🤖 AI Summary
🏆 Daniel Kahneman’s Decision-Making Strategy: The Cheat Sheet
🧠 The Dual-System Framework (Core Philosophy)
- ⚡️ System 1: The “Fast” Thinker
- 🏃 Automatic & Effortless: Operates automatically, quickly, and with no sense of voluntary control.
- 🤩 Intuitive & Emotional: Source of impressions, intuitions, intentions, and feelings.
- 🌍 Constantly Active: Creates a coherent model of the world; the “hero” of mental life.
- 💥 Prone to Biases: Jumps to conclusions; has little knowledge of logic or statistics.
- 💡 Examples: Driving on an empty road, solving , sensing hostility.
- 🐢 System ⏳ System 2: The “Slow” Thinker
- 🤔 Effortful & Deliberate: Requires conscious attention and mental effort.
- ⚖️ Logical & Calculating: Deals with complex computations, reasoning, and analysis.
- 🛋️ The Lazy Controller: Monitors and controls System 1’s suggestions, but is often lazy.
- 🛑 Role of Self-Control: Overcomes System 1 impulses; maintains focus.
- 💡 Examples: Multiplying , parking in a tight space, comparing complex options.
🗂️ Major Heuristics and Biases (System 1’s Flaws)
- ⚓️ Anchoring Effect:
- 🔢 Initial piece of information (“the anchor”) heavily sways subsequent judgments, even if irrelevant.
- ➡️ Action: Consider a wide range of information, not just the first number presented.
- 📰 Availability Heuristic:
- 💡 Events easily recalled (vivid, recent, emotional) are judged as more probable or frequent.
- 📊 Action: Use actual statistics and base rates, not just ease of memory/news coverage.
- 📉 Loss Aversion & Prospect Theory:
- 😭 The pain of a loss is psychologically about twice as powerful as the pleasure of an equivalent gain.
- 🎲 People prefer sure gains and seek risk to avoid certain losses.
- 🖼️ Framing Effect:
- 🗣️ The way information is presented (e.g., “90% success” vs. “10% failure”) changes preference, even if objective facts are identical.
- 🔄 Action: Reframe choices in multiple ways (positive and negative) before deciding.
- 🙈 What You See Is All There Is (WYSIATI):
- 🧩 System 1 constructs a coherent story only from the information available, ignoring what it doesn’t know.
- 🧐 Leads to overconfidence and jumping to conclusions.
- 🔎 Action: Actively seek out missing or disconfirming information.
- ❓ SUBSTITUTION / Answering an Easier Question:
- 🛣️ When faced with a hard question (Target Question), System 1 answers an easier, related one (Heuristic Question), without noticing the switch.
- 💰 Example: Target: “Should I invest?” Heuristic: “Do I feel confident about this idea?”
🛠️ Actionable Steps for Better Decisions
- 📋 Use a Checklist/Process:
- 📈 For high-stakes decisions, force System 2 engagement.
- ✅ Use checklists before finalizing to ensure all dimensions are considered.
- 🔭 Seek an “Outside View”:
- 📊 Combat the planning fallacy and overconfidence by looking at outcomes for similar projects/people (reference class).
- 🚫 Ignore your unique, optimistic “Inside View.”
- 💀 Conduct a Pre-mortem:
- 🔮 Before a decision is final, imagine it has failed spectacularly one year from now.
- ✍️ Write a short history of that failure; this legitimizes doubts and uncovers hidden risks.
- 😈 Appoint a Devil’s Advocate:
- 💬 Formalize the role of someone challenging the dominant intuitive view.
- ⌚️ Engage System 2’s critical oversight before commitment.
- 💯 Anchor on Base Rates:
- 🔢 Always start your probability estimate with the relevant statistical base rate.
- 🤏 Adjust this anchor only slightly based on specific, high-quality evidence.
👤 The Two Selves
- 🎭 The Experiencing Self:
- 🎁 Lives in the moment; registers happiness and pain as it happens.
- ⏱️ The duration of an experience is important to this self.
- 📸 The Remembering Self:
- 💯 Keeps score; constructs the story of life; makes future decisions.
- 🏔️ Governed by the Peak-End Rule: memories are determined by the most intense moment (peak) and the end of the event.
- 🤔 The Remembering Self is often a poor guide for the Experiencing Self’s well-being.
- 🔑 Real Happiness: Focus should be on time spent in flow, with loved ones, and free of pain/stress (i.e., improving the Experiencing Self’s day-to-day quality).
