Abstract
Most previous scholarship on the topic of values in science has focused on individuals. The time is now ripe to study how values permeate science through institutional systems. In order to move this scholarship forward, the present paper develops a taxonomy of major ways in which institutional systems can shape the influences of values on scientific practice. To do so, it examines a case study involving debates about the clinical practice guidelines for preventing and treating Lyme disease. Future research efforts can use this taxonomy as a guide for exploring values in science at an institutional level.
