It's worth knowing that what Jaynes calls "probability" everyone else calls "statistics."

Generally, "probability theory" means studying well-specified random models. In some sense this is frequentist, but in another sense the distinction does not apply. Whereas "statistics" is about subjective ignorance.

That terminology sounds strange to me.

I define statistics as a toolbox of methods to deal with uncertainty.

And simulation theory is kinda the opposite of statistics - whereas in statistics you deduce the distribution from sample data, in simulation you compute plausible sample data from a given distribution.
