Supply of willful ignorance

Spoiling the Party: Experimental Evidence on the Willingness to Transmit Inconvenient Ethical Information

With Ivan Soraperra and Joël van der Weele.

Abstract: Many people would rather not tell their friends that their decisions can negatively affect a third party, for example by explaining the environmental harm of meat consumption. This paper examines under which circumstances people are willing to interfere by sharing or hiding information: in other words, the supply of willful ignorance. We use a simple online experiment to explore three possible concerns in this situation: own payoffs, charity payoffs and concerns about the decision maker. We developed a new two-person sender-receiver game in which the Receiver decides between a default option with zero payoffs for self and charity, versus a button click which yields a positive payoff to self, but uncertain payoffs for charity. Senders can send a message with the true value of charity payoff, or suppress such inconvenient information to ‘help’ decision makers staying ignorant. We measure the impact of the three concerns and their relationships with different treatments in a large (N = 1512) pre-registered online experiment, controlling for charity preference and the size of the externality.
