If a smart guy joins a seminary then joining a seminary is probably smart.

I think a better way to think about it is that humans in general just make so many mistakes and imperfect judgements. Smart people just do them slightly less. Smart people also typically have biases as well which affects their judgement, their basis are just more complicated than normal people. Like obviously being smart is an advantage for any decision, but saying if someone smart does something it must be smart makes no sense in a world where smart people usually can’t agree on what is right.
