Interactive Experiments

Each experiment below is a study from the lab, rebuilt so you can do it yourself: the same recordings, words and rhythms our participants met, and at the end your result next to theirs. The last page replays a published experiment on how opinions spread through networks of people and AI.

Practice mode Nothing you do here is recorded or sent anywhere yet. We plan to open these as citizen-science studies once our ethics amendment is approved. How taking part will work

• Experiment | GlobalTap Tap along with the crowd Tap to a candombe recording as GlobalTap participants did, judge their beats against the expert's, then see where you fall among them.
• Experiment | rhythm priors Rhythm telephone Reproduce a random rhythm, then reproduce your reproduction. Watch it drift toward the rhythms you expect.
• Experiment | Gibbs sampling What colour is "lavender"? Find the colour of a word one slider at a time, the way a Gibbs sampler explores a space.
• Experiment | consonance Stretch the octave Rate chords made of ordinary, stretched and gamelan tones, and watch the sweet spots move.
• Explainer | opinion diffusion Watch opinions spread Replay how statements changed in networks of humans, AI agents, or both, and paint your own.

Why these methods

Many of our experiments ask people to do something simple, such as tap along, adjust a slider or rewrite a sentence. Pooled across many people, or passed from one person to the next, these small acts reveal shared perceptual and cultural structure: the beat a crowd hears, the rhythms a culture expects, the colour a word evokes, the intervals that sound pleasant, or how opinions spread through a network. Most of these studies run on PsyNet, our framework for large online experiments.
