Key Takeaways
- Cognitive biases can mislead us, impacting our decision-making and leading to incorrect conclusions.
- Heuristics are mental shortcuts that help us process information quickly but can also create cognitive biases.
- Five key types of cognitive biases include negative bias, recency bias, anchoring bias, self-serving bias, and familiarity bias.
- Understanding these cognitive biases is essential for making better decisions.
- Awareness of cognitive biases allows us to recognize their influence and improve our judgment.
Our brains can process a great deal of information through the five senses: sight, hearing, taste, touch, and smell.
There are about 100 billion neurons (the fundamental units of the brain) in a human brain.
Despite how powerful our brains are and how much data we can process, we still need shortcuts.
These mental shortcuts, called heuristics, help us solve problems and make judgments quickly and efficiently.
These mental shortcuts help us avoid becoming stuck in decision-making.
They allow us to function without pausing to consider the next task. They shorten your decision-making time.
Your mental shortcuts can lead to a cognitive bias. This is an error in your thinking when you are processing and interpreting information. These biases impact your decision-making and judgments.
Cognitive biases are mechanisms that help the brain simplify information processing. They sometimes distort our decision-making and lead us to draw false conclusions.
These time-saving shortcuts help you overcome the flood of data that comes in through your five senses.
These incorrect conclusions can adversely affect your decisions. The key is to understand these biases and acknowledge their presence. They will help you make better decisions.
5 types of cognitive biases impact our decision-making process
Let’s discuss the five “flavors” of cognitive biases so you can understand them better and how they impact your decision-making.
These cognitive biases can lead us to incorrect conclusions. It’s important to know what they are. Understand how they impact your decisions.
1. Negative Bias
A negativity bias is our tendency to give greater weight to negative information and experiences than to positive ones.
The negativity bias leads individuals to dwell on adverse events. This means you recall insults better than praise.
This bias has roots in our early days when we were trying to survive in the wild.
The amygdala is one of two almond-shaped clusters of nuclei located deep within the brain.
It is the center for our emotions, emotional behavior, and motivation.
It serves as our “early warning system” that monitors the environment for potential threats.
“Evolutionary biologists tell us we have a “negativity bias” that makes our brains remember negative events more strongly than positive ones. So when we’re feeling lost or discouraged, it can be very hard to conjure up memories and feelings of happiness and ease.” — Sharon Salzberg, a bestselling author and teacher
When the brain senses danger, it puts us on “red alert” and prepares the body to survive.
We pay more attention to negative news than to positive news. That’s why newspapers and television news outlets prefer to report negative information, as it attracts viewers and readers.
2. Recency Bias
Recency bias is the tendency to favor recent information and experiences over historical events. It gives great importance to the most recent data.
For example, an appraiser assesses an employee’s performance based on recent work instead of work undertaken during the year.
“After seeing a movie that dramatizes nuclear war, people are worried more about nuclear war; indeed, they felt that it was more likely to happen. The sheer volatility of people’s judgment of the odds — their sense of the odds could be changed by two hours in a movie theater — told you something about the reliability of the mechanism that judged those odds.” — Michael Lewis, a best-selling author
Recent bias places too much emphasis on fresh experiences in your memory, even if they are not the most relevant.
The human brain likes to use mental energy and time. It retains recent data for incidents that occurred a while ago.
Recency bias occurs in investing when investors place greater weight on short-term performance than on long-term performance.
3. Anchoring Bias
Anchoring bias is when you rely too heavily on the first piece of information you get about a topic.
When you make estimates, you use the first piece of information as an anchor. This becomes your point of reference rather than a neutral view of information.
Anchoring bias occurs when individuals rely on the first information presented rather than considering later information.
That is why it’s tough to change a first impression.
An anchoring bias is the tendency to be significantly influenced by the first piece of information we get.
For example, the first number proposed in a negotiation serves as an anchor for future talks.
4. Self-Serving Bias
A self-serving bias occurs when a person takes credit for positive outcomes. They then attribute adverse events to external factors.
Your age and cultural background can influence your self-serving bias. It is a cognitive bias with both positive and negative aspects.
A self-serving bias is a self-defense part of our personality that is distorted by the need to enhance our self-esteem.
For example, after a car accident, both drivers typically blame the other driver for causing the crash.
Another example is when you get a good grade on a test. You tell yourself that it is because you studied hard, or you know the material well.
When you get a bad grade on a test, it is the teacher’s fault, or the test was unfair. In sports, athletes attribute their success to hard work and practice.
Self-service bias is when you give yourself too much credit for your success or attribute others’ failures to you.
When you do well on a project, you attribute it to hard work. If the project doesn’t go well, you blame it on bad luck.
5. Familiarity Bias
Familiarity bias is about your tendency to prefer people who look like you.
You may also prefer those who dress like you or have a similar socio-economic background.
This bias is the preference for familiar places, people, or things over unfamiliar ones.
Familiarity bias is a cognitive shortcut that gives greater weight to trusted sources of information than to non-trusted sources. It concerns a preference for familiar details and experiences.
For example, you tend to stick to a few dishes on a menu if you are familiar with them. You also go to the same shopping places when they are known to you.
In daily life, people often take the same route to work or school. They buy a specific brand of products and services. This is because they are familiar with the directions and the brands.
Bringing it all together
Five types of cognitive biases affect decision-making. They are negative bias, recency bias, anchoring bias, self-serving, and familiarity biases.
These cognitive biases can, unfortunately, lead us to the wrong conclusions.
Thus, it is essential to understand these cognitive biases. It is crucial to know how they affect your decisions (for better or worse).
