Cognitive Bias

Cognitive Bias Definition

Cognitions are the mental processes of thinking, planning, problem-solving, and remembering. Biases are preconceived ideas, beliefs, or opinions that may or may not be true. Cognitive biases are a combination of these two! Let's take a look at the definition of cognitive bias and some examples of cognitive bias at work.

Cognitive Bias Definition

Cognitive biases are decisions or responses based on personal perspectives or opinions rather than facts or the perspectives of others. We can make decisions based on cognitive biases without even realizing it, and we can form mistaken beliefs or make bad decisions because of our biases.

There are two main types of cognitive biases in psychology that involve the unconscious and conscious mind. Implicit bias involves unconscious thought processes that unknowingly inform our decisions. Explicit bias involves conscious thought processes that we can control. However, we can become aware of our implicit biases and learn to counteract them.

Cognitive Bias Examples

Other common cognitive biases include overconfidence bias, confirmation bias, self-serving bias, and hindsight bias.

Overconfidence Bias

Overconfidence bias happens when someone bites off more than they can chew. At first, someone with an overconfidence bias might think they are capable of completing way more than they can due to irrational judgment or pride. Someone with an overconfidence bias might take on too many tasks at a time, but they believe they can complete all of the tasks really well as if they are the best fit for the task.

Confirmation Bias

Confirmation bias, also known as the backfire effect, is when someone tries to reinforce their beliefs with existing supporting evidence. Confirmation bias can be used as a way to ignore information that goes against a person's belief. This is common when we examine news sources. Someone who feels strongly about politics might choose to only listen to the news station that supports their existing beliefs.

Self-Serving Bias

Self-serving bias is when we attribute successes to our personal efforts so we can feel good about ourselves. When something goes wrong, we blame the outcome on factors unrelated to us so that we don't feel bad about ourselves. If you score during a soccer game, you may inadvertently attribute your success entirely to yourself, even if other teammates helped you score.

Your self-serving bias reinforces your thoughts about how well you played during the game. If you don't score during the game, you might blame the lack of scoring on an outside factor like another player or the referee. When someone performs well, they tend to use the self-serving bias, but if something goes wrong, they tend to blame it on something or someone else.

Hindsight Bias

Hindsight bias is confirming that you knew something was going to happen after it has happened. "I knew it! I knew they would win!" Hindsight bias uses factual information to confirm your past prediction about an outcome. It feels good to claim that we knew it would happen like that, and we're all familiar with the phrase "I told you so." In reality, we didn't know that it would happen. We only predicted it, and we could have been wrong.

If we do turn out to be wrong about a prediction, we may just forget about our prediction and focus on something else. Hindsight bias is really a subtype of self-serving bias. If we turn out to be right, we celebrate it! If we turn out to be wrong, we blame it on outside factors. "It should have happened differently." "I would have been right if that one guy had played better."

Cognitive Dissonance and Bias

Cognitive dissonance is when two or more beliefs that you hold conflict with each other. One or more of those beliefs may be based on a cognitive bias. You might hold the belief that everyone should eat healthily, but you might also hold the belief that everyone should indulge in treats. These two beliefs conflict when your indulgence in a favorite treat turns into an unhealthy eating pattern.

If someone is experiencing cognitive dissonance, they may become upset, frustrated, or irritated when they are offered information that challenges their existing beliefs. Dissonance can also happen when you set a goal but then engage in behaviors that go against the goal you set, like the example at the beginning!

Cognitive Biases in Decision Making

Cognitive biases directly influence our decision-making. We are unaware of them much of the time, especially since some of them are unconscious. Cognitive biases protect us in some situations, but they can also have negative consequences. They can keep us from trying new things, considering other viewpoints, and excelling in our careers.

One way cognitive biases impact our decision-making is through problem-solving. Problem-solving involves overcoming a variety of obstacles to find a solution. Sometimes our biases in reasoning prevent us from finding a solution to a problem. We fixate or only focus on one point of view relevant to our beliefs.

Our ways of reasoning might work to solve problems the first couple of times. Eventually, we run into a different type of problem that needs a fresh perspective. When we tend to fixate on one way to solve a problem and use it for everything, it is called a mental set.

Cognitive biases play a role in many different situations, and they aren't always harmful. Sometimes, our biases let us know when we are in danger. Think about a time when you had to make a quick decision. You most likely made the decision based on emotions or past knowledge.

Maybe you avoided a certain part of town because you remember a friend saying that they didn't like it years ago. Your reasoning might be based on past feelings or impressions stored in your long-term memory. The quicker you have to make a decision, and the less self-reflection and critical thinking skills you use, the more biases will likely influence your decision.

Group Differences and Bias

Have you ever wondered why people are so different from one another? Sure, genetics and culture play a part in our differences. However, group differences are often due to our biases about certain topics. You have probably been a part of a group of people similar to you or with minor differences. We often use in-group bias to favor the opinions of our friends or people similar to us.
