How to induce honesty
Everyday public behavior is premised on honesty. But the imperative to be honest can conflict with self-interest. This conflict between public good and private gain is one of the largest sources of malignity in policymaking, often resulting in noncompliance, inaction, or outright sabotage. This empirical paper examines whether giving the option to be seen as honest helps to reduce malignity in public behavior. We conduct a large field experiment …
Examining the replicability of online experiments selected by a decision market
Here we test the feasibility of using decision markets to select studies for replication and provide evidence about the replicability of online experiments. Social scientists (n = 162) traded on the outcome of close replications of 41 systematically selected MTurk social science experiments published in PNAS 2015-2018, knowing that the 12 studies with the lowest and the 12 with the highest final market prices would be selected for replication, al…
Cash incentives for weight loss work only for males
When governments and healthcare providers offer people cash rewards for weight loss, an assumption is that cash rewards are versatile, working equally well for everyone – for example, for all genders. No research to date has tested for gender difference in response to financial incentives for weight loss. We show in an randomized controlled trial (RCT) ( n = 472) that cash incentives for weight loss only worked for males. The RCT consisted of a 3…
Success at scale
Very often, significantly smaller benefits are observed in final policy outcomes than are indicated by initial research discoveries. Al-Ubaydli et al. have identified a poor understanding of the ‘science of scaling’ as the underlying cause of this discrepancy. They propose a framework to increase our understanding of the science of scaling. We build on this framework by making six specific suggestions capturing three key ideas. First, researchers…

Evaluating replicability of laboratory experiments in economics
Another social science looks at itself Experimental economists have joined the reproducibility discussion by replicating selected published experiments from two top-tier journals in economics. Camerer et al. found that two-thirds of the 18 studies examined yielded replicable estimates of effect size and direction. This proportion is somewhat lower than unaffiliated experts were willing to bet in an associated prediction market, but roughly in lin…
Using the Internet to Administer More Realistic Vignette Experiments
This article illustrates an innovative method of administering stated choice studies (or vignette experiments) using computers and the Internet. The use of video clips to deliver information to research participants makes vignettes more realistic, helps to engage interest of research participants, and can reduce framing effects. The method also provides research participants with interactive options before making judgments. A study to determine t…
Gaming Emotions in Social Interactions
One's own emotions may influence someone else's behavior in a social interaction. If one believes this, she or he has an incentive to game emotions-to strategically modify the expression of a current emotional state-in an attempt to influence her or his counterpart. In a series of three experiments, this article investigates the extent to which people (1) misrepresent a current emotional state, (2) willfully acknowledge their strategic actions, (…
Individual Differences in EWA Learning With Partial Payoff Information
We extend experience-weighted attraction (EWA) learning to games in which only the set of possible \nforegone payoffs from unchosen strategies are known, and estimate parameters separately for each \nplayer to study heterogeneity. We assume players estimate unknown foregone payoffs from a strategy, \nby substituting the last payoff actually received from that strategy, by clairvoyantly guessing the actual \nforegone payoff, or by averaging the se…
A Cognitive Hierarchy Model of Games
Players in a game are “in equilibrium” if they are rational, and accurately predict other players' strategies. In many experiments, however, players are not in equilibrium. An alternative is “cognitive hierarchy” (CH) theory, where each player assumes that his strategy is the most sophisticated. The CH model has inductively defined strategic categories: step 0 players randomize; and step k thinkers best-respond, assuming that other players are di…
Experience-weighted Attraction Learning in Normal Form Games
In ‘experience-weighted attraction’ (EWA) learning, strategies have attractions that reflect initial predispositions, are updated based on payoff experience, and determine choice probabilities according to some rule (e.g., logit). A key feature is a parameter δ that weights the strength of hypothetical reinforcement of strategies that were not chosen according to the payoff they would have yielded, relative to reinforcement of chosen strategies a…
