What Cognitive bias means in practice
In real life, cognitive biases mean you might trust a friend’s opinion more than data, assume people from another culture are 'different' instead of 'normal,' or stick with a bad plan because you’ve invested time already. They’re not flaws—they’re survival tools that sometimes backfire in modern decision-making.
