>Smart people are exceptionally good at over-justifying, over-explaining, over-rationalizing.

What's that based on? Couldn't it be the other way round? Or simply untrue? Overthink by definition is suboptimal which doesn't sound very smart. If intelligence is defined in any way to include problem solving, a smart person should be able to solve the problem of finding the right amount of thinking to do on a particular topic, no?
