A smash or a hit?Researchers asked 150 subjects to recall the details of a car accident they watched on video. Fifty subjects were randomly assigned to be asked, โAbout how fast were the cars going when they smashed into each other?โ For another 50 randomly assigned subjects, the words โsmashed intoโ were replaced with โhit.โ The remaining 50 subjectsโthe control groupโwere not asked to estimate speed. A week later, all subjects were asked if they saw any broken glass at the accident (there wasnโt any). The table shows each groupโs response to the broken glass question.
