Right, try tabooing "prediction."

The only way I can think of to completely divest the practice of predicting from any talk of truth and belief, is to consider it as a wholly mechanical procedure for producing betting odds. (On the understanding that the agent placing bets just does so unthinkingly & doesn't worry themselves with questions like "what if this event does not come to pass?" which end up requiring truth/belief vocabulary.)

Otherwise, the whole point of predictions is to form beliefs about what will be true in the future... avoiding that vocabulary is a huge pain, in contrast with the advantage (avoiding a few, mostly sophomoric, philosophical objections to truth).
