Understanding Human Behavior
Like Duolingo, but for Understanding Human Behavior. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
24 levels across 3 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through Making Sense of Everyday Actions, The Social Animal, and The Underlying Biology and Mental Health. It starts from scratch.

Key ideas in Understanding Human Behavior
- Heuristics evolved as mental energy savers for quick decision-making
- Heuristics work well most of the time but fail predictably in specific situations
- Using shortcuts is an automatic cognitive trait shared by everyone, not a sign of low intelligence
- People selectively notice and remember information confirming what they already think
- Conflicting evidence is overlooked, dismissed, or actively forgotten
- Confirmation bias reinforces beliefs even when the actual evidence does not support them
- Vivid or recent events come to mind quickly and feel much more common than they are
- Emotional intensity makes an event more accessible to recall than dry statistical risk
- Ease of recall gets mistaken for statistical probability
- The first number encountered acts as a psychological magnet for later guesses
- Adjustments away from an initial anchor are almost always too small
- Anchoring takes effect even when the starting number is totally arbitrary
- People easily identify irrational shortcuts and biases when watching others make decisions
- People assume their own thoughts and decisions are objective and evidence-based
- Introspection cannot reveal one's own unconscious biases
- Memory pieces together fragments, assumptions, and current emotions rather than playing back recorded footage
