intelligence is like a vertical jump, some people just got hops.
Some people don't have much of a superego, just giving into their id constantly. The worse offenders are the fats. The fats can't control the impulse to eat, they become atavistic, gorging on food and pleasure to the point of cankles.
Most people are a walking dunning-kruger unaware of their projective identification because that haven't recognized that at the core of our being is nothing, lack itself. Nothing can fill this lack because its lack itself and originates within. More food, more food until you can't buy normal socks anymore, till the nike symbol becomes a literally dash warping sock-time like a fat-hole.
