False analogy - Definition and Overview

False analogy is a logical fallacy applying to inductive arguments.

In an analogy two concepts, objects, or events proposed to be similar in nature (A and B) are shown to have some common relationship with another property. The premise is that A has property X, and thus B must also have property X (due to the assumed similarity of A and B). Unfortunately, in the case of a false analogy, A and B are only superficially similar (if that) and are different in some fundamental way which influences their relationship with property X.
