Policing: Placing people who do NOT look the same in line-ups can improve accuracy by 10 per cent
US and UK researchers recruited 19,732 volunteers to play the role of eyewitness Each participant was shown a video of a faked crime, followed by a photo line-up The team tried line-ups of people that were more and less similar to the suspect Less similar line-ups were found to improve the accurate detection of the perp. Yet they did not increase false positives in line-ups with just innocent suspects
