Key Takeaway
Note: Mental contrasting interventions showed no consistent benefit for reducing intergroup anxiety or prejudice.

Two preregistered randomized controlled trials tested mental contrasting interventions for reducing intergroup anxiety and prejudice toward Black people among White US adults. Study 1 (N=300) compared imagining a negative-then-positive interaction with imagining positive-only interactions with either Black or White individuals. Study 2 (N=149) compared imagining a neutral-then-positive interaction with imagining positive-only interactions with Black individuals. Both studies were conducted online with immediate outcome measurement.

In Study 1, the intervention condition showed higher intergroup anxiety compared to controls, with a significant condition × time interaction. However, this effect did not replicate in Study 2. Across both studies, the intervention did not significantly reduce prejudice or increase contact intentions toward Black individuals. No effect sizes, absolute numbers, or p-values were reported for these outcomes.

No adverse events, serious adverse events, discontinuations, or tolerability data were reported. The authors note that their preregistered tests did not support their hypothesis, and the failure to replicate effects across studies constrains claims regarding robustness and generalizability. The practice relevance of these findings was not reported, and the evidence does not support using this specific mental contrasting approach for reducing intergroup anxiety or prejudice in clinical settings.

What if you could practice a difficult conversation in your head to feel less anxious about it in real life? Researchers tested this idea to see if White adults could reduce their anxiety and prejudice toward Black people by first imagining a negative or neutral interaction, followed by a positive one. They ran two online studies with hundreds of participants, comparing this mental exercise to just imagining positive interactions.

The results were not what the researchers hoped. In the first study, people who did the 'negative-then-positive' imagining actually reported higher anxiety afterward. But when they ran a second, similar study, that increase in anxiety didn't happen again. Across both studies, the mental exercise did not significantly reduce prejudice or make people more willing to have contact with Black individuals.

This was a preregistered study, meaning the researchers publicly stated their plan and predictions beforehand, which adds weight to the finding that their main hypothesis wasn't supported. The fact that the anxiety result from the first study didn't show up in the second one means we can't be confident the effect is real or reliable. For now, this specific mental exercise doesn't appear to be a simple solution for reducing intergroup anxiety or prejudice.

What this means for you:
Imagining a tough conversation didn't reliably reduce racial anxiety or prejudice in this study.

Intergroup anxiety can undermine positive intergroup relations. This Registered Report presents two preregistered online studies testing a mental contrasting intervention to reduce intergroup anxiety towards Black individuals. Previous work aimed to inoculate anxiety by having participants imagine a threatening intergroup experience followed by a positive one, compared to only imagining positive interactions. In Study 1 (N = 300), White US adults were randomly assigned in a 2 × 2 design to imagine either a negative-then-positive interaction (intervention) or positive-only interactions with an outgroup (Black) or ingroup (White) member. State anxiety was measured immediately before and after the second imagined interaction, followed by prejudice and contact intentions. Study 2 (N = 149) replicated the outgroup conditions and tested whether imagining a neutral-then-positive interaction reduced anxiety relative to imagining positive-only interactions. Contrary to preregistered predictions, Study 1 showed higher intergroup anxiety in the intervention condition and a significant condition × time interaction. These effects did not replicate in Study 2. Across both studies, the intervention did not significantly reduce prejudice or increase contact intentions. Overall, the preregistered tests did not support the hypothesis that this intervention reduces intergroup anxiety or related outcomes, constraining claims regarding its robustness and generalizability.
