The use of a wheelchair immediately and profoundly affects how a person is perceived. However, our findings highlight the dynamic nature of perceptions of social identity, which are not only sensitive to personal beliefs, but also highly permeable to intergroup interactions. Having direct contact with people with disabilities might foster positive attitudes in multidisciplinary health care teams. Such interventions could be integrated into medical education programmes to successfully prevent or reduce hidden biases in a new generation of health professionals and to increase the general acceptance of disability in patients.
