Fallacy of assumption of causality based on sequence of events
This article is about the informal fallacy. For the West Wing episode, see Post Hoc, Ergo Propter Hoc (The West Wing). For other uses, see Post hoc.
Post hoc ergo propter hoc (Latin: 'after this, therefore because of this') is an informal fallacy that states: "Since event Y followed event X, event Y must have been caused by event X." It is often shortened simply to post hoc fallacy. A logical fallacy of the questionable cause variety, it is subtly different from the fallacy cum hoc ergo propter hoc ('with this, therefore because of this'), in which two events occur simultaneously or the chronological ordering is insignificant or unknown. Post hoc is a logical fallacy in which one event seems to be the cause of a later event because it occurred earlier.[1]
Post hoc is a particularly tempting error because correlation sometimes appears to suggest causality. The fallacy lies in a conclusion based solely on the order of events, rather than taking into account other factors potentially responsible for the result that might rule out the connection.[2]
A simple example is "The rooster crows immediately before sunrise; therefore the rooster causes the sun to rise."[3]
