How to Outsmart Your Own Brain: Scientific Thinking

The Evolutionary Basis of Bias00:00:00

Humans have evolved to use pattern recognition and mental shortcuts (heuristics) to survive and solve problems efficiently. While these shortcuts are useful for avoiding immediate dangers, they often lead to cognitive biases when applied to complex or abstract topics.

The video highlights 'availability bias,' where our judgment is skewed by easily recalled information (like news of plane crashes), and 'confirmation bias,' where we favor information that aligns with our existing beliefs, such as the persistent but unscientific myth of learning styles.
