Online labor markets have great potential as platforms for conducting experiments, as they provide immediate access to a large and diverse subject pool and allow researchers to conduct randomized controlled trials. We argue that online experiments can be just as valid - both internally and...

It is standard in experimental economics to use decontextualized designs where payoff structures are presented using neutral language. Here we show that cooperation in such a neutrally framed Prisoner’s Dilemma is equivalent to a PD framed as contributing to a cooperative endeavour....

Trust is a central component of social and economic interactions among humans. While rational self-interest dictates that “investors” should not be trusting and “trustees” should not be trustworthy in one-shot anonymous interactions, behavioral experiments with the “trust game” have...

Many previous experiments document that behavior in multi-person settings responds to the name of the game and the labeling of strategies. Usually these studies cannot tell whether frames affect preferences or beliefs. In this Dictator game study, we investigate whether social framing effects...

What is the role of intuitive versus deliberative cognitive processing in human cooperation? The Social Heuristics Hypothesis (SHH) stipulates that (i) intuition favors behaviors that are typically advantageous (i.e. long-run payoff-maximizing), and that for most people cooperation is typically...

Does intuition favor prosociality, or does prosocial behavior require deliberative self-control? The Social Heuristics Hypothesis (SHH) stipulates that intuition favors typically advantageous behavior – but which behavior is typically advantageous depends on both the individual and the...

Are cooperative decisions typically made more quickly or slowly than non-cooperative decisions? While this question has attracted considerable attention in recent years, most research has focused on one-shot interactions. Yet it is repeated interactions that characterize most important...

Does cooperating require the inhibition of selfish urges? Or does “rational” self-interest constrain cooperative impulses? I investigated the role of intuition and deliberation in cooperation by meta-analyzing 67 studies in which cognitive-processing manipulations were applied to economic...
