Page "Occam's razor" Paragraph 23

Put another way, any new, and even more complex theory can still possibly be true.

For example: If an individual makes supernatural claims that Leprechauns were responsible for breaking a vase, the simpler explanation would be that he is mistaken, but ongoing ad-hoc justifications ( e. g. " And, that's not me on film, they tampered with that too ") successfully prevent outright falsification.

This endless supply of elaborate competing explanations cannot be ruled out – but by using Occam's Razor.
