedom from the insecurities of choice and decision making. Whereas in the female behavior is less predetermined. This freedom engenders a state of insecurity that the female psyche responds to with a reaction formation that increases "her" need for social position, relation or relevance.
This is all a matter of degrees, such as, with this weather, at twenty five degrees Farenhite the pipes won't freeze but at twenty four they will. But, depending, on location, wind, humidity, did you leave the tap dripping, effectiveness of insulation, etc. etc..

So, probably the first question is: (not counting if I'm writing clearly enough) Do the observations of other primates and mammals apply or relate directly to human behavior?
Do phenomenon of individual personality adaptations such as the defence of reaction formation apply to generalized statements? Etc, etc.
So anyway now that we know this; What do men want?
