If you don't want stupid questions, choose your words more carefully. Loose talk might mislead atheists and we wouldn't want that, would we?
It wasn't loose talk, it was you playing semantics.
And, as far as I can see, S..'s explanation completely contradicts you.
Well, then one of us didn't understand his post, because I cannot see anything in there that contradicts my position.
Survival is a 'useful' goal, the tendency to believe in the supernatural can increase survival chances,
In some circumstances, only. In others it can decrease survival chances. The superstitions that form the basis for FGM for example, which increase maternal and infant mortality.
Also, you have overlooked the misfire part of the useful superstitions about ladders and whatnot. See this part of S's post...
an attempt to create order out of seeming randomness, which in itself can have some survival value in some circumstances
Its not the superstition itself that contains survival value, the superstition is a by product of our tendency to look for order, cause and effect, identifiable rules, etc.
you have no way to determine which supernatural beliefs might increase survival chances,
That's unnecessary in this day and age. We have more reasoned bases for safety rules now that we have stopped believing in witch doctors.
therefore you have no evidence for regarding any as 'weaknesses' or 'misfiring'.
There are actually evidential supports out there in the form of experiments on other species, and observations of our own species from psychology and anthropology. If you were really interested you would google around and find them easily enough.
