what exactly is the problem?
A hypothesis, as I understand it, is nothing more than a proposition that if X is true, Y should result. It is basically a logic statement (but obviously more than just a logic statement).
When you remove the objective evidence from a hypothesis, you are left with a logic statement. Formal logic is entirely independent of objective evidence.
What of the equation:
(objective evidence) = (hypothesis) - (logic)?
If you remove all the logic from a hypothesis, all you are left with are observations of reality, the objective evidence.
Seems to hold up to me.
