A widely used measure of individual propensity to utilize analytic processing is the Cognitive Reflection Test (CRT), a set of math problems with intuitively compelling but incorrect answers. Here, we ask whether scores on this measure are temporally stable. We aggregate data from 11 studies run...

Microcredit—the distribution of small, uncollateralized but jointly liable loans to the poorest of the poor—has been touted as a powerful approach for combatting global poverty. While some microcredit programs enjoy high repayment rates, others face unsustainably high default rates. Efforts...

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...

Online experiments allow researchers to collect datasets at times not typical of laboratory studies. We recruit 2,336 participants from Amazon Mechanical Turk to examine if participant characteristics and behaviors differ depending on whether the experiment is conducted during the day versus...

Two separate bodies of work have examined whether culture affects cooperation in economic games and whether cooperative or non-cooperative decisions occur more quickly. Here, we connect this work by exploring the relationship between decision time and cooperation in American versus Indian...

Why do individuals pay costs to punish selfish behavior, even as third-party observers? A large body of research suggests that reputation plays an important role in motivating such third-party punishment (TPP). Here we focus on a recently proposed reputation-based account (Jordan et al., 2016)...

We examine the possibility that self-interest, typically thought to undermine social welfare, might actually be harnessed to reduce in-group bias. We compare behavior in a Dictator Game (DG), where participants unilaterally divide money between themselves and a recipient, and an Ultimatum Game...

We let participants indicate their intended action in a repeated game experiment where actions are implemented with errors. Even though communication is cheap talk, we find that the majority of messages were honest (although the majority of participants lied at least occasionally). As a result,...

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...

Agent-based modeling is a longstanding but under-used method that allows researchers to simulate artificial worlds for hypothesis testing and theory building. Agent-based models (ABMs) offer unprecedented control and statistical power by allowing researchers to precisely specify the behavior of...
