Post hoc ergo propter hoc, Latin for "after this, therefore because (on account) of this", is a logical fallacy (of the questionable cause variety) which states, "Since that event followe this one, that event must have been caused by this one." It is often shortened to simply post hoc and is also sometimes referred to as false cause, coincidental correlation or correlation not causation. It is subtly different from the fallacy cum hoc ergo propter hoc, in which the chronological ordering of a correlation is insignificant.
