I recall reading that ~30% of humans have evidence of toxoplasmosis. But, it is unclear whether that is harming their intelligence. Statistically, cat owners have higher IQ than dog owners (pls do not shoot the messenger unless you want to provide further evidence of the validity of this observation).

Sure, I'll bite: there is no such thing as a sufficiently powered survey of validated tested IQ with "dog owner" and "cat owner" in the cross-tabs.
