PriorForge
Every game starts at 5.5 (ages 15–18): adjust the block of dummy votes, add real ratings, and watch a Bayesian average pull a small crowd toward the prior — the exact shrinkage formula behind a board-game leaderboard. Only volume overcomes the prior. Deterministic, on-device; text-forward.
#5b6cc4 Distributed-narrative cast
Meet the cast
PriorForge's adapted-DN-S cast (ages 15–18, realistic statistician personas — no mascots, per R-OLDER-TEEN-DN-ADAPTED) each embody one idea behind the Prior Rule; mentor Sol asks what a rating with only three votes really tells you.
Priya
the prior — every game starts at 5.5 before any real vote
Bayard
the shrinkage average — blends the prior with the evidence (the Bayesian mean)
Vera
the volume rule — it is VOLUME, not a loud few, that overcomes the prior
Dunna
the dummy-count — counts the prior block and how many real votes it takes to move it
Sol
(Mentor) — asks what a three-vote rating really tells you
