This is an extremely important point—most research shows that we tend to penalize people for crossing boundaries. We discount generalists and are suspicious of people who engage in activities that seem inconsistent with their identity.

Outsiders aren’t trapped by the paradigms and assumptions that become calcified in industry veterans, nor do they have the existing investments in tools, expertise, or supplier and customer relationships that make change difficult and unappealing.
