Built to be fair
Blind & shuffled
Titles and sources stay hidden until you vote. Each listener gets a random A/B placement, fixed on reload.
Same instrument, same volume
Every score is engraved and played by one sampled piano at one fixed touch, loudness-matched, so production can't win the vote.
Full listens count
A vote counts as a full listen only if you heard at least 90% of both pieces. Partial listens are kept, but apart.
Uncertainty, always
Rankings use a Bradley–Terry model with 95% bootstrap intervals and rank ranges, and stay provisional under 30 judgments.
Per-task results
Every brief's head-to-head is published on its own, so one overall number never hides where a piece won.
Neither ≠ tie
“Both equal” and “neither is good” are different answers. Rejections are reported separately rather than mixed into the ranking.
