Abstract

Epistemic uncertainty is a huge area of scholarship. It has captured the minds of scholars in psychology and many domain-specific studies of reasoning and problem solving. What does it mean to resolve uncertainty? This chapter explores the idea that resolution of uncertainty in complex science and engineering fields frequently ends with approximations rather than precise answers. The chapter begins by examining language to motivate the core distinction between uncertainty and approximation. Then, the chapter explores whether the distinction can be defended empirically in reliable and valid coding of speech and gesture data in multiple science and engineering domains. Novice/Expert changes in uncertainty and approximation levels are also explored. Finally, three examinations of temporal patterns of co-occurrence with uncertainty and approximation are presented in multiple problem-solving domains to provide an overall model of uncertainty being transformed to approximation through spatial reasoning and mental simulations. © 2010, Elsevier Inc.
