During 1971-2001, decision-making research crystallized a bounded rationality perspective, showing adaptive heuristics that balance accuracy with cognitive effort under time pressure and processing constraints. Framing and valuation distort choices, with regret and disappointment shaping preferences beyond expected utility. Organizational decision processes emphasize procedural rationality and structured models, while information-search under task complexity reveals systematic search patterns and protocol-analysis-informed forecasts that illuminate decision architectures under uncertainty. Influential Works: Prominent milestones include Choices, Values, and Frames (1984), which established prospect theory's framing and loss aversion as foundational to decision under risk. Later works, such as Regret in Decision Making under Uncertainty (1982) and Disappointment in Decision Making Under Uncertainty (1985), demonstrated how anticipated emotion can steer choice beyond pure utility, whereas Curvature of the Probability Weighting Function (1996) documented nonlinear probability weighting. In the early 2000s, Risk as feelings (2001) integrated affect into risk judgments, signaling a shift toward emotion-informed decision models.
