The value of decision-making power in social decisions

People differ in whether they like to be in control of a decision or whether they would happily delegate a decision. We explore the heterogeneity and the underlying factors of the participants’ values of decision-making power in an allocation choice between a fair and an unfair option. This allocation decision affects the outcomes of the deciding person and three other people in different ways. We find that people differ in their preference for keeping this social decision, and more than 85% never pay for delegating the choice. The value for keeping the decision-making power is affected by the strength, but not the direction of social preferences, and relates to the preference for keeping a useless decision, i.e. selecting the winning number of a lottery. The value of decision-making power is reflected in response times and both eye- and mouse-tracking.
