Certainty of punishment and sentence mitigation in plea behavior

Mitigation of sentence severity has been cited as a primary factor underlying defendant decisions to plead guilty. It has been studied extensively and it has been assumed, but rarely examined, that few defendants plead guilty in the absence of significant benefits. This paper examines the relationship between sentence benefits and plea behavior. A crime-specific analysis reveals that some defendants frequently plead guilty in the relative absence of significant benefits; conversely, others plead not guilty even though significant benefits are available for guilty pleaders. Applying several decision theory constructs to justice system processing, the defendant's desire to reduce uncertainty is discussed and offered as a tentative explanation for the phenomenon of pleading guilty in the relative absence of significant benefits.
