Mental Model Decision Journal

Don't rely on intuition alone. Apply proven frameworks like Inversion and Second-Order Thinking to solve complex problems.

Why Your Brain Needs a Journal

Our brains are wired for efficiency, often relying on "heuristics" (shortcuts) that lead to cognitive biases. When you keep thoughts in your head, they remain abstract and emotional.

Decision Journaling is the process of "Cognitive Offloading." By writing your logic down, you separate the quality of the decision from the outcome.

This tool forces you to slow down and view problems through structured Mental Models—proven frameworks used by billionaires and chess grandmasters to minimize error.

The "Resulting" Fallacy

In poker, players call it "Resulting"—judging a decision only by its outcome.

Scenario: You drive drunk and get home safely.
The Result: Good (Safety).
The Decision: Terrible.

A journal helps you spot "lucky" bad decisions before your luck runs out.

The Frameworks Explained

Inversion

Instead of asking "How do I succeed?", ask "How could I fail?". Identify the failure points and avoid them.

Second-Order

First-order thinking is immediate ("Eat donut"). Second-order looks at the future ("Eat donut -> Sugar crash -> Lost focus").

Regret Min.

Project yourself to age 80. Will you regret trying and failing, or will you regret not trying at all?

Check Yourself for Biases

Before you click "Save Entry," check if any of these common psychological traps are influencing your logic.

  • Confirmation Bias: Seeking only info that supports your existing belief. Fix: Actively search for one reason you might be wrong.
  • Sunk Cost Fallacy: Continuing because you've already invested time/money. Fix: Ask "If I started today with zero investment, would I do this?"
  • Recency Bias: Overweighting recent events. Fix: Zoom out and look at long-term historical averages.
