So many financial behavioral biases, so little time! Today, let’s take a few minutes to cover the next couple biases: pattern recognition and recency.
PATTERN RECOGNITION
What is it? Is that a zebra, a cheetah, or a light breeze moving through the grass? Since prehistoric times when our ancestors depended on getting the right answer, right away, evolution has been conditioning our brains to find and interpret patterns – or else. That’s why, our pattern-seeking impulses tend to treat even random events (like 10 coin flips, all heads) as if they’re orderly outcomes suggesting a predictive pattern. “Just as nature abhors a vacuum, people hate randomness,” says Zweig, as a result of our brain’s dopamine-induced “prediction addiction.”
When is it helpful? When we stop at red lights and go on green, we’re making excellent use of pattern recognition. Is your spouse or partner giving you “that look”? You know just what it means before they’ve said a single word. And whether you enjoy a good jigsaw puzzle, Sudoku, or Rubik’s Cube, you’re giving your pattern recognition skills a healthy workout.
When is it harmful? Speaking of seeing red, Zweig published a fascinating piece on how simply presenting financial numbers in red instead of black can make investors more fearful and risk-averse. That’s a powerful illustration of how pattern recognition can influence us – even if the so-called pattern (red = danger) is a red herring. Is any given stream of breaking financial news a predictive pattern worth pursuing, or is it a deceptive mirage? Given how hard it is to tell the difference until hindsight reveals the truth, investors are best off ignoring the market’s many glittering distractions and focusing instead on their long-term goals.
RECENCY
What is it? Recency causes you to pay more attention to your most recent experiences, and to downplay the significance of long-term conditions. For example, in “Nudge,” Nobel laureate Richard Thaler and co-author Cass Sunstein observe: “If floods have not occurred in the immediate past, people who live on floodplains are far less likely to purchase insurance.” That’s recency, tricking people into ascribing more importance to the lack of recent flooding than to the bigger context of being located on a flood plain.
When is it helpful? In “Stumbling on Happiness,” Daniel Gilbert describes how we humans employ recency to accurately interpret otherwise ambiguous situations. Say, for example, someone says to you, “Don’t run into the bank!” Whether you’re currently floating down a river or approaching a financial institution helps you quickly decide whether to paddle harder in the stream, or walk more slowly through the financial institution’s door.When is it harmful? Buying high and selling low is exactly the opposite of investors’ actual aspirations. And yet, no matter how many times our capital markets have moved through their bear-and-bull cycles, recency causes droves of investors to stumble every time. By reacting to the most recent jolts instead of remaining positioned as planned for long-term expected growth, they end up piling into high-priced hot holdings and locking in losses by selling low during the downturns. They allow recency to get the better of them, and their most rational, evidence-based investment decisions.
Now you're on the home stretch of the series on behavioral biases. Look for the rest of the alphabet tomorrow.
