The moment you decide, you divide: How politicians assess procedural fairness

Are politicians more rational decision makers than citizens? This article contributes to the ongoing debate by examining how politicians and citizens assess the fairness of the process leading to a controversial policy decision. It contains theories as to why it is tempting to match the favourability of policy decision with a fairness assessment of the preceding process, and how politicians and citizens differ in their approach to the task. Having derived three hypotheses, parallel scenario experiments are run in large samples of Swedish politicians and citizens, in which the outcome and fairness of a policy decision process are manipulated. As predicted, it is found that both politicians and citizens match the favourability of the decision with the assessment of the process, that these self‐serving biases are stronger among politicians, and that policy engagement accounts for the group‐level difference.
