Not playing games at all. I don't believe in default positions. I am legitimately interested in how you know not only that there is a default position, but what it happens to be.
I think it is meaningless to talk about beliefs and positions before people are capable of having them.
And once people are capable of having them, I think there would a myriad of "default positions" based upon individual personality, inclinations, talents, environment, etc.
FWIW, from what I've gathered from reading and listening to stuff from various psychological researchers, it seems that we're born with a tendency to infer agency and deliberate purpose in just about everything, but without any good ideas about what agency (or whether there would only be one agency) behind things. All in all, I'd say that the evidence suggests that our psychological default position is a sort of rudimentary animism that probably couldn't be considered actual theism.
However, this is different from the idea of a philosophical default position. When it comes to that, there are three possibilities for dealing with claims without evidence (or that don't have sufficient evidence):
- tentatively accept all of them. This isn't viable, since it would mean accepting conflicting claims simultaneously.
- tentatively accept some while rejecting others. This one is untenable too, since it's arbitrary (it has to be, since we're talking about claims with insufficient evidence to judge them).
- tentatively reject all of them. This one is the only strategy that doesn't create logical problems.
