"You postulate,develop a theory, or a belief, and then you look for evidence to support it."

No, you look at the evidence, develop a hypothesis and then test it. Looking for evidence to support a belief is not science, it's faith.

Opinions are not equal, and this has to be taken into account when discussing any given subject. I certainly have an opinion on why my car does this funny thing when the turbo on the diesel fails to kick in sometimes, but in truth I have no bloody idea at all and my opinion, compared to that of a mechanic, is actually worthless and should be ignored. My observations might prove useful though, as evidence of the fault and it's nature.
