Logical fallacies are errors of reason that can occur in
inductive reasoning. Since inductive reasoning moves from the particular to the general, it is important to determine how much and what kind of evidence you need to make a valid argument. Failure to have proper evidence is linked to several kinds of logical fallacies.
Post hoc ergo propter hoc: Assuming that sequence indicates causality is the mistake made by this Latin-named fallacy. Translated, the name means "after, therefore caused by." An example is:
My cousin drank the town water and got leukemia. It must be the town water that caused her illness. The sequence of drinking town water and subsequently falling ill from leukemia does not in and of itself lead to a valid conclusion that the water was the causal agent in the illness. Thus, this is a cause and effect fallacy.
