Using stereotype violation to shift causal understanding and attitudes about weight.

Objective: We evaluated an approach to weight stigma reduction involving the provision of an exemplar inconsistent with belief systems underlying weight bias. Specifically, that people with higher weight eat unhealthy, high-calorie diets, and people with lower weight eat healthy, low-calorie diets. Providing exemplars that violate the stereotype's assumptions may lead to a change in beliefs, stereotypes, and ultimately, stigma.
