Reject Your Cognitive Bias in Decision-Making

All of us have significant preferences that we don’t consciously see or understand. Although we don’t intend it, these cognitive biases significantly impact the way we make decisions. Because most leaders are very confident people, we tend to underestimate or ignore the power these biases have in our lives. This can be incredibly detrimental to our decision-making processes.

Bias in decision-making is a widespread problem, but once we become aware of it we can work to overcome it. Here’s what you need to know about common biases and errors in decision-making. 

What Is Cognitive Bias?

To put it simply, a cognitive bias is an error in your way of thinking that affects the way you make decisions. We’re often not aware of these biases; in fact, they can strike when we feel most confident in our ability to decide fairly, which is why cognitive bias is sometimes referred to as “decision bias.” 

According to some theorists, more than one hundred types of cognitive biases have been identified. There may be many types of biases in decision-making that leaders should be aware of, but here are seven that are crucial to know. 

1. Framing Bias

This bias, as the name suggests, has to do with how a decision is framed. Regardless of the actual data, people tend to make decisions based on whether a certain option is presented to us as being positive or negative. 

One example of this would be reviewing year-end data. If the data is juxtaposed with last year’s lower numbers, the year will look like a great success. However, if this same data is compared with projections that you did not meet, the year will look much less profitable. Don’t be fooled by the way the data is presented to you: focus on the numbers themselves.

2. Overconfidence Bias

Overconfidence bias is much like it sounds: the fact that people tend to be much more confident about their own ability to make decisions than they should be. This is especially a problem among business leaders, who tend to be a confident lot. 

The best way to adjust for overconfidence bias is to humbly acknowledge that you don’t have all the answers. Keep an open mind and acknowledge that you might be wrong. While confidence is a key trait in a leader, hubris is much less becoming. 

3. Confirmation Bias

Humans tend to not want to change their existing beliefs. Confirmation bias causes us to subconsciously ignore evidence that goes against the beliefs we currently have. For example, if we have a problem employee, we might automatically fixate on the things they do wrong because it confirms our view that this employee is a poor performer. 

On the other hand, if we have a star employee, we’re much more likely to overlook their mistakes because they go against what we want to believe. Outside of the workplace, many people choose their news outlet of choice based on whether it supports their current political beliefs, or attend a church that aligns most correctly with their worldview. 

It’s important to remain objective and evaluate all evidence on a case-by-case basis in order to make the best decisions.

4. Randomness Bias

Randomness bias is our tendency to notice patterns in random data that simply don’t exist. The most common example of this is seen in gamblers, who make bets based on such patterns or superstitions when the odds are truly random. Don’t try to reach for evidence that isn’t there. Allow for the possibility of random data, even when it’s not convenient for your bottom line.

5. Availability Bias

Availability bias is the tendency for our minds to look for the most readily available evidence to back up our decision-making. It’s a great tactic to compare your current situation to previous, similar examples in order to make the best choice. However, availability bias is far from objective. 

When it comes to availability bias, your mind focuses on the evidence that stands out most in your mind. Unfortunately, it’s outliers that tend to be more memorable than averages. When making a decision, be sure you’re basing your choice on concrete numbers and not just the ones you’re able to remember most quickly.  

6. Anchoring Bias

Anchoring bias is our tendency to place undue weight on the first piece of information we see. For example, if you’re buying a new car and the first one you look at is incredibly expensive, the cars you see after that will seem reasonable and affordable in comparison, regardless of whether they are actually fairly priced.

7. Hindsight Bias

 We’ve all heard the phrase “hindsight is 20/20.” Hindsight bias is a phenomenon that makes us think a past event was, in hindsight, more predictable than it actually may have been. This can lead to us being too hard on ourselves for not predicting outcomes that could not have been foreseen, simply because they seem obvious to us now in the present. 

How to Overcome Cognitive Bias

In a way, a cognitive bias is our brain’s way of streamlining the decision-making process. By eliminating evidence that doesn’t seem to apply and drawing connections between the patterns we observe, it seems like we’d be able to make a logical, confident decision.

However, we can’t fall victim to cognitive bias. These errors in the thought process prevent us from accurately judging data and making decisions in a fair and objective manner. 

The best way to overcome cognitive bias is to take your time with the decision-making process. Consider all evidence and examine your first instinct to see if there might be some hidden influences that affect your perception of the situation. You’ll find that accepting the existence of cognitive bias is the first step to overcoming it. 

Decision-making biases and errors in management are closely related. If you allow cognitive bias to dictate the way you make decisions, you’re bound to make mistakes. Fortunately, with a little awareness and a lot of practice, these errors can be greatly reduced.
