Snitching, Lies, And Computer Crashes: An Experimental Investigation Of Secondary Confessions, Jessica K. Swanner, Denise Beike, Alexander T. Cole

Two laboratory studies with 332 student participants investigated secondary confessions (provided by an informant instead of the suspect). Participants allegedly caused or witnessed a simulated computer crash, then were asked to give primary or secondary confessions during interrogation. Study 1 replicated the false evidence effect for primary confessions. Secondary confessions were obtained at a high rate, which was increased by false evidence in combination with incentive to confess. In Study 2 a confederate either confessed to or denied crashing the computer. Incentive increased the rate of secondary confession only in the presence of a denial; that is, incentive increased the …

One hundred ninety-two students participated in an experimental simulation testing whether incentives would reduce the reluctance of informants to implicate a close other. Half of the students were made to feel interpersonally close to a confederate who either admitted to or denied a misdeed. All students were interrogated and encouraged to sign a secondary confession stating that the confederate had confessed to the misdeed; half were offered an incentive to do so. Contrary to expectations, closeness did not induce reluctance. Instead, the offer of incentive increased the number of participants willing to sign a secondary confession implicating a close other. …

The present study presents one of the first investigations of the effects of accomplice witnesses and jailhouse informants on jury decision-making. Across two experiments, participants read a trial transcript that included either a secondary confession from an accomplice witness, a jailhouse informant, a member of the community or a no confession control. In half of the experimental trial transcripts, the participants were made aware that the cooperating witness providing the secondary confession was given an incentive to testify. The results of both experiments revealed that information about the cooperating witness’ incentive (e.g., leniency or reward) did not affect participants’ verdict …
