UFO Witness Testimony Contamination Simulator

Watch a UFO sighting account spread and degrade witness to witness: adjust retelling rate, per-retelling contamination probability, witness count and cross-talk to see how the misinformation effect erodes testimony accuracy over generations.

A single eyewitness account of a UFO sighting is passed from person to person, and this simulator tracks exactly how it decays. Each witness holds a small set of remembered details — shape, colour, motion, timing and more — and every retelling carries a real chance that a detail silently drifts away from what actually happened, exactly as Elizabeth Loftus's misinformation-effect experiments describe. Turn cross-talk on to see contamination jump between witnesses who compare notes directly, not just down a single retelling chain, and watch average testimony accuracy fall as detail drift accumulates across generations.

⚙ Under the hood

Witness testimony degrades with each retelling, influenced by a contamination probability.
