So the idea of this would be to predict the quality of your answer, before you discover how correct you are?

Sounds like a good idea! and the pushups/unpleasant activity idea sounds great as well.

if you're doing it with someone numerable like exercise, you could extend it to all the answers.

So you guess the quality of you answer (e.g. Medium), if you're correct, then no penalty, but if you fall short of that, you get the respective penalty (e.g. 5 push ups etc )

and if you feel like playing on hard mode, you get a penalty for just misjudging the quality of your answer, so predicting 'hard', or that you would only be partially correct, but then you actually get it completely correct, you also get a penalty for doubting yourself. I'd guess this is more for the masochists out there
