Abstract

There is insufficient data on the effect of lineup size on identifications in large lineups. This study therefore compared 48-person lineups, a size used often in large lineup experiments, with a lineup double the size, 96. At least one hour after viewing a two-minute video featuring the target, other people and other objects, 52 participants viewed 48-person lineups (four screens of 12) or a 96-person lineup (eight screens of 12). No difference was found in the rate of identifications between the two lineup sizes. The conclusion is that the larger lineup is superior due to the smaller chance of mistakenly choosing an innocent suspect.
