The human brain is the best Bayesian model builder that evolution has yet devised. A good place to start assessing its weaknesses is to observe your own brain messing up. This shouldn't be hard to do.
- madhadron 7y agoWhy do you think that the human brain is Bayesian?
- c2471 7y agoI 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.
- madhadron 7y ago> 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. > being Bayesian is modelled on how humans process and contextualise decisions. This is false.
