Abstract: Social learning has been shown to be more prevalent within organizations rather than across. To explain this regularity, prior research points mostly to structural conditions prevalent inside organizations, such as proximity or organization-specific language. We complement these explanations with an individual-based view: people display a behavioral disposition for high-fidelity social learning (i.e., copying with high accuracy from others) when learning from members of their own organization (and not from outside sources). First, we use a simple formal model from cultural evolution to justify why this behavioral disposition would have evolved to become a part of our norms and/or psychology. Then, we use a pre-registered field experiment to provide empirical support for this individual-level disposition. In our experiment, we document a significant increase in social learning when doing so from fellow organizational members, of which 75% can be attributed to high-fidelity social learning. This effect trumps prestige-biased social learning and, consistent with a predisposition, it seems to operate through sentiments and not reason. (Authors: Poblete, J., Brahm, F., Macera, R.)
