Upgrade Yourself

Farnam Street (FS) is devoted to helping you develop an understanding of how the world really works, make better decisions, and live a better life. We address such topics as mental models, decision making, learning, reading, and the art of living.

In a world full of noise, Farnam Street is a place where you can step back and think about time-tested ideas while asking yourself questions that lead to meaningful understanding. We cover ideas from science and the humanities that will not only expand your intellectual horizons but also help you connect ideas, think in multidisciplinary ways, and explore meaning.

Headquartered in Ottawa, Canada, and run by Shane Parrish, we have helped millions of people master the best of what other people have already figured out.

The Great Mental Models: General Thinking Concepts

The old saying goes, “To the man with a hammer, everything looks like a nail.” But anyone who has done any kind of project knows a hammer often isn’t enough.
