This also includes your understanding of said knowledge, for convenience.

You do not get to choose what part of bad knowledge slips through, could be a dark secret you don’t want slipped out, could be something you want to take to your grave, could be that you’re an orphan, or you hate oranges. It varies how bad it is at random.
If it doesn’t bother you, then it won’t pass through.

Bright side, you can study heavily on how a washing machine works, go up to a random person, then just shove all of it in their head and walk away. Or if you’re teaching someone how a game works or the knowledge of music theory or the lore of a tv show you no longer have to teach them, and nerd out to them without them getting lost.
You could technically be the best teacher to ever exist and never have to teach once.
Also, this is a freebie for anyone that doesn’t regret their past already.
It might be beneficial too considering you can train yourself to not be fazed anymore.
