The study tested how government communication affects trust during the energy transition. Participants were randomly assigned to receive one of six messages: an environmental, financial or stability message presented by either local or national government, or to a control group. Trust was measured before and after the exercise.

Across the analyses, the messages did not increase trust. The local-government stability message had the most consistent negative effect. By contrast, participation in the exercise itself produced a modest, consistent increase in trust, regardless of which message participants received. Responses differed according to participants’ existing levels of trust, but not according to demographic groups.
