Cognitive Biases

Cognitive Biases

Cognitive biases are systematic patterns of deviation from rationality in judgment, often caused by heuristics, emotions, and situational factors.

THE IDEA

Cognitive Biases

We can overestimate our ability to think rationally and objectively. Cognitive biases are systematic patterns that can distort our judgments. Mental shortcuts help us reach decisions quickly, especially when time is limited, but can also lead us astray. Situational pressures, motivations, and emotions can influence judgment too.

Recognizing a possible bias gives us a reason to examine a decision more closely. Awareness alone does not settle whether a particular judgment is sound.

When to use it

  • When analyzing a financial investment, being aware of overconfidence bias can help you seek more disconfirming evidence.

  • During a performance review, understanding the halo effect can prevent a single positive trait from overshadowing other aspects.

  • In team discussions, knowing about groupthink can encourage you to actively invite dissenting opinions.

FROM THEORY TO EVERYDAY LIFE

In practice

01

Everyday Decision-Making

When choosing between two job offers, you might overestimate your ability to be objective while ignoring how your emotional attachment to one role biases your reasoning.

✳

A MOMENT TO REFLECT

Put it to work.

  1. Can you recall a recent decision where your confidence in your rationality may have been overblown? What bias might have been at play?

  2. How can you create a habit of pausing to question whether a heuristic or situational factor is influencing your judgment?

  3. In what ways does recognizing cognitive biases in others help you see them more clearly in yourself?
