Invalidity
"Religious beliefs are irrational and invalid. They cannot be considered to be true. Their supernatural elements are superfluous, lacking real basis: therefore, Occam's Razor rejects them."
(Occam's Razor is a rational principle. For more rationality, see The Rational Belief.)"

...''Because you'll believe anything.''

ONCE upon a time, razors with multiple blades were a joke. The first broadcast of "Saturday Night Live" included a mock commercial for the "Triple Track," a three-bladed razor, featuring the slogan: "Because you'll believe anything."

Chris at Developing Intelligence has an interesting post on Why The Simplest Theory Is [Almost] Never The Right One, in which he suggests that Occam's Razor isn't a very useful principle in the life sciences, developmental psychology, or cognitive neuroscience. A heated and lively discussion ensues in the comments.

What is Occam's Razor?

Occam's razor (sometimes spelled Ockham's razor) is a principle attributed to the 14th-century English logician and Franciscan friar William of Ockham. The principle states that the explanation of any phenomenon should make as few assumptions as possible, eliminating, or "shaving off," those that make no difference in the observable predictions of the explanatory hypothesis or theory.
