The constraint of decision making research
In the course of their daily responsibilities, executives face a range of decisions, often in each of the four fields outlined here. But decision making research cannot be universally applied. When turning to research to help make better decisions, it’s critical to understand these four fields of decision making. For first- and second-field decisions, cognitive psychologists have demonstrated that people make decisions in ways that do not conform to the tenets of economic rationality. They exhibit systematic biases, which, if surfaced, managers could use to shape routine decisions. For third-field decisions, guidance comes from the branch of economics that studies competitive dynamics: game theory. Game theory can illuminate areas from price competition to geopolitics, yet it has an important limitation: Players cannot alter the terms of the game. So while a great deal of attention has focused on teaching executives to excel at game theory and to be aware of common biases in order to avoid their ill effects, if we apply only those lessons to the world of strategic management, we’re missing a trick. The fourth field of decision making has a layer of complexity that doesn’t lend itself to the careful controls of laboratory experiments, so we know less about how best to make them. What sort of mind-set do they require? When we can influence outcomes, it is useful to summon high levels of self-belief. And when we need to outperform rivals, such elevated levels are not just useful but indeed essential. Only those who are able to muster a degree of commitment and determination that is by some definitions excessive will be in a position to win.
