Previous research suggests that co-witness influence is heavily dependent on how eyewitnesses perceive the source of information, with perceived credibility, authority and memory accuracy identified as significant predictors. However, very little research has directly investigated the effects of perceived intelligence on co-witness influence. The present study used confederates to expose participants (N = 182) to misinformation about a witnessed event, prior to collecting their statements. Participants were paired up with a confederate who was presented as either a PhD student (high intelligence), police officer (high authority), neutral (no information provided); or completed the study individually (control). Results found that participants were significantly more likely to blame the wrong person for the crime if it had been suggested to them by a police officer or PhD student. Implications of the findings suggest that the characteristics and perceptions of co-witnesses can moderate the risks of statement contamination.
