I assume that the effect of sex hormones, particularly on the development of neurological structure, would have some impact on behavior.
Yes, it does impact behavior, although each group (men and women) also vary in terms of each individual's personal hormone levels, and both men and women have some amount of hormones of the "other gender." So there are many caveats here, and any conclusions that can be drawn will still be broad generalizations. And also, gender behavior patterns stemming more from social influences will obviously vary from culture to culture.
The aggressive impact of testosterone vs the nurturing effects of estrogen are probably the large broadest "overlays" on behavior that spring to mind.
Keep things casual and speculative at the moment, I can throw out some observations:
- Male and female ENFJs seem similar.
- Male ENFPs seem more aggressive than the females and seem more likely to get mean/vicious when angry; female ENFPs can also be volatile but I see many more at the "softer emotive" end than males.
- Yes, INFJ males do seem colder/harder than INFJ females. The females seem to emote more positive emotion, probably through socialization but perhaps hormonal influences as well.
- I've seen "harder" ISFJ women than ISFJ men... but that could be blamed partly on the fact I have such a much larger sample size of female ISFJs. In a similar vein, ISTJ women can seem colder than other women, but they are still warmer than the men. Usually the men are amiable or they are stiff/cold, but I think the women are socialized to emote more positive feeling, again, where the men are not required to do so.
I need to go, but perhaps some other people would care to contribute in the meanwhile. There are lots of nuances on a topic like this.
