How Cognitive Bias Costs you Money

Cognitive bias is an unconscious part of our thinking process. Because life is complicated, we tend to develop shortcuts in our thinking that lead us to make potentially illogical judgments or decisions because we’re subconsciously unable to see the full picture. Without knowing that it’s happening, we become so clouded by certain ingrained assumptions that we lose the ability to be truly objective and free from prejudice.

We all have some biases that influence our decisions. When it comes to your finances, these biases could end up costing you a lot of money.

Common Biases that Cost you Money

Biases tend to operate in packs. You’ll often find that your decisions are driven, in large part, by a variety of corresponding biases.

Status Quo Bias

Status quo bias is the tendency to keep doing what you’re already doing. You’re comfortable with how things are and the choices you’ve made in the past, so you become biased towards the familiar.

This often turns into a form of brand loyalty – you may find yourself repeatedly buying from a small circle of companies not because their products are the best or are even the right fit for you, but because those are simply the companies you’ve purchased from in the past.

Confirmation Bias

Confirmation bias is when you go looking for answers, except you already “know” the answers, so what you’re really looking for is information that confirms what you already believe to be true.

Confirmation bias impedes your ability to make objective choices. If you like shopping at Best Buy, for example, because that’s where you’ve always shopped (status quo bias), you’ll be more apt to pay attention to information that supports the idea that shopping at Best Buy is a good thing, and less receptive to information that suggests otherwise.

Self-Serving Bias

Self-serving bias, meanwhile, is the tendency to think that good things happen because of choices you’ve made, while bad things happen for reasons outside of your control. When you end the month with a financial surplus, that’s because you had made a great plan and executed on it. When you come up short for the month, that’s because something came up and there really wasn’t anything you could have done about it.

The reality, of course, is somewhere in between. But by giving yourself too much credit for the good and not enough blame for the bad, you never really understand or accept that you need help or that things need to change.

Breaking Free from Your Biases

There are quite a few different biases out there, but ultimately, from a personal finance perspective, the big problem with cognitive bias is that it prevents you from learning and improving. When you’re prejudiced to make certain decisions, you unnecessarily close yourself off from other options and possibilities that may potentially be better for you.

There’s a reason advertisers are keenly aware of the effect cognitive bias has on an audience. By manipulating your subconscious biases, advertisers get you to make choices that aren’t in your best interest (even if you think they are). So take a moment to think about your particular biases and how they impact the way you handle your money. Why are you making the choices that you’re making? Are you allowing yourself to see the full picture?

Start by simply challenging some of the daily assumptions that fuel your spending habits:

  • Why do you shop at one store and not another?
  • What are the factors you point to when you justify your financial decisions?
  • Why are those factors important?
  • Where else could those factors be satisfied?
  • What other factors might be more important? 

Bias plays an undeniable part in how we think and how we make decisions. You don’t have to change everything about your tendencies, but you should strive to be aware of the real reason why you make the choices that you do. Every spending, saving, and investing choice you make is important. The least you can do is give yourself all the facts.
