Intent-to-Treat in the cheating paradigm: a meta-analysis

ObjectivesThe cheating paradigm is an often-used procedure that randomly assigns participants to cheat (guilty) or not cheat (innocent). However, not all participants conform to their assigned condition. We investigated the potential impact of including non-conformers in analyses under an intent-to-treat model (ITT) on decisions to confess, plea, and waive Miranda rights.MethodsWe conducted a series of meta-analyses with studies that used the cheating paradigm to study the legal decisions of mock suspects and that provided enough statistical information for all participants.ResultsOverall, non-conforming guilty participants had lower odds of confessing, pleading guilty, and waiving Miranda rights than conforming guilty participants, whereas non-conforming innocent participants had higher odds. Importantly, including non-conforming participants under an ITT model attenuates, but does not eliminate, the effect of guilt status on decisions. ConclusionsThese findings highlight how willingness to cheat influences legal outcomes and that researchers need to more carefully consider non-conforming participants.

Automated summary

This study demonstrates that participants' willingness to conform to assigned conditions affects their legal decisions, with non-conforming participants being less likely to confess, plead guilty, and waive Miranda rights. The researchers emphasize the importance of considering non-conforming participants in analyses and interpretations.
