If one person—say, a dominant personality—injects into the conversation an incorrect recollection or ‘distorted memory’ that others in the group do not remember, they tend to take the other person’s word for it. As one recent study has shown, ‘The misinformation implanted by one person comes to be shared by the group as a whole. In other words, a collective memory could become formed around misinformation. Misinformation shared by one person may be adopted by the rest.’
