Ok, that's a good point that negates the bet. But we do not switch on beliefs. — Relativist

That is true. But our beliefs are not the issue. The reality is the issue... our beliefs may be false, totally false, and we wouldn't know it. There is no assurance either way.

However, and here I am arguing against myself, if you act according to your beliefs, at least you get the satisfaction for the time being that you are doing the right thing. That is worth something, too.
