Pressing questions in the study of psychological and behavioral diversity

Abstract

Extreme biased sampling of research participants and the neglect of their cultural context are increasingly recognized as threats to the generalizability of much of what we know about human thought and behavior (1, 2). In addition to reinforcing narrow views of what it means to be human, these parochial research practices have also shaped the methodological core of the human sciences by favoring tasks that are tailored to the skills, motivations, and social expectations of a very rarefied set of humanity (3). Despite decades of calls for reform, there is little evidence that increasing awareness of this threat has led to changes in practice or publishing (2, 4). This special issue stems from the Sackler Colloquium on “Pressing Questions in the Study of Psychological and Behavioral Diversity” (September 7–9, 2017) designed to address these issues. Building on discussions emerging from two National Science Foundation-funded workshops held in 2016 and 2017, the colloquium convened scholars from a wide range of disciplines who have conducted important research with diverse populations. The colloquium participants identified barriers that discourage researchers from harnessing the full breadth of human diversity for understanding human thought and behavior. These included concerns about current peer review practices, methodological narrowness, lack of researcher diversity, and the need for theoretical frameworks that are sensitive to cultural, social, and ecological variation. Participants also shared innovations and insights from their own research that can foster and inform future investigations of human diversity. In this introduction, we highlight three threads that weave together the 10 papers in this special issue. The first thread documents the theoretical and practical payoffs of engaging with a broader range of participants (and the pitfalls of failing to do so). The second thread identifies barriers to pursuing such work and proposes potential solutions to overcome them. … [↵][1]1To whom correspondence should be addressed. Email: dhruschk{at}asu.edu.
