In this study, we examined the impact of the suspect's moral attractiveness (salacious or nonsalacious alibi), the strength of the physical evidence supporting the alibi (strong or weak), and the characteristics of the alibi corroborator (credible or noncredible corroborator) on alibi believability, the likelihood of the suspect being rated guilty, and the ratings of the suspect's character.
We used a 2 (strong or weak alibi) x 2 (salacious or nonsalacious alibi) x 2 (credible or noncredible corroborator) between-subjects design.
They then made several ratings on 11-point Likert scales (e.g., 1 = do not believe the alibi at all to 11 = believe the alibi completely) in relation to alibi believability, suspect guilt, and corroborator believability.
Participants' ratings of alibi believability were assessed via a 2 (strength of alibi evidence) x 2 (salaciousness of alibi) x 2 (credibility of corroborator) between-subjects analysis of variance (ANOVA).
Participants' ratings of the likelihood of guilt were subjected to a 2 (strength of alibi evidence) x 2 (salaciousness of alibi) x 2 (credibility of corroborator) between-subjects ANOVA.
