Post Hoc Ergo Propter Hoc
Translation: “After this, therefore because of this” ( Latin )
The Post Hoc Fallacy is committed whenever one reasons to a causal conclusion based solely on the supposed cause preceding its “effect”. Of course, it is a necessary condition of causation that the cause precede the effect, but it is not a sufficient condition. Thus, post hoc evidence may suggest the hypothesis of a causal relationship, which then requires further testing, but it is never sufficient evidence on its own.
