I suppose this is why the comparison with Duolingo came to mind: teaching rationality is akin to teaching a whole language. We need lots of aspects of it, not just one.
Also (now I’m just introducing another thing here), ideally it would be in a style that is as friendly and non-threatening as possible—again, like Duolingo’s vibe—though obviously it couldn’t be as entirely neutral as learning a language. To be effective, it would need to leave learners feeling supported rather than shamed.
Again I think of HPMOR as a great example of all of this: it covers lots of different rationality skills and has a reader-friendly vibe.
The app’s hook might be something like “Learn to think like a scientist” or “level up your decision making skills” or “hack your own brain.” (lol, idk)
But to answer your question, if I had to pick one rationality skill that seemed most important to me personally, the one that comes to mind seems like a meta-rationality skill, which working on lots of other various rationality skills would also serve: building the habit—through training/practice—of noticing, questioning, and testing one’s beliefs.
