The case for behavioral strategy PART I

Left unchecked, subconscious biases will undermine strategic decision making. Here’s how to counter them and improve corporate performance.

Once heretical, behavioral economics is now mainstream. Money managers employ its insights about the limits of rationality in understanding investor behavior and exploiting stock-pricing anomalies. Policy makers use behavioral principles to boost participation in retirement-savings plans. Marketers now understand why some promotions entice consumers and others don’t.

Yet very few corporate strategists making important decisions consciously take into account the cognitive biases—systematic tendencies to deviate from rational calculations—revealed by behavioral economics. It’s easy to see why: unlike in fields such as finance and marketing, where executives can use psychology to make the most of the biases residing in others, in strategic decision making leaders need to recognize their own biases. So despite growing awareness of behavioral economics and numerous efforts by management writers, including ourselves, to make the case for its application, most executives have a justifiably difficult time knowing how to harness its power.

This is not to say that executives think their strategic decisions are perfect. In a recent McKinsey Quarterly survey of 2,207 executives, only 28 percent said that the quality of strategic decisions in their companies was generally good, 60 percent thought that bad decisions were about as frequent as good ones, and the remaining 12 percent thought good decisions were altogether infrequent. Our candid conversations with senior executives behind closed doors reveal a similar unease with the quality of decision making and confirm the significant body of research indicating that cognitive biases affect the most important strategic decisions made by the smartest managers in the best companies. Mergers routinely fail to deliver the expected synergies.³Strategic plans often ignore competitive responses. And large investment projects are over budget and over time—over and over again.⁵

In this article, we share the results of new research quantifying the financial benefits of processes that “debias” strategic decisions. The size of this prize makes a strong case for practicing behavioral strategy—a style of strategic decision making that incorporates the lessons of psychology. It starts with the recognition that even if we try, like Baron Münchhausen, to escape the swamp of biases by pulling ourselves up by our own hair, we are unlikely to succeed. Instead, we need new norms for activities such as managing meetings (for more on running unbiased meetings, see “Taking the bias out of meetings”), gathering data, discussing analogies, and stimulating debate that together can diminish the impact of cognitive biases on critical decisions. To support those new norms, we also need a simple language for recognizing and discussing biases, one that is grounded in the reality of corporate life, as opposed to the sometimes-arcane language of academia. All this represents a significant commitment and, in some organizations, a profound cultural change.

The value of good decision processes

Think of a large business decision your company made recently: a major acquisition, a large capital expenditure, a key technological choice, or a new-product launch. Three things went into it. The decision almost certainly involved some fact gathering and analysis. It relied on the insights and judgment of a number of executives (a number sometimes as small as one). And it was reached after a process—sometimes very formal, sometimes completely informal—turned the data and judgment into a decision.

Our research indicates that, contrary to what one might assume, good analysis in the hands of managers who have good judgment won’t naturally yield good decisions. The third ingredient—the process—is also crucial. We discovered this by asking managers to report on both the nature of an important decision and the process through which it was reached. In all, we studied 1,048 major decisions made over the past five years, including investments in new products, M&A decisions, and large capital expenditures.

The research analyzed a variety of decisions.

We asked managers to report on the extent to which they had applied 17 practices in making that decision. Eight of these practices had to do with the quantity and detail of the analysis: did you, for example, build a detailed financial model or run sensitivity analyses? The others described the decision-making process: for instance, did you explicitly explore and discuss major uncertainties or discuss viewpoints that contradicted the senior leader’s? We chose these process characteristics because in academic research and in our experience, they have proved effective at overcoming biases.

After controlling for factors like industry, geography, and company size, we used regression analysis to calculate how much of the variance in decision outcomes⁷ was explained by the quality of the process and how much by the quantity and detail of the analysis. The answer: process mattered more than analysis—by a factor of six. This finding does not mean that analysis is unimportant, as a closer look at the data reveals: almost no decisions in our sample made through a very strong process were backed by very poor analysis. Why? Because one of the things an unbiased decision-making process will do is ferret out poor analysis. The reverse is not true; superb analysis is useless unless the decision process gives it a fair hearing.

To get a sense of the value at stake, we also assessed the return on investment (ROI) of decisions characterized by a superior process. The analysis revealed that raising a company’s game from the bottom to the top quartile on the decision-making process improved its ROI by 6.9 percentage points. The ROI advantage for top-quartile versus bottom-quartile analytics was 5.3 percentage points, further underscoring the tight relationship between process and analysis. Good process, in short, isn’t just good hygiene; it’s good business.

