A comment in Science

A well-stated hypothesis describes a state of nature. It is either true or not true, not subject to probability. The phrase “probability the hypothesis is true” is meaningless. One can only say, “likelihood that the observed data came from a population characterized by the hypothesis.”

I only post, because I seem to spend my life trying to argue that the dismal null hypothesis is a tool for doing one type of statistics, and has a limited role in science. It has little to do with what we mean by a scientific hypothesis. There are not an infinite number of scientific hypotheses: there is a not a probability distribution in the  way we use this term in statistics.
