The research examined how adults’ beliefs about gender development relate to their views of transgender youth. In the first study, 200 adults tended to believe that transgender youth develop gender identity later than cisgender youth. That belief predicted less support for children’s autonomy in determining their gender identity and greater support for laws that limit transgender rights.

In two further studies, participants learned about similarities in the development of transgender and cisgender children. This intervention reduced the belief that transgender youth develop gender identity later. The change was linked to greater support for children’s autonomy in a nationally representative sample of 1,552 people and to increased donations to an organization supporting transgender youth in a study of 174 people.
