My new job is in a den of Bayesians! This sort of philosophical trouble is something I avoided for years when I worked on random graphs. In combinatorial probability, I just said “assume the axioms of probability” and got to look for all the interesting facts that follow logically. People want these probability calculations to say something about the “real world”? That’s not my thing; it’s up to them to go from math to science. Well, now it is my problem.
