This article reports two experiments focusing on two stages of the alibi process. In Experiment 1, participants generated a true or false alibi for one of two dates (short or long delay). Results showed that participants were most likely to report that they could get alibi corroboration from a motivated alibi witnesses regardless of whether they were being truthful or deceptive. Changes in details to the generated alibi were frequent for both true and false statements. In Experiment 2, individuals were asked to discriminate between true and false statements. The results indicated that participants were no better than chance at detecting lies. As has been seen with in other domains (e.g. eyewitness identification), confidence had no predictive power in distinguishing lies from true statements.
