Thinking Clearly

A practical guide to testing your assumptions, avoiding cognitive traps, and making better decisions. No philosophy degree required-just honest self-examination.

Your brain is not a truth-seeking machine. It's a survival machine that happens to think. Understanding its shortcuts, biases, and blind spots is the first step to working around them.

What You'll Learn

  • How your brain deceives you - Common cognitive biases and why they exist
  • Testing assumptions - Applying scientific thinking to your own beliefs
  • Beyond either/or - Why most choices aren't binary
  • Emotional decision-making - Recognizing when feelings override reason
  • Changing your mind - The underrated skill of updating beliefs

Prerequisites

  • No prerequisites - everyone thinks
  • Willingness to question your own assumptions
  • Comfort with occasionally being wrong

Why This Matters

  • Every day you make decisions based on untested assumptions
  • Some assumptions are wrong and costing you opportunities
  • This isn't about being smarter - it's about being honest with yourself

A Note on Tone

This series isn't here to insult your intelligence. Everyone-including the person writing this-falls for these mental traps regularly. The goal isn't perfection. It's awareness. Once you can see the traps, you can sometimes avoid them. And "sometimes" is a massive improvement over "never."
