"post hoc" (Latin)

What does the Latin term post hoc mean?

"Post hoc" is a Latin term that translates to "after this" or "afterward" in English. It refers to a logical fallacy known as "post hoc ergo propter hoc," which means "after this, therefore because of this." The fallacy occurs when one assumes that a preceding event or action is the cause of a subsequent event or outcome solely based on the temporal sequence, without considering other possible factors or evidence.
