Surprise in Science: A qualitative study

Abstract A growing literature in philosophy of science focuses on the role of surprise in scientific practice. The aesthetic dimension of science is also gaining momentum in very recent discussions. While surprising results have been recognised as playing an important epistemic role in science, the literature so far has primarily focused on establishing the power of simulations and thought experiments as compared to experiments and the epistemic superiority of novel predictions over accommodations. In this paper we offer the first empirical analysis of the role of surprise as an aesthetic response, drawing from in-depth interviews with 215 scientists in four countries. We identify what roles scientists assign to surprising results, show that surprise is often experienced as an aesthetic response and identify properties, triggers, and outcomes of surprise in science.
