Empirical results often hinge on data analytic decisions that are simultaneously defensible, arbitrary, and motivated. To mitigate this problem we introduce Specification-Curve Analysis, which consists of three steps: (i) identifying the set of theoretically justified, statistically valid, and...

When studies examine true effects, they generate right-skewed p-curves, distributions of statistically significant results with more low (.01s) than high (.04s) p-values. What else can cause a right-skewed p-curve? First, we consider the possibility that researchers report only the smallest...

Journals tend to publish only statistically significant evidence, creating a scientific record that markedly overstates the size of effects. We provide a new tool that corrects for this bias without requiring access to nonsignificant results. It capitalizes on the fact that the distribution of...

Research shows that evidence-based algorithms more accurately predict the future than do human forecasters. Yet, when forecasters are deciding whether to use a human forecaster or a statistical algorithm, they often choose the human forecaster. This phenomenon, which we call algorithm aversion,...

In this paper, we investigate whether making detailed predictions about an event worsens other predictions of the event. Across 19 experiments, 10,896 participants, and 407,045 predictions about 724 professional sports games, we find that people who made detailed predictions about sporting...

Although evidence-based algorithms consistently outperform human forecasters, people often fail to use them after learning that they are imperfect, a phenomenon known as algorithm aversion. In this paper, we present three studies investigating how to reduce algorithm aversion. In incentivized...

Do people have an irrational dislike for risk? People pay less for uncertain prospects than their worst possible outcomes (Gneezy, List, and Wu 2006), and researchers have proposed that this effect occurs because people strongly dislike risk. We challenge this proposition across seven studies....

Four field experiments examined the quantitative and qualitative forces influencing behaviors under consumer elective pricing called “shared social responsibility” (SSR, Gneezy, Gneezy, Nelson, & Brown, 2010). Under SSR consumers can pay what they want and a percentage of their payment goes...
