Brief description The traditional police line-up often produces inaccurate decisions, with witnesses failing to pick the culprit or picking an innocent suspect. Surprisingly, despite all the scientific advances with respect to the collection of eyewitness evidence, there is absolutely no objective basis for selecting the ‘fillers’ to accompany the suspect in the line-up. Guidelines merely suggest the fillers should not be too similar or too dissimilar to the suspect. However, the fillers are likely to have a crucial influence on decision accuracy. This project aims to remedy this striking deficiency by developing and testing a flexible and universally applicable methodology for photo array composition that will optimise judgmental discriminability and curtail bias.
