Validity and Mechanical Turk: An assessment of exclusion methods and interactive experiments

Social science researchers increasingly recruit participants through Amazon's Mechanical Turk (MTurk) platform. Yet, the physical isolation of MTurk participants, and perceived lack of experimental control have led to persistent concerns about the quality of the data that can be obtained from MTurk samples. In this paper we focus on two of the most salient concerns—that MTurk participants may not buy into interactive experiments and that they...
