A and B are correlated if P(A ∩ B) != P(A) * P(B).

The idea is that you'd represent the prior using a data structure which allows you to easily determine which beliefs are correlated with a given evidence. I'm not an expert here, but I think this is what Bayesian networks are all about.

Considering all the different combinations of things you might condition on, the task does not sound trivial.
