Social Value Orientation as a Moral Intuition: Decision-Making in the Dictator Game.

We studied the decision making process in the Dictator Game and showed that decisions are the result of a two-step process. In a first step, decision makers generate an automatic, intuitive proposal. Given sufficient motivation and cognitive resources, they adjust this in a second, more deliberated phase. In line with the social intuitionist model, we show that one is Social Value Orientation determines intuitive choice tendencies in the first step, and that this effect is mediated by the dictators perceived interpersonal closeness with the receiver. Self-interested concerns subsequently lead to a reduction of donation size in step 2. Finally, we show that increasing interpersonal closeness can promote pro-social decision-making.
