On the Distinction Between Personal Standards Perfectionism and Excellencism: A Theory Elaboration and Research Agenda.

Research on perfectionism is flourishing, but the unspecified distinction between perfectionism and the pursuit of excellence is a lingering issue that urgently needs conceptual, theoretical, and empirical attention. In this article, excellence and perfection are defined as distinct goals that form the basis of two different but related constructs. To move this idea forward, the term excellencism is introduced. Perfectionism and excellencism are defined and their similarities and differences are illustrated using symbolic logic and adjectives from the English lexicon. A point is made to clearly indicate that excellencism is a required reference point for reassessing the healthiness or unhealthiness of personal standards perfectionism. Using the law of diminishing returns as an analogy, a theory-driven rationale is proposed, and three alternative hypotheses are formulated. Showing that personal standards perfectionism is associated with better, comparable, and worse outcomes compared with excellencism offers the needed and sufficient conditions for respectively supporting the hypothesis that perfectionism is a healthy, unneeded, or deleterious pursuit. The propositions advanced in this theoretical article are more than incremental, and their practical implications are far-reaching: If personal standards perfectionism yields no added value or deleterious outcomes over and above excellencism, then excellence rather than perfection should be promoted.
