Scoring or checking that would definitely be difficult unless the game had a syntax for hypotheses, something like drawing causal arrows between bubbles. But that would at the same time make it boring and unhelpful to make hypotheses. I guess it's not really game material.

I suppose you could have the hypotheses written by the designers and then have various characters espouse them over the course of the game. But that would make the exercise very minor and not worth it.

Soooo nevermind.
