New Article on Wrongful Convictions and Public Opinion

A new article by Robert Norris and Kevin Mullinix explores how wrongful convictions affect public opinion has been published online in the Journal of Experimental Criminology.

The paper examines the effects of both statistical or numerical information (i.e., numbers of wrongful convictions) and narratives (i.e., a story about a wrongful conviction) on public attitudes toward the justice system, including support for the death penalty, support for police reforms, trust in the justice system, and personal concern about wrongful convictions.

Discourse about criminal justice in the USA increasingly revolves around wrongful convictions. Research has documented the emergence of the “innocence frame,” but relatively little is known about its effects on public opinion. We utilize framing theory to examine how various presentations of wrongful conviction information affect attitudes toward the justice system and highlight the consequences of the innocence movement for public opinion.


We implement two survey experiments to test the effects of innocence information for criminal justice attitudes. In the first experiment, we test the impact of wrongful conviction numbers relative to a control group for death penalty support. In the second experiment, we analyze the effects—both separately and jointly—of exoneration numbers and a wrongful conviction narrative relative to a control group for attitudes toward the death penalty and police reform, trust in the justice system, and personal concern.


We demonstrate that the presentation of factual numbers of exonerations reduces support for capital punishment and erodes trust in the justice system, but fails to garner support for police reforms or increase personal concern about wrongful convictions. However, a narrative about an individual wrongful conviction predictably has more pronounced effects on death penalty attitudes and increases personal concern and support for police reform, but has little effect on trust in the justice system more broadly.


Wrongful convictions are consequential for public opinion, but the effects are contingent on how the information is framed and the attitudinal outcome of interest. Our findings have implications for criminal justice attitudes and policy, the innocence movement, and framing theory.


New article on How Innocents Enter the System

A new article from Belen Lowrey-Kinberg and colleagues was recently published in Crime & Delinquency. The article explores how innocents become suspects and enter the criminal justice system. The full citation and abstract are below. More information can be found here.

Drawing from the investigative policing literature, we develop a typology for how innocent defendants become suspects in criminal investigations. We use the Preventing Wrongful Convictions Project (PWCP) dataset and multivariate modeling to examine the case and defendant characteristics that predict how an innocent defendant became a suspect. We found that investigators identify suspects in eight primary ways. The most common in the PWCP dataset were victim/eyewitness identification, citizen identification, and intentional misidentification. Defendant’s race, age, criminal history, relationship to the victim, cognitive/mental status, and whether the victim survived were strongly associated with an innocent defendant’s origin of implication. These results illuminate how tunnel vision begins in cases with innocent defendants, and how police practices may prevent innocent individuals from becoming suspects.
