Scarcity by Sendhil Mullainathan and Eldar Shafir Summary
Overview of Scarcity
"Scarcity" reveals why having too little reshapes our minds, decisions, and lives. Challenging conventional wisdom that failure causes poverty, Mullainathan and Shafir argue the reverse: scarcity itself creates failure. What if your empty wallet is actually emptying your mental bandwidth?

Why Your Smartest Friend Makes the Dumbest Decisions
Picture a firefighter racing toward an emergency, mind laser-focused on equipment checks and rescue protocols. Yet in this heightened state of readiness, 79% forget one critical safety measure: buckling their seatbelt. Vehicle accidents are the second leading cause of firefighter deaths, but when the alarm sounds, this simple act vanishes from awareness. This isn't carelessness-it's the paradox of scarcity at work. Whether you're racing against a deadline, stretching your last twenty dollars until payday, or a dieter obsessing over forbidden chocolate cake, you're experiencing the same psychological force. Scarcity-having too little of what you need-doesn't just limit resources. It fundamentally rewires how your brain processes information, makes decisions, and perceives the world. This insight explains puzzles that have baffled economists and psychologists for decades: Why do the busiest people keep taking on more? Why do smart people make shortsighted financial choices? Why does poverty seem to perpetuate itself regardless of individual talent or effort?
