I feel like there is a big overlap between being against common sense and believing you are better / more intelligent (more "rational" perhaps?) than other people. For me, at least, gaining a bit of humility / being a bit more down-to-earth about being a person like everyone else has made me significantly more likely to just pick the common sense path as a default.

The problem with "secret esoteric hacks/techniques" is that other people are not NPCs and are in fact also trying to achieve their goals, and for any goal you can imagine, there are a million people who have put in way more effort into figuring out the optimal path.

If there's a secret method of becoming good at an instrument quickly, why don't music schools teach that? If there's an obscure way to run a 4 hour marathon without much training, why doesn't every training plan include that? The common sense approach is usually right on the inflection point of the 80/20 rule, where you get the easy, simple way to get decent results.

Of course, there are sometimes real constraints (i.e. popular apps like Duolingo are bad for learning a language, because most people who use it are not serious about becoming fluent and not willing to put in time) but even then, the reasonably effective answer is usually 1 layer below the surface (learn the basics through a textbook/course/online material, then just use the language a lot and actively study new vocab/grammar/concepts), not in some obscure rabbit hole.
