What Are Cognitive Biases?

What Are Cognitive Biases?

Cambridge English Dictionary: cognitive bias as the way a particular person understands events, facts, and other people, which is based on their own particular set of beliefs and experiences and may not be reasonable or accurate. “We are often presented with situations in life when we need to make a decision with imperfect information, and we unknowingly rely on prejudices or biases.”

Common Types Of Bias

Confirmation Bias: Making decisions based on media and information sources that are in alignment with your current beliefs.

Anchoring Bias: Becoming committed or attached to the first thing you learn about a particular subject. Similar to the halo effect , which is when you assume that a person’s positive or negative traits in one area will be the same in some other aspect of their personality.

Hindsight Bias: Inclination to see some events as more predictable than they are; also known as the “I knew it all along" reaction.

Misinformation effect: Memories of an event can become affected or influenced by information you received after the event occurred. Researchers have proven that memory is inaccurate because it is vulnerable to revision when you receive new information.

Actor-observer bias: You attribute your actions to external influences and other people's actions to internal ones.

False consensus effect: Assuming more people agree with your opinions and share your values than actually do. This happens because you tend to spend most of your time with family and friends, who share beliefs similar to yours.

Availability bias occurs when you believe the information you possess is more important than it actually is. This happens when you watch or listen to media sources that tend to run dramatic stories without sharing any balancing statistics on how rare such events may be.

Bandwagon effect, also known as herd mentality or groupthink: Te propensity to accept beliefs or values because many other people hold them as well. This is a conformity bias as most people desire acceptance, fearing rejection if they hold opposing beliefs. People assume an opinion is correct because many others agree with it.

Authority bias is when you accept the opinion of an authority figure because you believe they know more than you. You might assume that they have already thought through an issue and made the right conclusion. And, because they are an authority in their field, you grant more credibility to their viewpoint than you would for anyone else.

Negativity bias: Paying more attention to bad news than good. This is a natural bias that dates back to prehistoric days when noticing threats, risks, and other lethal dangers could save your life. In today’s civilized world, this bias is not as necessary.
