Human memory and human judgment can not be trusted. Doctored video caused people to believe they saw something they never saw.
Associate Professor Dr Kimberley Wade from the Department of Psychology led an experiment to see whether exposure to fabricated footage of an event could induce individuals to accuse another person of doing something they never did.
In the study, published in Applied Cognitive Psychology, Dr Wade found that almost 50% of people shown fake footage of an event they witnessed first hand were prepared to believe the video version rather than what they actually saw.
Scary thought: You get arrested for something you didn't do and then humans are called to testify as witnesses. Not Vulcans, oh no. Lowly, flawed, mistaken, gullible, foolish humans. The very thought is enough to make me ill. Lesson to take home: Innocent people should move to planet Vulcan lest they get convicted of crimes they didn't do.
You can't trust half the eyewitnesses.
In a game involving the use of fake money participants were deceived into believing that a person sitting next to them cheated. Shown a doctored video people were willing to claim they saw the cheating when it supposedly first occurred - even though the cheating never happened.
One third of the subjects were told that the person sat next to them was suspected of cheating. Another third were told the person had been caught on camera cheating, and the remaining group were actually shown the fake video footage. All subjects were then asked to sign a statement only if they had seen the cheating take place.
Nearly 40% of the participants who had seen the doctored video complied. Another 10% of the group signed when asked a second time by the researchers. Only 10% of those who were told the incident had been caught on film but were not shown the video agreed to sign, and about 5% of the control group who were just told about the cheating signed the statement.
Think about that. 5% didn't even need to see doctored video to agree to something they never saw.
