ALL PRETTY MODELS ARE WRONG, BUT SOME UGLY MODELS ARE USEFUL

Summary from the TLDR Founders newsletter

Models can be useful even when they're wrong about how the world works—ancient Mayans predicted eclipses with remarkable accuracy despite their laughable cosmology. Similarly, our business frameworks should be judged on usefulness, not attractiveness. Be suspicious of conveniently symmetrical models with exactly four quadrants, ten bullet points, or perfectly balanced categories—humans, companies, and markets are messy and asymmetrical. Good frameworks embrace this complexity rather than forcing reality into neat diagrams that look good in PowerPoint.
