✦ Synopsis
Various measures have been proposed to test the fairness of lineups (Doob & Kirshenbaum, 1973;Malpass, 1981;Wells, Leippe and Ostrom, 1979). In three experiments, we examined the relationship of identi®cation accuracy to measures of lineup bias ( proportion of mock witness choices, defendant bias, functional size) and lineup size (eective size, number of acceptable lineup members). Lineup bias measures successfully postdict false positive choices, but only for some lineup procedures. Lineup size measures rarely postdict false positive decisions. Lineup fairness measures do not postdict false identi®cations from sequential lineups. Implications for measuring and reporting lineup fairness in court are discussed.
