A logical fallacy in induction where an analogy is used beyond the point where it breaks down. Any analogy has this potential problem, so be careful.

Example: "The brain is like a computer, so an operation to implant RAM into my brain will give me more memory."

To prove the False Analogy, show that the objects in the analogy are different in such a way that causes it to break down.

Occurs when two things that are not truly similar are compared as if they were the same.

A popular idiom used to indicate a false analogy is the term "Comparing apples and oranges".

Here is an excellent example I found: "Employees are like nails. Just as nails must be hit in the head in order to make them work, so must employees."
