> Is there a name for this sort of statistical error? Because it's everywhere. Yes. It's called not understanding Bayes' theorem. Bayes' theorem is precisely about how the probability of "B, given A" (P[B|A]) relates to the probability of "A, given B" (P[A|B]). In our case, that would be "rich, given love for endurance sports" =/= "love for endurance sports, given rich". It is immediately obvious from Bayes' equation that the two are, in general, not the same.
