If these guys are so smart and know everything about women, why they are single? (Do not include physical appearance as a factor)
Apart from the mangling of grammar in the "why they are", this is actually a reasonable question. But it's also one with a lot of nuances, and the question implies there's a simpler answer than there is.
First, in terms of IQ, I consider most people on the LS forum to be average or slightly above.
However, if we're talking about "smart"/intelligence, that's a bit more involved.
I subscribe to the MBTI model of cognition, so I view intelligence more as competencies in the 4 main areas of information processing: S,N,T,F.
IQ tests focus on measuring competency in N and T - inuition and thinking/logic. This is probably the most suitable set of functions to focus on for an overall picture of "intelligence", because they're what most people associate as intelligence. Intuition deals with pattern recognition, abstraction, symbolism etc. Of course, there's extraverted and introverted orientations of each function; Ne is "joining the dots", Ni is "filling in the blanks" etc. So logic combined with N is the obvious "intellectual" combination.
I'm an INTP so I do well in these areas, but I recognise I have weaknesses in the other areas. S is dealing with sensory information, F deals with valuations, emotional models etc. Fe is social norms, external harmony, serving others, sympathy. Fi is personal valuation - being in tune with what you believe, knowing what you want, deciding what is morally right or wrong, empathy.
I'm actually not bad on the F, but I don't value it much for determining truth (Ti). Hence I'll sometimes deliberately say something discordant to social harmony because I dislike the need for social harmony overwhelming more important aspects of free expression, so it's to "keep it in check" as such lol. People here then assume that I am just oblivious to the social rule I broke.
Anyway, I suck pretty badly on S. If you asked me what colour the wallpaper in my house is, I probably couldn't answer. Actually, I can't remember if we have wallpaper, or if it's just painted.
So you get ISFP artist types who can draw these brilliant paintings and all and express their feelings in a sensory way, but they're not likely to understand abstraction or objective logic. Are they stupid? Well, that's why I refer to IQ as a slightly separate thing to intelligence.
I'll post some more on this, but I only post here when I'm bored in work, and I need to get some work done.
Why do you assume woman have an easy time dating or entering into a relationship?
I have an actual diagnosed anxiety disorder, and the idea that there's nothing they could do is patently false. There are tons of therapies for anxiety disorders especially social anxiety.
If they have a disorder, it may be difficult for them. I never said it's always easy for them to enter into a relationship or date, just that the difficulty comes from within. Externally, things are always made easy, and it's easier to deal with the anxiety disorders because there's less pressure on women to appear confident or strong.
