The greatest theory of all time? The more I learn about the Bayesian brain, the more it seems to me that the theory of predictive processing is about as important for neuroscience as the theory of evolution is for biology, and that Bayes' law is about as important for cognitive science as the Schrödinger equation is for physics. That is quite an ambitious statement: if our brains really are Bayesian, which is to say that predictive processing is the fundamental principle of cognition, it would … [Read more...]
