On Identifying Human Capital: Flawed Knowledge Leads to Faulty Judgments of Expertise by Individuals and Groups

Abstract

Abstract Purpose To thrive, any individual, organization, or society needs to separate true from false expertise. This chapter provides a selective review of research examining self and social judgments of human capital – that is, expertise, knowledge, and skill. In particular, it focuses on the problem of the “flawed evaluator”: most people judging expertise often have flawed expertise themselves, and thus their assessments of self and others are imperfect in profound and systematic ways. Methodology/approach The review focuses mostly on empirical work specifically building on the “Dunning–Kruger effect” in self-perceptions of expertise (Kruger & Dunning, 1999). This selective review, thus, focuses on patterns of error in such judgments. Findings Because judges of expertise have flawed expertise themselves, they fail to recognize incompetence in themselves. Because of their flaws, most people also fail to recognize genius in other people and superior ideas. Practical implications The review suggests that organizations have trouble recognizing those exhibiting the highest levels of expertise in their midst. People in organizations also fail to identify the best advice and correct flawed ideas. Organizations may also rely on the “wisdom of crowds” strategy in situations in which that strategy actually misleads because too few people identify the best idea available.
