“People believe what they want to believe.” People who believe in UFO’s, who make that unwarranted leap from “Unidentified” to aliens from outer space, will see spaceships. Period.

Re: Deductive Reasoning. Very useful in math, but when used in day to day life, it is a fallacy (”a priori” thinking). Accepting an idea without sufficient proof, then deducing “facts” from it. The person who uses this kind of thinking usually “cherry picks” his facts, dismissing those that don’t agree with his theory.
