Social instinct feels like quicksand. It's everywhere you look, and you can't possibly ever keep up with it, you just feel your position and relevance getting lower and lower with each passing glance. This guy's smarter than me, he dresses better, he has a girlfriend, he has a better smile, he has better taste, he sounds better than me, he isn't bowlegged, etc. Social-lasts have tunnel vision.
Often times I can suppress my reaction to the information I receive through it, since I'm not always impressed by my immediate social environment I'm in, but it eventually becomes a source of insurmountable insecurity. Even the supermarket bagboy becomes a source of envy.
