How noisy is your company?

Companies live and die by the ability of the people who work within them to make sound judgments. Their judgments determine what strategy to follow, where to invest R&D funds, how to set prices, who to hire and promote, and a myriad of other decisions. Some of the decisions are one-offs; others are made repeatedly. There’s just one problem, assert Daniel Kahneman, Olivier Sibony, and Cass Sunstein: “Wherever there is judgment, there is noise — and more of it than we think.”

Noise is the major source of variability in judgment and, thus, a major cause of decisions that miss their mark, according to the professorial supergroup (henceforth, KSS). Kahneman was awarded a Nobel Prize for his work as a behavioral economist; Sibony is an expert on decision-making who teaches at HEC Paris and Oxford’s Saïd Business School; and Sunstein is the Harvard prof whose work on nudges has been influential in public policy.

Noise is also the title of the trio’s new book, a 400-page tome that should leave executives who take the time to wade through it more than a little unsettled. Their uneasiness should stem from the likelihood that they have been underestimating the negative effects of noise on decision-making in their organizations. When KSS asked 828 senior executives in a variety of industries how much variation they expected to find in expert judgments, their median answer was 10 percent.

In reality, the variation in expert judgments can be four to five times that. When two members of KSS ran a noise audit for an insurance company, they discovered that the median difference in the pricing determined by its underwriters for identical policies was 55 percent, and the median difference in the payouts determined by its claims adjusters for identical claims was 43 percent. “One senior executive estimated that the company’s annual cost of noise in underwriting — counting both the loss of business from excessive quotes and the losses incurred on underpriced contracts — was in the hundreds of millions of dollars,” they write.
