Extraordinary Claims Require Extraordinary Evidence

Jorm: Sure, you're right, statistical analysis would be a little different. It's never possible anyway to prove a theory correct with 100% certainty, only that it appears true beyond reasonable doubt.

In the case of ESP and bullshit like that, the claim would be something like the probability of guessing which card the person is holding is higher than just guessing. I agree it's not the same as making a specific prediction. Good point!

It still has to be testable and falsifiable though, although the parameters for success have to be carefully chosen like you say.

RR: Can you give us one single example to indicate what the point of this thread is? Because I still don't get it.

Are you saying if several people said they saw a unicorn, you'd believe them?
