Why Smart People Do Dumb
The Psychology of Stupidity
by Jean-François Marmion (Editor)
Psychology/Philosophy
TL;DR
This book ain't about making you feel smart; it's about spotting the dumb traps we all fall into. It breaks down how our brains are wired for face-palming decisions, why groupthink is a mind-killer, and how ego inflates our stupidity. You'll learn to dodge cognitive biases like a pro, question everything (especially yourself), and maybe, just maybe, stop being a walking meme of bad choices. It's a survival guide for navigating a world full of brain farts, including your own.

Key Chapter
Chapter - Why Your Brain's Wi-Fi Drops When It Matters Most
Ever wonder why you make the dumbest decisions when you're stressed or tired? This chapter spills the tea on how our mental energy, or lack thereof, turns us into walking face-palms. It's like your brain's battery is at 2% and you're trying to run a complex app – it just crashes. We often default to lazy thinking when our mental resources are low, leading to impulsive, illogical choices. Understanding this helps you realize that sometimes, the best move is to recharge your brain before making big calls, rather than pushing through with a half-dead CPU. It's about recognizing when your internal 'dumb-o-meter' is about to hit red.
Key Methods and Approaches
The Echo Chamber Escape
(AKA: Cognitive Dissonance Deflection)
Description:
How to stop your brain from only listening to itself and people who agree with it.
Explanation:
Your brain hates being wrong more than a cat hates baths. So, when new info challenges your beliefs, it's like your brain puts on noise-canceling headphones and screams, 'LALALALA I CAN'T HEAR YOU!' This method is about ripping those headphones off and actually listening to different perspectives, even if they make your brain itch. It's uncomfortable, like wearing socks with sandals, but necessary for growth.
Examples:
Actively seeking out news sources that challenge your political views instead of just doom-scrolling your usual feed.
Having a respectful debate with someone who thinks differently, instead of just blocking them on social media.
Admitting you were wrong about something, even if it means your ego takes a tiny hit.
