New Research - How to Help Clients Make Better Decisions

Making decisions is not something human beings are very good at. We do a poor job of predicting what will make us happy in the future, we often misjudge our ability to handle risk, and our decisions are plagued by subtle biases that throw us unwittingly off course. Because the essence of financial planning is making decisions about the future, it’s critical that clients and advisors understand how decision-making biases can be identified and overcome.

The latest research in psychology, behavioral economics and neuroscience has underscored these decision-making frailties. But, rather than be discouraged by the challenge this poses, advisors should embrace our constantly improving understanding of how decisions can go awry for what it is: an opportunity to face up to the uncertainty and complexity and to improve the decision-making as best we can.

I'll focus on research on three important topics that are at the core of good financial planning: cognitive biases that most affect financial decision-making; problems with risk-tolerance assessments; and what we understand – or don’t – about what will make us happy.

How biases affect financial decision-making

If there were a Bible of the frailties of decision-making, it would be Daniel Kahneman's 2011 book, Thinking Fast and Slow, where he discusses biases, which he defines as "systematic errors in decision making." Since financial advice is about decision-making, Kahneman's research, showing that much of our decision-making is beset by these systematic errors, does not offer much good news.  His book, which was reviewed by Laurence Siegel in Advisor Perspectives in June, offers a rich discussion of the various errors and biases his work and others’ have identified. I'll highlight a few of the most important here.

Central to the book is Kahneman's description of two different types of thinking the brain does:

  • System 1, which "operates automatically and quickly, with little or no effort and no sense of voluntary control"
  • System 2, which "allocates attention to effortful mental activities that demand it, including complex computations"

System 1 performs simple calculations (you can see 2 x 2 and know the answer in an instant), while System 2 is called upon to tackle more complex problems (you’d be calling on this one for, say, 17 x 24). Overreliance on System 1 underpins many biases. Kahneman uses the term WYSIATI (what you see is all there is) and talks about how System 1 often assumes a coherent, complete picture from incomplete information, making bad decisions as a result.

For example, Kahneman discusses the optimistic bias, which leads to overconfidence. For its far-reaching consequences, Kahneman declares that this “may well be the most significant of the cognitive biases." The propensity for System 1 to unconsciously construct seemingly coherent cause-and-effect models based on the past is what gives rise to overconfident predictions of the future.
