The concept of authenticity informs a number of central topics in management studies. On the surface, it might seem that a consensus exists about its meaning; there is indeed widespread agreement that authenticity refers to that which is “real” or “genuine” or “true.” Below the surface, however, there is much less agreement; scholars use the same lexical term but often approach the concept from different perspectives and apply different meanings. This review outlines three fundamental but distinct perspectives found in the literature: authenticity as (1) consistency between an entity’s internal values and its external expressions, (2) conformity of an entity to the norms of its social category, and (3) connection between an entity and a person, place, or time as claimed. The aim of this review was to critically appraise the various research themes within each perspective, highlighting similarities, differences, and relationships between them. In doing so, this review represents an initial step toward an integrated framework of authenticity, which provides new insights into our understanding of the existing literature and a useful guide for future research.
