Humans operate on instinct too. What about the fight or flight response? I've seen a study on what female proportions are the most sexually attractive to males. Women with a 1:1.1 shoulder/hip ratio was the most attractive to from varying cultures, which would tend to lead one to believe that attractiveness is hard wired in the human brain, not a cultural construct.
Do you have to teach a baby how to feed? etc. etc. etc. You have to remember that humans are animals and were nothing more for about 1-2 million years, it's only in the last 100k year that we've risen above that.
I just did a literature search and posted any and all relevant papers, whether they agreed with my point of view or not. I also posted the ref. to the paper you post. It's never a good point to take one study as proof positive of anything. I don't discount your study at all, but I prefer a body of evidence since many times different studies give conflicting results.
If you give a female humans estrogens in the proper doses that will inhibit ovulation, if you give a male human test. it will increase aggression, over a broad spectrum tho, of course.
Not all AAS's cause aggression in equal amounts or at all in the case of winny(?), and I don't need a rat to tell me that either
