I agree with this. I quibble with the wording "enjoy" thinking. It's probably also true, but it's not always the enjoyment of it, but a general propensity to overthink or dig into the weeds more, with the resulting less actual doing.

And if you dig into the weeds enough, you can find alternatives and counterarguments which can lead to analysis paralysis.

I add that most problems are solved, assuming possessing the average (maybe even sub-average) intelligence needed to execute on them.

Think about weight loss: it's a solved problem, except in extremely rare cases of particular pathologies. Or think about being more attractive to the people we want to attract.

But you can't help but notice that the smartest people are the ones who invoke the laws of thermodynamics and the problems that arise from them, that a calorie is not a calorie in humans, for example, instead of simply eating less, as many less intelligent people intuitively know they should do, and do.

The most intelligent are those who refer to the findings of evolutionary biology, or to largely irrelevant social trends and mores, when pondering why they cannot get laid, instead of working to be more assertive, confident, outgoing, and fit, as the less intelligent are more likely to do, without thinking about it too much.

Or the endless conversations and debates, mostly online because in real life basically nobody cares, about God and religion and atheism, leading, as usual, to nowhere, while the less intelligent intuitively believe or not and that works for them.

As usual, there are selection effects at play, and we notice what we want to notice, ignoring, for the most part, other portions of the distribution of outcomes.

Nowadays, it is fashionable to say "you can just do things". And what some of the intelligent people miss is that they can just be happy. "But how can I be happy if nobody looks at me?" -- See above.
