The Loftus and Palmer Eyewitness Testimony wanted to prove wether people's memory is malleable.
They used loaded questions to distort the memory of the subjects that were shown a video of a car crash, and when asked to state the approximate speed of the cars, the answers varied depending on how the question was asked.
This study helps prove that loaded questions, or influenced by misled information, people change what they have percieved and creates something new that combines facts with imagination in order to be in agreeance with the false information.
