I've learned that the more intelligent you are the more models you know and the more trust you place in them being actual reality vs just being models. This leads to overconfidence in things being a certain way so when life calls for flexibility, your rigidity will make you suffer. Cynicism develops from this rigidity.
Additionally, the more intelligent you are the more skilled you become at thinking about things logically. An intelligent person can convince themselves of anything using logic without realizing that all logic depends on unproven axioms and assumptions. Combined with cynicism, logic leads to a negative outlook on life that is hard to shake off.
