Because if it was, then surely any specie that would have evolved Bayesianism would have taken over the world instead of us.
Humans evolved a step towards being capable of Bayesian reasoning and we completely overthrew the natural order in an evolutionary instant. We should not expect to see close approximations of Bayesian thinking (combined with typical goal seeking behaviour) evolve because when a species gets vaguely close it becomes better at optimising than evolution is!
