Regression Fallacy

Regression fallacy assumes that a situation has returned to normal due to corrective actions having been taken while the situation was abnormal. It does not take into consideration normal fluctuations. An example of this could be a business program failing and causing problems which is then cancelled. The return to "normal", which might be somewhat different from the original situation or a situation of "new normal" could fall into the category of regression fallacy. This is considered an informal fallacy.
