CURSE: Knowledge and Hindsight Bias

By Staff Reporters

***

***

Similar to the availability heuristic (Tversky & Kahneman, 1974) and to some extent, the false consensus effect, once you really understand a new piece of information, that piece of information is now available to you and often becomes seemingly obvious. It might be easy to forget that there was ever a time you didn’t know this information and so, you assume that others, like yourself, also know this information: ie., the curse of knowledge.

However, it is often an unfair assumption that others share the same knowledge.

And so, the hindsight bias is similar to the curse of knowledge in that once we have information about an event, it then seems obvious that it was going to happen all along.

IOW: I should have seen it coming!

Dr. Richard H. Thaler and Behavioral Economics

A behavioral scientist

By Rick Kahler MS CFP®

Human beings make most of our decisions—including financial ones—emotionally, not logically. Unfortunately, too much of the time, our emotions lead us into financial choices that aren’t good for our financial well-being. This is hardly news to financial planners or financial therapists. Nor is it a surprise to any parent who has ever struggled to teach kids how to manage money wisely.

Economic Model Assumptions

Yet many of the economic models and theories related to investing are based on assumptions that, when it comes to money, people act rationally and in their own best interests. There’s a wide gulf between the way economists assume people behave around money and the way people actually make money choices. This doesn’t encourage financial advisors to rely on what economists say about financial patterns, trends, and what to expect from markets or consumers.

2017 Nobel Prize in Economics

It’s significant, then, that the 2017 Nobel Prize in Economics went to Dr. Richard H. Thaler, professor of behavioral science and economics at the University of Chicago Booth School of Business. Dr. Thaler’s work has focused on the differences between logical economic assumptions and real-world human behavior. His research not only demonstrates that people behave emotionally when it comes to money; it also shows that in many ways our irrational economic behavior is predictable.

This predictability can help advisors and organizations find ways to encourage people to make financial decisions in their own better interest. The book Nudge, by Dr. Thaler and Cass R. Sunstein, describes some of those methods.

Example:

One example is making participation the default option for company retirement programs like 401(k)’s. Employees are free to opt out, of course, but they need to actively choose to do so.

A second example is the “Save More Tomorrow” plan, which offers employees the option of automatically increasing their savings whenever they receive raises in the future.

Both of these examples rely on a predictable behavior—human inertia. Most of us tend to postpone, ignore, or forget to take action even when that action would be good for us. So if a system is set up so not taking action leaves us with the choice that serves us better, we are “nudged” toward helping ourselves toward a healthier financial future.

Integration

As one of the pioneers in integrating the emotional aspect of money behavior into the practice of financial planning, I’ve long since come to understand that managing money is about much more than numbers. The world of investing may seem to be cold and calculating, but it’s actually driven by emotions. I’m familiar with the work of researchers who have demonstrated that some 90% of all financial decisions are made emotionally rather than logically.

I was pleased in 2002 when one of those researchers, psychologist Daniel Kahneman, won the Nobel prize in economics for his studies of human behavioral biases and systematic irrational behaviors. (That research was done jointly with psychologist Amos Tversky, who died in 1996.)

I’m even more pleased to see the economics Nobel prize go to a behavioral researcher for the second time. Maybe the realm of economics is beginning to integrate the untidy realities of human emotions into its theories. Eventually, this might lead to new economic models that take into account the emotions that shape people’s money decisions and the fact that money is one of the most emotionally charged aspects of our lives.

Assessment

Perhaps economists are beginning to appreciate the truth of the statement Dr. Thaler made at a news conference after his prize was announced. “In order to do good economics, you have to keep in mind that people are human.”

RIP: Daniel Kahneman PHD

NOBEL PRIZE WINNER AND FATHER OF BEHAVIORAL ECONOMICS

By Staff Reporters

DEFINITION: According to Wikipedia, behavioral economics is the study of the psychological, cognitive, emotional, cultural and social factors involved in the decisions of individuals or institutions, and how these decisions deviate from those implied by classical economic theory.

Behavioral economics is primarily concerned with the bounds of rationality of economic agents. Behavioral models typically integrate insights from psychology, neuroscience and microeconomic theory. The study of behavioral economics includes how market decisions are made and the mechanisms that drive public opinion.

Behavioral economics began as a distinct field of study in the 1970s and ’80s, but can be traced back to 18th-century economists, such as Adam Smith, who deliberated how the economic behavior of individuals could be influenced by their desires.

The status of behavioral economics as a subfield of economics is a fairly recent development; the breakthroughs that laid the foundation for it were published through the last three decades of the 20th century. Behavioral economics is still growing as a field, being used increasingly in research and in teaching.

Daniel Kahneman PhD, the father of behavioral economics, died yesterday at age 90 years old. He’s best known for applying psychology to economics and uncovering biases and mental shortcuts that make people act irrationally, as he chronicled in his best-selling book Thinking, Fast and Slow.

Kahneman, along with his long-time collaborator and friend Amos Tversky PhD, developed “prospect theory,” or loss-aversion theory, which earned him the Nobel Prize in Economics in 2002 (which he shared with fellow economist Vernon Smith). The idea is that people value losses and gains differently, so we feel more bad about losing $100 than we feel good about making the same amount. He applied this theory to investors, who had previously been considered rational decision-makers. It shows up elsewhere, too—for example, golfers putt better when they’re facing the loss of a stroke than when they might gain one.

Two other biases he identified include:

  • The “peak-end rule” that people remember an experience primarily based on how they felt at its most intense moment and the final part of it. It’s why you consider a whole vacation good if the last day was good—or the opposite.
  • The conjunction fallacy where people erroneously think the probability of two things being true is more likely than just one thing, which the famous “Linda the Bank Teller” problem illustrates.
