Where do people actually change their minds — which venues, at what rate?
Rates per venue with denominators: mailing lists 3.0 per mille, forums 2.3, Hacker News 2.2, reddit comments 1.0 (H1 2025).
Methodology
scry_recipe('changed_my_mind') is a shared, measured stance instrument — a curated term-set with a false-positive profile — usable as a plain SQL predicate. Rate = countIf over count() inside a window: population measurement, not retrieval, and the denominator ships with the answer. Swap in hedging, gratitude, or a concept recipe; the shape is unchanged.
