It's a weak strategy. If you make an obvious error in many contexts you are very likely to (at best) invite a cascade of critique that otherwise would have been skipped.

It depends on who is on the other end. Against someone who isn't that intelligent, who prioritizes and really just wants to show their dominance, it can work great. Against a genuinely observant and intelligent perfectionist, it's the wrong move.

I've seen it done with alignment and spelling errors. The pointy haired boss feels superior and useful in their attention to detail, and everyone has their needs fulfilled.
