The adjudication of crime by guilty plea has been on the rise globally for at least the last 30 years. Few countries, however, have accepted pleas to the degree of the United States, whose highest court recently acknowledged a criminal justice system near-synonymous with a “system of pleas, not a system of trials” (Lafler v. Cooper, 2012, p. 3). The present article provides an overview of this justice system wherein many pleas are bargained between the defense and prosecution. Our purpose here is twofold: first to review psychological and other social scientific research on the theoretical and practical reasons underlying the process of pleading guilty, and second, to identify research questions and methods that have yet to be, but need to be, asked and conducted in relation to guilty pleas.

Immediately recalling a witnessed event can increase people's susceptibility to later postevent misinformation. But this retrieval-enhanced suggestibility (RES) effect has been shown only when the initial recall test included specific questions that reappeared on the final test. Moreover, it is unclear whether this phenomenon is affected by the centrality of event details. These limitations make it difficult to generalize RES to criminal investigations, which often begin with free recall prior to more specific queries from legal officials and attorneys. In 3 experiments, we examined the influence of test formats (free recall vs. cued recall) and centrality of event details (central vs. peripheral) on RES. In Experiment 1, both the initial and final tests were cued recall. In Experiment 2, the initial test was free recall and the final test was cued recall. In Experiment 3, both the initial and final tests were free recall. Initial testing increased misinformation reporting on the final test for peripheral details in all experiments, but the effect was significant for central details only after aggregating the data from all 3 experiments. These results show that initial free recall can produce RES, and more broadly, that free recall can potentiate subsequent learning of complex prose materials.