The building blocks of behavioral strategy

Any seasoned executive will of course recognize some biases and take them into account. That is what we do when we apply a discount factor to a plan from a direct report (correcting for that person’s overoptimism). That is also what we do when we fear that one person’s recommendation may be colored by self-interest and ask a neutral third party for an independent opinion.

However, academic research and empirical observation suggest that these corrections are too inexact and limited to be helpful. The prevalence of biases in corporate decisions is partly a function of habit, training, executive selection, and corporate culture. But most fundamentally, biases are pervasive because they are a product of human nature—hardwired and highly resistant to feedback, however brutal. For example, drivers laid up in hospitals for traffic accidents they themselves caused overestimate their driving abilities just as much as the rest of us do.⁹

Improving strategic decision making therefore requires not only trying to limit our own (and others’) biases but also orchestrating a decision-making process that will confront different biases and limit their impact. To use a judicial analogy, we cannot trust the judges or the jurors to be infallible; they are, after all, human. But as citizens, we can expect verdicts to be rendered by juries and trials to follow the rules of due process. It is through teamwork, and the process that organizes it, that we seek a high-quality outcome.

Building such a process for strategic decision making requires an understanding of the biases the process needs to address. In the discussion that follows, we focus on the subset of biases we have found to be most relevant for executives and classify those biases into five simple, business-oriented groupings. (You can download a PDF of the groupings of biases that occur most frequently in business.) A familiarity with this classification is useful in itself because, as the psychologist and Nobel laureate in economics Daniel Kahneman has pointed out, the odds of defeating biases in a group setting rise when discussion of them is widespread. But familiarity alone isn’t enough to ensure unbiased decision making, so as we discuss each family of bias, we also provide some general principles and specific examples of practices that can help counteract it.

Counter pattern-recognition biases by changing the angle of vision

The ability to identify patterns helps set humans apart but also carries with it a risk of misinterpreting conceptual relationships. Common pattern-recognition biases include saliency biases (which lead us to overweight recent or highly memorable events) and the confirmation bias (the tendency, once a hypothesis has been formed, to ignore evidence that would disprove it). Particularly imperiled are senior executives, whose deep experience boosts the odds that they will rely on analogies, from their own experience, that may turn out to be misleading.Whenever analogies, comparisons, or salient examples are used to justify a decision, and whenever convincing champions use their powers of persuasion to tell a compelling story, pattern-recognition biases may be at work.

Pattern recognition is second nature to all of us—and often quite valuable—so fighting biases associated with it is challenging. The best we can do is to change the angle of vision by encouraging participants to see facts in a different light and to test alternative hypotheses to explain those facts. This practice starts with things as simple as field and customer visits. It continues with meeting-management techniques such as reframing or role reversal, which encourage participants to formulate alternative explanations for the evidence with which they are presented. It can also leverage tools, such as competitive war games, that promote out-of-the-box thinking.

Sometimes, simply coaxing managers to articulate the experiences influencing them is valuable. According to Kleiner Perkins partner Randy Komisar, for example, a contentious discussion over manufacturing strategy at the start-up WebTV suddenly became much more manageable once it was clear that the preferences of executives about which strategy to pursue stemmed from their previous career experience. When that realization came, he told us, there was immediately a “sense of exhaling in the room.” Managers with software experience were frightened about building hardware; managers with hardware experience were afraid of ceding control to contract manufacturers.

Getting these experiences into the open helped WebTV’s management team become aware of the pattern recognition they triggered and see more clearly the pros and cons of both options. Ultimately, WebTV’s executives decided both to outsource hardware production to large electronics makers and, heeding the worries of executives with hardware experience, to establish a manufacturing line in Mexico as a backup, in case the contractors did not deliver in time for the Christmas season. That in fact happened, and the backup plan, which would not have existed without a decision process that changed the angle of vision, “saved the company.”

Another useful means of changing the angle of vision is to make it wider by creating a reasonably large—in our experience at least six—set of similar endeavors for comparative analysis. For example, in an effort to improve US military effectiveness in Iraq in 2004, Colonel Kalev Sepp—by himself, in 36 hours—developed a reference class of 53 similar counterinsurgency conflicts, complete with strategies and outcomes. This effort informed subsequent policy changes.
