An Immovable Object? In-Group Qualifiers, Credibility, and Expert Claims on Punitive Sex Crime Policy

Punitive policy approaches toward individuals convicted of sexual offenses (ICSOs) remain popular despite limited evidence of their effectiveness. Science communicators face substantial challenges in shifting public opinion on these issues, and prior research suggests that advocating for less punitive but more effective policies can undermine perceived expert credibility. This study reports results from a survey experiment with U.S. adults examining whether experts’ use of empathetic in-group qualifiers mitigates credibility losses and increases belief in their claims. Bayesian structural equation models indicate no systematic effects of qualifier use on credibility or belief, underscoring persistent barriers to communicating about stigmatized justice populations.
