Although researchers often assume their participants are naive to experimental materials, this is not always the case. We investigated how prior exposure to a task affects subsequent experimental results. Participants in this study completed the same set of 12 experimental tasks at two points in time, first as a part of the Many Labs replication pr...

Crowdsourcing services-particularly Amazon Mechanical Turk-have made it easy for behavioral scientists to recruit research participants. However, researchers have overlooked crucial differences between crowdsourcing and traditional recruitment methods that provide unique opportunities and challenges. We show that crowdsourced workers are likely to...

Although participants with psychiatric symptoms, specific risk factors, or rare demographic characteristics can be difficult to identify and recruit for participation in research, participants with these characteristics are crucial for research in the social, behavioral, and clinical sciences. Online research in general and crowdsourcing software i...

In a series of experimental studies, we asked people to assign appropriate civil and/or criminal liability to individuals who cause harm with various culpable states of mind and kinds of knowledge. The studies are principally aimed at two related issues. First, do people actually separate the various states of mind conceptually? How much knowledge,...

Criminal liability has classically been dependent on intentionally causing harm. However, the reach of federal criminal law has recently expanded to include many strict liability crimes and crimes with less than intentional mens rea requirements. In a series of studies, we investigate laypeople’s intuitions about the appropriateness of criminal and...

Duplicate respondents across related experiments are a substantial problem for conducting programmatic research on AMT. In this tutorial, we provide a straightforward alternative that allows researchers who use Qualtrics to exclude workers who participated in a previous study. This approach allows researchers to exclude workers who have completed a...

While the Mechanical Turk web interface allows researchers to contact research participants individually, it is frequently necessary to email participants en masse. In this working paper we describe how to email up to 100 workers at a time using boto.

Despite persistent calls for more empirical legal scholarship, only recently have scholars provided evidence that empirical legal scholarship has indeed entered the mainstream of the legal academy. Defining empirical scholarship as the systematic organization of a series of observations with the method of data collection and analysis made available...
