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.

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.

[Here are two “building blocks.”]

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.

Counter action-oriented biases by recognizing uncertainty

Most executives rightly feel a need to take action. However, the actions we take are often prompted by excessive optimism about the future and especially about our own ability to influence it. Ask yourself how many plans you have reviewed that turned out to be based on overly optimistic forecasts of market potential or underestimated competitive responses. When you or your people feel—especially under pressure—an urge to take action and an attractive plan presents itself, chances are good that some elements of overconfidence have tainted it.

To make matters worse, the culture of many organizations suppresses uncertainty and rewards behavior that ignores it. For instance, in most organizations, an executive who projects great confidence in a plan is more likely to get it approved than one who lays out all the risks and uncertainties surrounding it. Seldom do we see confidence as a warning sign—a hint that overconfidence, overoptimism, and other action-oriented biases may be at work.

Superior decision-making processes counteract action-oriented biases by promoting the recognition of uncertainty. For example, it often helps to make a clear and explicit distinction between decision meetings, where leaders should embrace uncertainty while encouraging dissent, and implementation meetings, where it’s time for executives to move forward together. Also valuable are tools—such as scenario planning, decision trees, and the “premortem” championed by research psychologist Gary Klein (for more on the premortem, see “Strategic decisions: When can you trust your gut?”)—that force consideration of many potential outcomes. And at the time of a major decision, it’s critical to discuss which metrics need to be monitored to highlight necessary course corrections quickly.

The behavioral-strategy journey requires effort and the commitment of senior leadership, but the payoff—better decisions, not to mention more engaged managers—makes it one of the most valuable strategic investments organizations can make.
