And One Eyed Myra, the queen of the galley who trained the ostrich and the camels
You’re mugged by a man with a patch over one eye. You describe him and his distinctive appearance to the police. They locate a one-eyed suspect and present him to you in a video line-up with five innocent “foils”. If this suspect is the only person in the line-up with one eye, prior research shows you’re highly likely to pick him out even if, in all other respects, he actually bears little resemblance to your mugger. So the challenge is: How to make police line-ups fairer for suspects who have an unusual distinguishing feature?
Police in the USA and UK currently use two strategies - one is to conceal the suspect’s distinguishing feature (and tell the witness they’ve done so); the other is to use make-up, theatrical props or Photoshop to adorn the other members of the line-up with the same distinctive feature. Now Theodora Zarkadi and her colleagues have compared both approaches and found the fairer method is to replicate the unusual feature.
