Elon Musk is on record that he makes decisions using the same technique as Jeff Bezos.
I found YouTube videos of them explaining it.
A thread on thinking more clearly:
This thread is about mental models.
Yes, Twitter has enough of these.
BUT, people never answer the question:
How do I use mental models for everyday decisions? How do I put them into practice?
Mental models are frameworks for thinking.
They simplify complex situations so you can reason through them easily.
They help you make good, long-term decisions without needing to know everything about a situation.
Your hunter-gatherer brain is not wired to use the best model for every decision.
However, in every generation, a few humans manage to rewire their biology:
They force themselves to think in models constantly.
Elon Musk and Jeff Bezos appear to be two of those people. They're on record about this.
