Misleading information and questioning- If a question is misleading then the information that answers the question will also be misleading as they would give the answer for what they were asked not what they saw, e.g. if a robber drove off in a black BMW and the inspector asked what colour was the van, the witness would get confused and due to them mainly focusing on the robber they would not register what the getaway vehicle was. This would then lead them to thinking that it was a van instead of a black BMW and give false information. The study actually consists of two laboratory experiments.
