Consolidation and Exploration: An Article-Level Distinction for the Practice of Science

This paper proposes a distinction, at the level of the individual article, between consolidation and exploration as modes of scientific work. The distinction complements existing frameworks at the level of historical epochs (Kuhn's paradigms) and research programmes (Lakatos): together they form a temporally layered picture, in which the present proposal supplies the short-scale, prospective criterion that scientists can apply to their ongoing work. We offer four operational questions that help classify a given project or manuscript as predominantly consolidating or exploratory, and argue that exploration cannot be fairly evaluated by the same metrics used for consolidation. We introduce fertility---backwards, in terms of anomaly resolution, and forwards, in terms of new questionsopened---as a primary criterion for exploratory work, and distinguish its latent face, assessable at publication, from its realised face, visible only in hindsight; we further separate foundational exploration, which introduces new primitives, from work that recombines existing ones. Two paradigmatic cases, Planck's 1900 paper on black-body radiation and Einstein's 1915 work on general relativity, illustrate how the same activity can be misjudged if assessed with the wrong mode in mind. We conclude that many distortions of present-day science stem less from ideological hostility to novelty than from a structural mismatch: exploration is routinely judged by consolidating yardsticks.
