Cognitive bias is an error that occurs when people judge based on their thoughts and beliefs rather than facts. This can lead to wrong decisions and harm our careers, relationships, and overall mental health.

There are many types of cognitive bias, but the most common are cognitive dissonance, cognitive fluency, and the halo effect.

Cognitive dissonance is the tendency to feel uncomfortable when our beliefs and actions don’t match, and we need to find a way to make them match. This is why people tend to seek confirmation of their beliefs and reject information contradicting them.

Cognitive fluency is the ability to think quickly and logically, often used in decision-making. However, this can also lead to cognitive bias, as our emotions can influence our thoughts.

The halo effect is the tendency to judge people and things according to their most appealing features. This can be helpful, as it can help us make decisions quickly. However, it can also lead to cognitive bias, as we judge everything according to our favorite traits.

Cognitive bias can harm our careers, relationships, and mental health. It can lead to wrong decisions and can be difficult to overcome. However, learning about cognitive bias and using caution when making decisions can help us to be more successful.
