Harsanyi's purification theorem shows that beliefs about mixed strategies reduce to beliefs about payoff perturbations, collapsing the distinction between strategic and probabilistic beliefs.

Probabilistic beliefs(epistemology (how we know things))
Beliefs about something that aren't certain—like thinking there's a 70% chance something is true rather than knowing it for sure.
Purification theorem(game theory concept)
Harsanyi's mathematical proof showing that certain random strategies in games can be explained as if players were just making very precise (non-random) choices based on information they couldn't quite perceive.
strategic beliefs(Contrasted with beliefs about conditional probability in the context of Selten's Horse)
Beliefs that concern only what players will do given a set of payoffs and game structures, as opposed to beliefs about the epistemic or probabilistic frameworks other players operate with.
