"Nothing in life is as important as you think it is, while you are thinking about it." - Daniel Kahneman

📌 Key Takeaways - Thinking, Fast and Slow
🧠🔍🎭 System 1 and System 2: Kahneman introduces two systems that our brain uses to process information. System 1 is quick, intuitive, and emotional, while System 2 is slow, deliberate, and logical. For instance, if someone asks you to solve 2+2, you immediately know the answer (System 1). But if asked to calculate 24x17, you need to think and work it out (System 2).
📉🌐🏁 Heuristics and Biases: The book discusses common errors in judgment and decision-making due to our reliance on heuristics (mental shortcuts). For example, the "availability heuristic" is when we overestimate the likelihood of events that come to mind more easily. After seeing a plane crash on the news, we might irrationally fear air travel.
💡💣💔 Overconfidence Bias: Kahneman talks about how our System 1 often leads to overconfidence. For instance, entrepreneurs might overestimate their chances of success, underestimating the high failure rate of startups, demonstrating this bias.
🧮🧩👁🗨 Anchoring Bias: This bias refers to the influence of an initial piece of information (the anchor) in decision-making. If a store says an item is "on sale from $100 to $60," you might think you're getting a great deal, even if the item is not worth $60.
🚦⏱️🏊♀️ The Halo Effect: Our perception of someone in one area influences our perception of them in other areas. For example, if someone is attractive, we may automatically assume they are also kind and intelligent, even without evidence.
🌄🔭💭 What You See Is All There Is : We often make decisions based on the information we have at hand, neglecting what we don't know. If we see a product advertised with positive reviews, we might assume it's excellent, ignoring the potential existence of negative reviews.
🔄🔮🦋 Hindsight Bias: Kahneman discusses our tendency to believe, after an event has occurred, that we predicted or could have predicted the outcome. For example, after a football match, fans might claim they "knew all along" their team would win.
🧮💰🎁 Prospect Theory: This theory, developed by Kahneman and Tversky, explains how people decide between alternatives that involve risk, like in economic decisions. For example, people are generally more willing to take risks to avoid a loss than to achieve a gain.
🏡🔖👣 Endowment Effect: We tend to overvalue things simply because we own them. For instance, we might ask for more money to sell our used car than what we would be willing to pay for the exact same car owned by someone else.
💤👥🎯 Cognitive Ease: When things are easy to think about or perceive, we tend to prefer them. For instance, stocks of companies with easy-to-pronounce names often do better than those with complex names, not because of their value, but because of cognitive ease.
