I really like this idea!

You can find it in all sorts of places. Here's one in video games: there are a lot of League of Legends videos by a channel called "Skill Capped" that each claim to have "one neat rule" or "5 mistakes to watch out for" to help you get better at the game. The only problem? The "one rule" is something like "don't do this thing unless you know that there's an 80% chance that it'll work" - and that's the hard part, that the video does nothing to help with.

I think that this is another flavor of "insight porn" where the video portrays itself as boiling down something hard into a simple insight - yet that insight is tautological, not useful, and/or skips the hard part.
