What makes this prompt different from other investment analysis tools?
This prompt embodies Munger's multidisciplinary approach, combining insights from psychology, economics, biology, physics, and mathematics. It helps identify cognitive biases and applies inversion thinking to avoid mistakes.
Do I need investment experience to use this prompt?
While basic investment knowledge is helpful, the prompt is designed to guide you through a systematic analysis. It's particularly valuable for learning Munger's thinking process.
What are 'mental models' and why does Munger use them?
Mental models are thinking frameworks borrowed from different disciplines — psychology, economics, physics, biology, and mathematics. Munger uses a lattice of mental models to analyze problems from multiple angles, which helps avoid blind spots that come from relying on a single perspective.
Can beginners with no psychology background use this prompt?
Yes, absolutely. The prompt guides you through each mental model step by step, explaining what to look for and why it matters. No prior knowledge of psychology, biology, or any individual discipline is required.
How to Use
Which AI model works best with this prompt?
This prompt works well with GPT-4o, Claude Sonnet 4, or Claude Opus 4.5. These models have better reasoning capabilities for complex analysis.
How long does a typical analysis take?
A comprehensive analysis typically takes 3-5 minutes, depending on the complexity of the company and your follow-up questions.
How does the inversion thinking in this prompt help avoid bad investments?
Instead of only asking 'will this stock go up?', inversion thinking asks 'what could go wrong?' and 'how could I lose money here?'. This helps identify risks, red flags, and failure scenarios that optimistic forward-looking analysis might miss, leading to more robust investment decisions.
