Participants described how working with collaborators with roots in other disciplines or fields introduced challenges stemming from discipline-based differences in values, terminology, and work styles. These included strongly held, yet often implicit, beliefs around what constituted interesting and valuable research questions, variables, and methods. A number of interview participants said that these differences were reflected in an implicit devaluation of other disciplines. There seems to be this attitude present in nearly every discipline that what they do is better than what the guys do across the hall. And they've been practicing for years and years how to criticize other people's work, without actually knowing what they do.
