Factor C

When correlation doesn't equal causation, people tend to make the mistake of skipping from factor A to B. That missing third ever-so-absent variable of the logic chain is C.

"A is correlated with B. Therefore A leads to B."

No, both "A" and "B" are related to "C". It's Factor C.

Person 2: "Factor C: Smoking... Are you actually retarded?"
