Frequentist vs Bayesian statistics - a non-statisticians view

Abstract

People who by training end up dealing with probabilities ("statisticians") roughly fall into one of two camps. One is either a frequentist or a Bayesian. To a scientist, who needs to use probabilities to make sense of the real world, this division seems sometimes baffling. I will argue that science mostly deals with Bayesian questions. Yet the dominance of frequentist ideas in statistics points many scientists in the wrong statistical direction.
