Why Behavioral Economics Matters to Your Financial Health
People too often end up regretting financial decisions they made in the past. Not every decision, but enough to be disconcerting.
This has negative long-term consequences. It can erode people’s confidence in their ability to make good financial decisions and lead to avoidance behaviors in which individuals ignore them to harmful effect. In order to understand and combat this, we need to understand behavioral economics.
What is Behavioral Economics?
Behavioral economics involves understanding psychological issues associated with financial decision-making. Giving consideration to these issues and learning about financial concepts should lead to better decisions.
It isn’t an exact science and the field is relatively new, so there is much yet to learn.
Still, traditional economic models in which individuals make perfectly rational decisions based upon knowledge and data fall far short. They don’t even begin to explain the messes that many people make of their finances. Nor do they explain the prevalent disinterest, apathy, or dislike of financial matters.
When you introduce psychology into a rational field like economics, all hell breaks loose. One issue in dealing with the intersection of science and our lives is that of what is normal or average. Science, in some cases, can tell us what a typical person does in a situation. It can paint a clear picture of actions and outcomes. Individuals, however, are never the exact average. On an individual level, our decisions and biases defy prediction.
The good news is that we don’t need science to predict our behavior. We do need for science to inform us about how we trick ourselves when it comes to financial decision-making. We need to understand how to take our own worst enemy — our behavior — out of the equation. Or at least how to reduce its impact.
For the most part, humans don’t make rational financial decisions. If we did, then there would be no bubbles and there would be no busts. Instead, emotion frequently overrides logic. While this may add interest and spice to many areas of life, it tends to have a negative effect on our finances. Here is how to deal with some of our most common errors of irrationality:
1. Loss Aversion
Loss aversion leads to over-holding. In other words, reluctance to accept an investment loss can lead to further losses. The rational decision is to employ your capital where it has the best potential. The emotional choice is to hold a losing asset in hopes that it will “come back.”
If it isn’t the best place to have your money today, dump it. Move the money where it will work for you.
2. Overweighting and Underweighting Probabilities
Investors often tend to overweight small probabilities and underweight large ones.
Interestingly, this can lead not only to a decision to buy things that you shouldn’t buy, but also to not buy something that you should.
For example, let’s say that an investment has a small probability of gain and a large probability of loss. Overweighting the small probability of gain while underweighting the big probability of loss increases the odds of selecting this poor investment choice.
Alternatively, let’s say that the probabilities are reversed, and the investment has a low probability of loss and a high probability of gain. It’s the proverbial no-brainer. Yet overweighting the small probability of loss and underweighting the large probability of gain decreases the likelihood of selecting this appropriate investment.
Step back — try to be objective and realistic.
3. Herd Mentality
Naturally, we see this one in others — not us! For some reason, large groups of people often believe what is too good to be true. After all, everyone else believes it! This leads to things like the internet bubble.
Don’t join the herd. Herds go over cliffs.
If you are somehow with the herd, be very careful. It will be too late to back up once you’ve gone over the edge.
4. Recency Effect
This is one of my favorites. We are imprinted with our most recent success or failure. We believe it will happen again. This is similar to the primacy effect, in which the earliest event carries more mental significance than events that occurred later.
But whether your last investment was a boon or a bust has no impact on the next one. Evaluate your investments on their merits, not on your emotions.
A Final Thought
The keys to financial success are knowing ourselves and behaving in our own best interests even when our gut tells us to go another direction.
Perhaps future advances in behavioral economics will help with social and financial problems, such as many individuals’ inability to delay gratification in order to invest in their futures. Perhaps we’ll even find the key to allowing everyone to understand that they themselves hold the largest influence over their financial future. Gaining financial knowledge and making appropriate financial decisions can change your world.
