Brain Makeover

submitted by: Science Cheerleader
The Science Cheerleader, Physics Professor James Trefil of George Mason University, and the Philadelphia 76ers want you to give it up for the key concepts in science that will help you be a “scientific literate,” pain-free! (Pssst: Only 7% of the adult American population are science literate*, and that includes all the scientists and engineers. (*Why Science?, Teachers College Press, 11/1/97.) To start your Brain Makeover, click on any one of Trefil's 18 Big Ideas to watch a 76er...

Foundations for Bayesian Updating

submitted by: dougramsey
We provide a simple characterization of updating rules that can be rationalized as Bayesian. Namely, we consider a general setting in which an agent observes finite sequences of signals and reports probabilistic predictions on the underlying state of the world. We study when such predictions are consistent with Bayesian updating, i.e., when does there exist some theory about the signal generation process that would be consistent with the agent behaving as a Bayesian updater. We show that the...
