Physicists have this nice saying: "Shut up and calculate".
Bayesianism, frequentism, who cares? "All models are wrong, but some are useful".
Bayesianism would be a footnote in history if it weren't for Markov Chain Monte Carlo, which allows you to perform estimations when Maximum Likelihood fails.
All those people who wax poetic about priors and expert knowledge and stuff, just keep away from them. You don't want to mix with that crowd.

- goatlover 5y ago> Physicists have this nice saying: "Shut up and calculate". Some, but not all. Some want to know what it is that makes it so we can calculate the probability of a measurement, or whether a black hole loses information. Some are/were quite philosophical, including Feynman, despite his protestations.
- credit_guy 5y agoNot some, all. Physicists earn their right to talk about deep foundational things after they first shut up and calculate. Those who are not able to calculate, don't get tenure.
