Studying physicians in training, I investigate how uncertainty and tacit knowledge may give rise to signifi cant practice variation. Consistent with tacit knowledge accruing only with experience, and empirically exploiting a discontinuity in the formation of teams, experience relative to a peer substantially increases the size of variation attributable to the physician trainees. Among the same physician trainees, convergence occurs for patients on services driven by specialists, where there is arguably more explicit knowledge, but not on the general medicine service. This di fference is unexplained by formally coded patient information. In contrast, rich physician characteristics correlated with preferences and ability, and quasi- random assignments to high or low-spending supervising physicians explain little if any variation.
