Good Example of what I was talking about.... Just to clarify, I do think that science may support an a priori bias, the problem is when your a prior bias interferes with what the evidence leads to, and you are dismissing or cherry picking the evidence because of.

Science is the study of the natural world.  It literally doesn't deal with the supernatural by definition.  That's not an a priori bias.  That's just the nature of the inquiry.

And please, do give us an example where an a priori bias against the supernatural has interfered with a scientist's ability to follow the evidence. I'm sure we could all use a good laugh.
