Summary of "Why People Are So Confident When They're Wrong"

Key Wellness Strategies, Self-Care Techniques, and Productivity Tips from the Video

Calibrate Your Confidence

Track and keep score of your predictions and estimates to better understand your accuracy.
Instead of making absolute promises (e.g., “I’ll do it by Friday”), express your confidence probabilistically (e.g., “There’s a 60% chance I can get it done by Friday”).
Intellectual humility is crucial—acknowledge that you might be wrong or uncertain.

Seek and Use Feedback

Regular, clear feedback helps improve calibration of confidence.
Feedback that challenges your assumptions helps reduce overconfidence.

Listen to Others, Especially Critics

Engage with people who disagree with you to understand their perspectives and information.
This helps uncover blind spots and improves decision-making.

Know the Limits of Your Knowledge

The best calibrated people are those who understand what they don’t know.
Wisdom lies in recognizing the limits of your certainty rather than being overly sure.

Use Group Wisdom

Capitalize on the “wisdom of the crowd” by consulting others and combining multiple viewpoints.
This reduces individual biases and overconfidence.

Be Aware of Cognitive Biases and Mental Shortcuts

Understand that your brain uses heuristics that can lead to overconfidence.
Recognize when you might be substituting easier questions for harder ones (e.g., judging happiness based on recent events rather than overall life satisfaction).

Manage Mental Load

Overconfidence can increase when working memory is overloaded.
Break down complex information into manageable chunks to avoid cognitive overload.

Practice Intellectual Humility

Accept that being confident does not always equate to being correct.
Be open to revising your views based on new evidence.

Use Tools and Games to Improve Calibration

Engage in activities like trivia games where you must state your confidence level along with your answers.
Such tools encourage reflection on how sure you are and help improve calibration over time.
