Daniel Kahneman was an Israeli-American psychologist of the 20th–21st century; author of Thinking, Fast and Slow and co-founder of behavioral economics; hook: Nobel Prize in Economics (2002). He showed that people are not purely rational thinkers – intuition and cognitive biases often drive decisions. His work reshaped economics, law, policy, and business, making him one of the most influential thinkers of our time.
📚 Born in Tel Aviv in 1934, he spent much of his childhood hiding in Nazi-occupied France. ⚔️ His father died during the Holocaust, shaping his lifelong interest in human vulnerability. 🎓 Studied psychology in Jerusalem and later taught at Princeton University. 🤝 Collaborated with Amos Tversky in the 1970s, a partnership that revolutionized economic thought. 📖 Their Prospect Theory showed that people fear losses more than they value gains. 🏆 In 2002, he won the Nobel Prize in Economics – exceptionally rare for a psychologist. 💡 His book Thinking, Fast and Slow (2011) became a global bestseller, popularizing decades of research. 🌍 His concepts like “framing,” “anchoring,” and “availability heuristic” are now part of everyday language. 📊 His work influenced governments in designing “nudge policies” to guide better decisions. 🧠 He admitted that even he still fell prey to the very cognitive illusions he studied. 🌟 Friends recalled his humor – he once joked that if people actually became rational, he’d be out of a job. 😄 A curious note: despite fame, he preferred modest dinners with colleagues to big conferences.
