Self-selection or indoctrination in the study of (standard) economics: A systematic literature review

Considerable academic debate exists as to whether students with a background in economics exhibit distinct behavioural patterns that set them apart from students in other academic disciplines. Primarily, the debate concerns whether students who fit the stereotype of the economist choose to study economics (the self-selection hypothesis) or whether economics students develop these behavioural patterns in the course of their university studies (the indoctrination hypothesis). We conducted a systematic literature review that examines both hypotheses. According to the literature reviewed, the majority of researchers find the self-selection hypothesis to be the best supported. However, findings remain inconclusive due to several methodological limitations. In spite of that, this study should facilitate a deeper understanding of what causes behavioural changes in economics students and what exactly these behavioural differences are, among other relevant hypotheses.
