I read the thread fairly quickly, but I think my view probably repeats what a lot of others have said. Men and women are different. If they were absolutely equal then we would be asexual beings. I think that in general men tend to rely more on logic while women tend to rely more on emotion. I have probably made the wrong decision on many things and I am sure I will in the future, but I still tend to think, rightly or wrongly, logic is a better basis for decisions. This is not to say there aren't exceptions. There are women who are much better analytical thinkers than I am. Also I am aware of situations where emotional ability puts me at a severe disadvantage to someone who has is capable in that area.
Men are generally stronger than women. However, I feel that overall I'm superior to some men who are physically stronger than me. So that's no indicator. Edited to add this: Maybe this is why women are underrepresented in such job sectors as trash collection, landscaping(the people who are actually out mowing lawns and cutting and laying sod etc.), movers and construction ditch digging. I see them go for the architect job in construction, but not many going for the ditch digging part My wife saw a female taxi driver the other day. I've never seen one myself. We actually have a female domino's pizza delivery person. That was the first one I'd seen. Just a little observation. On the other hand I used to work part-time at night moving packages for Fed-Ex. Very physical work unloading trucks and loading planes with packages ranging up to 75 lbs. Officially you were supposed to get help if it weighed more than that. It took me 2 or 3 months before I got adjusted and that job got me into the best shape I ever was. More men than women there and many dragged their butts. But the women who pulled their weight were doing more than 90% of the men, I'd say. I knew one particular lady who worked a fulltime day job in a packing and loading job and then came out at night for the Fed-Ex job. She used to kick my butt when were unloading trucks.
Mentally, I've seen no evidence that men or women are more intelligent than each other. It just seems that certain groups are people are more interested in certain things. I went to school for electrical engineering. There are always programs to attract more women and minorities into engineering and into the software field. But I think the simple fact is that most of the women and African-Americans I have come into contact with had no interest even in the basic math and science it takes to build a foundation for those fields. I'm a black guy by the way. I love math and physics, and there were only a few other African-Americans in the engineering programs. And probably less than 20% of the students were women. Despite that, a woman graduated with the highest GPA in my electrical engineering class.
On the other hand I think there tends to be more women and African Americans in majors like communication or sociology. Those majors are traditionally thought as being softer. My fellow engineering students and I would sometimes crack on business majors. "Where does an F engineering student go?" "To the business building." Or did I hear something like that in a Dilbert cartoon. There was a much better women to men ratio in the business programs also. Anyway, that was our jovial perception, but perhaps a better view would have been to say that it was just a different area that women and blacks tended to like more.
