Neuroeconomics tries to bridge the disciplines of neuroscience, psychology, and economics. I think of economics and psychology as really, in some sense, one discipline. I know that that’s a strident statement to make, but they really are siblings separated at birth. Psychology and economics are complementary disciplines, in many cases studying the same phenomena: decision making, value-based judgment, heuristics. One side approaches it from a phenomenological, experiment-driven perspective and the other from an abstract, theoretical perspective.
