Misinformation Effect (false memory)
Human memory is not as good as people like to think. There are times when you are 100% confident in your memory of something and the reality is, your memory is wrong. This is often seen in eye witness testimony situations. How is it that 10 people witness a crime and when asked, there are 10 different versions of the crime? According to the misinformation effect, when we witness an event and then get some incorrect information about that event, we incorporate that incorrect information (misinformation) into our memory of the event. The result in an altered memory of the event. You may not want to believe this one, but it's true and we are all susceptible to it.
