Abstract: Although there has been a rapid expansion in research on police interrogations and false confessions, little is known about the beliefs of potential jurors as to these issues. In collaboration with a trial research firm, we recruited 461 jury‐eligible men and women who matched the demographic characteristics of jury pools in several states. Surrogate jurors responded to questions and statements in five areas: likely rates of false confessions for different crimes, the ability to discern true from false confessions, beliefs about false confessions, beliefs about permissible interrogation tactics, and beliefs about expert testimony on police interrogations. Results indicated that jurors believed that police interrogators are better than ordinary people at identifying lies and that this ability improves with experience. Jurors believed that they would be able to differentiate a true confession from a false confession by watching a videotape, but were less confident about making such a differentiation from an audio recording. A large majority of the sample reported that it would be helpful to hear expert testimony about interrogation techniques and reasons why a defendant might falsely confess to a crime. There were no significant gender differences. Compared to whites, nonwhite jurors had significantly less confidence in the abilities of the police and gave significantly higher estimates of false confession rates. Results are discussed in light of prior research and implications for jury decision making and expert testimony.
