I bring out a coin; I tell you nothing, and ask you to guess what the probability of heads is. What do you guess?

Unless you have reason to believe I am trying to deceive you, it will be able 50% because you have a lot of knowledge from other contexts that tells you this is true.

The arrow is probably the other way round than you state -the brain probably isn't Bayesian; being Bayesian is modelled on how humans process and contextualise decisions.

I'm not even sure how a frequentist would construct a model to estimate an outcome with no observations.

The same way a Bayesian would, since it's a question about probabilities of hypothetical experiments, not about statistics. Or you go through decision theory instead of mucking about with half baked ideologies.

This is false.
