Synonym(s)
- dud effect
Scope note
- For example, Charman, Wells & Joy (2011) asked participants in their experiments to view a crime scene. Then, they were asked to identify the culprit in a police lineup. In fact, the culprit was not presented in the lineup. The results showed that the presence of implausible persons in the lineup (because their physical appearance was visually very different from that of the perpetrator) increased participants' confidence in identifying the perpetrator when they chose a plausible person (i.e. one who looked like the perpetrator).
