Did you ever know someone who could arrive at an incorrect conclusion and then go find data to support that conclusion?

This phenomenon is known as the Texas sharpshooter fallacy.

According to Wikipedia, this is a logical fallacy in which pieces of information that have no relationship to one another are interpreted or manipulated until they appear to. The name comes from a story about a Texan who fires several shots at the side of a barn, then paints a target centered on the hits and claims to be a sharpshooter.

Here's another example of a fallacy.

That is just flat out wrong, and I've heard too many people rationalizing and supporting that fallacy.

I know all the arguments.

Rich people don't want to give their money to a salesman.
