Open Sampling in Behavioral Research

A huge proportion of participants in behavioral science studies are recruited from “open sampling” services, such as MTurk and Prolific. These services can accelerate and democratize the production of scientific knowledge. They also allow researchers to collect larger samples compared to traditional samples in behavioral research (e.g., undergraduate students). However, open sampling also poses unique challenges to behavioral researchers. For example, data quality seems to fluctuate across time, and participants' research experience might occasionally threaten experimental validity and replicability. Researchers also face a tradeoff between collecting larger samples and providing ethical payments to individuals who participate in research to earn a living wage. I will present the evidence underlying some of the issues underlying open sampling, and discuss recommendations for researchers to improve their survey and experimental practices.
