The Centre for Experimental Social Science (CESS) is dedicated to all areas of experimental social science research. With centres located in Oxford (UK), Santiago (Chile) and Pune (India), CESS has an international reputation for the promotion and facilitation of laboratory, online and in the field experiments across all areas of the social sciences. CESS contains researchers from political science, sociology, social psychology, and economics. Our research is based on a highly interdisciplinary mix of methods, including laboratory, lab-in-the-field, online, and field experiments. Current research by members of CESS covers topics across the social sciences, including cheating and tax compliance across cultures, the dynamics underlying socially harmful traditions like female genital cutting, or the link between religion and social insurance in small-scale societies, as well as general research on experimental methodology. Nuffield College has a strong commitment to promoting cross-disciplinary research in the social sciences, and CESS is a major contribution to this mandate. CESS provides infrastructure for laboratory, lab-in-the-field, online and field experiments. These centres give researchers the unique opportunity to conduct experiments with subject pools from three distinct regions: Latin America, Asia, and Europe. Moreover, all subject pools contain student subjects as well as non-student subjects from their respective local populations. CESS also supports a variety of fellowships, postdoctoral programs, seminars, summer schools, workshops, and conferences.CESS was founded at Nuffield College, University of Oxford, in 2008 and the Oxford lab remains the centre’s official hub. It is an important facility for researchers and students at the University of Oxford, as well as for experimentalists from around the world.
