You don't need evidence for a null hypothesis, rather you need evidence to logically move away from it according to my understanding.Yeah, but that is not obejctive. In effect it is not different than a belief in God, because they are both subjective and without evidence.
Eg the null hypothesis would be the glass is empty unless you find evidence of water or other substance in it.
What you are effectively trying to sell me in my view is like saying "the glass is full" is equivalent to saying "the glass is empty" when we have no evidence of any substance in the glass.
Sorry but I just dont buy your false equivalence in my view.
