What is decision science?

Palminteri and Wyart, whose empirical work on decision-making under uncertainty already enriches this library, here tackle the foundational question of what decision science actually is as a discipline. For product direction, this matters because we make decisions about complex systems without a clear epistemological framework — borrowing from psychology, economics, and engineering without understanding how these approaches relate or where they break down. The essay likely maps the intellectual territory between normative rationality (what we should do), descriptive psychology (what we actually do), and prescriptive design (how we can do better). Coming from two researchers who bridge computational modeling and behavioral evidence, this should provide the conceptual clarity that product people need to navigate the decision-making literature intelligently.
