Essentially, what quick 'tells' do men have that give away their mental weakness? It's hard not to be aware of the stunning frailty of a typical male, and I think a sharing of advice of quick methods of filtering weak men from those who are some combination of intelligent/rational/determined/whatever. In a very PC world, it's good to have some idea of with whom your real opinions can be shared, and those to whom you give your fake, likely-to-please opinions.

A quick example I have from last year: For some reason I was talking about a scholarship program this state had (I want to say Illinois?) where all in-state students got their tuition paid for if they met some basic academic standards. I pointed out how it's pretty stupid to give, say, a mechanical engineering student at U-Illinois (borderline first tier engineering school in the US for those not in the know) and a communications major at Northern Illinois the same reward and it makes no economic sense to pay for the education of middling students who can effortlessly be replaced at any time by other middling people.

But oh no. The guy's dad went to Northern Illinois. Instead of rationally noting that I wasn't making a personal slight at his father but instead identifying a plainly obvious fact-Northern Illinois students are not valuable- he immediately went to the emotional side of his brain and indignantly said "you'll never make as much as my dad did blah blah blah". No notion of the fact that it's not the early 70's where any college education is ultra-valuable just due to the dearth of qualified people outside of America, no mental energy given to the fact that on the whole the students at the school in question are marginal, no understanding that resources are limited and that not all causes are equal. Nothing but personalized emotion. I instantly knew to never share anything of value with him because he thinks like a woman, and I had no idea of this beforehand. Haven't talked to him since, but it would be valuable to get a read on others I do interact with.
