THE
LATTICEWORK

Welcome to the Latticework

This is a compendium of laws, rules, models, theories, heuristics, and observations about the world around us. We have compiled this latticework to help with general thinking concepts and decision making.

While this is an overview of many useful things to know, it is merely that: an overview. Over time, we will build this out to make it more robust and full.

Mental models are a framework of tools to help you think better. Learning to adeptly implement mental models into your everyday thinking will help you avoid the pitfalls of life.

Sticking to that which we understand and avoiding decisions outside of our expertise.

The first basis from which a thing is known, a basic assumption or idea that cannot be deduced any further.

Incentives influence outcomes. Show me the incentive, I’ll show you the outcome.

One should not attribute to malice that which is more easily explained by stupidity or ignorance.

The practice of turning a problem upside down and starting from another point. Invert, always invert.

Simple explanations are more likely to be correct than complicated ones.

Premortem

A type of thought experiment where you imagine an endeavor has failed and you then try to determine what could lead to that failure.

Postmortem

Biases affect how you interpret and process information. Biases are generally accepted to be impossible to eliminate; however, they can be mitigated. Biases are much easier spotted in other people than in ourselves, so it is important to have advisors and confidants to help you identify biases in your thinking.
