1The human brain is a remarkable machine, yet it makes predictable mistakes when judging people and situations.
2Psychologists call these systematic errors cognitive biases, and every single one of us carries them around.
3One famous example is confirmation bias, our habit of noticing only evidence that supports what we already believe.
4If you think a colleague is lazy, you will remember every late arrival and forget every early morning.
5Another common bias leads us to trust confident speakers far more than careful and honest ones.
6These mental shortcuts evolved because quick decisions once helped our ancestors survive in dangerous and unpredictable environments.
7In modern life, however, the same shortcuts can quietly distort our choices about money, health, and relationships.
8We cannot remove our biases completely, but we can train ourselves to notice them more often.
9Simple habits help a great deal, such as regularly asking what evidence would change my mind.
10Seeking out people who disagree with us is uncomfortable, but it protects us from our own blind spots.
11Clear thinking is not a talent; it is a discipline that rewards anyone willing to practice it.
