Book summary
When you’re truly prone to consistent biases and mental shortcuts, a clever but scientific takedown of the illusions your brain generates will help you believe you’re rational, in control, and exceptional.
Key Delusions & Biases Exposed: Incompetent people overstate their ability.
For instance, consider the tone-deaf singer who isaf singer who is trying out for American Idol.
Reality check: you sound more confident the less you know.
2. Confirmation Bias: You look for proof to support your convictions.
Research indicates that people tend to overlook facts that contradict their political beliefs.
Fix: Look actively for counterarguments.
3. The Spotlight Effect: Everyone points out your shortcomings—bad hair day, embarrassing joke.
Truth: People worry about themselves far too much.
4. Basic Attribute Error
Delusion: While excusing your own as situational, criticise others’ behaviour as moral failings.
For instance, “That driver cut me off because he’s a jerk (not because he’s rushing to the hospital).”
5. The Halo Effect: Beautiful/charismatic people seem to be smarter or more competent.
Studies show that CEOs are taller than usual; height is unconsciously connected with leadership.
6. Choice-Supportive Bias: Arguing for past choices—even poor ones—to prevent regret.
Ask: “Would I choose this again today?” Life Hack
7. The Texas Sharpshooter Fallacy: Observing “lucky streaks”—patterns in randomness.
For example, a psychic may claim to have predicted a vague event only after it has already happened.
8. Believing people “deserve” their misfortune, one falls into the just-world fallacy illusion.
Danger: Attaching blame for poverty or disease.
Spotting these prejudices helps you be less susceptible (to ads, politicians, your justifications).
Better decisions result from challenging your instincts.
