This is a Mental Models that asks: What is the most efficient way to solve a problem if you started from scratch? If you look past humanity’s attempts to solve it, what is the best approach if you reasoned from its fundamental principles.
This is extremely important if you want to have impact in any sort of way as a startup founder (How to Get Startup Ideas), blogger, researcher, or general knowledge worker (because Contrarian Thinking is a major role in most ppl’s success).
