Abstract
Presenting a blank lineup—containing only fillers—to witnesses prior to showing a real
lineup might be useful for screening out those who pick from the blank lineup as unreliable
witnesses. We show that the effectiveness of this procedure varies depending on instructions
given to witnesses. Participants (N = 462) viewed a simulated crime and attempted to identify
the perpetrator from a lineup approximately one week later. Rejecting a blank lineup was
associated with greater identification accuracy and greater diagnosticity of suspect
identifications, but only when witnesses were instructed prior to the blank lineup that they
would view a series of lineups; the procedure was ineffective for screening when witnesses
were advised they would view two lineups or received no instruction. These results highlight
the importance of instructions used in the blank lineup procedure, and the need for better
understanding of how to interpret choosing patterns in this paradigm.
