Public
Loftus and Palmer showed people films of car accidents, then asked how fast the cars were going. People asked about cars that "smashed" gave higher speed estimates than people asked about cars that "hit". A week later, the "smashed" group was more likely to report broken glass that was never in the film. Eyewitnesses are close to the event, but questions asked afterwards can reshape what they remember. Treat testimony as evidence of what someone recalls, and look for records that don't depend on memory.
