What is Decision Making?
Let's define decision making. Decision making is just what it sounds like: the action or process of making decisions. Sometimes we make logical decisions, but there are many times when we make emotional, irrational, and confusing choices. This page covers why we make poor decisions and discusses useful frameworks to expand your decision-making toolbox.
Why We Make Poor Decisions
I like to think of myself as a rational person, but I’m not one. The good news is it’s not just me — or you. We are all irrational. For a long time, researchers and economists believed that humans made logical, well-considered decisions. In recent decades, however, researchers have uncovered a wide range of mental errors that derail our thinking. The articles below outline where we often go wrong and what to do about it.

- Two Harvard Professors Reveal One Reason Our Brains Love to Procrastinate: We have a tendency to care too much about our present selves and not enough about our future selves. If you want to beat procrastination and make better long-term choices, then you have to find a way to make your present self act in the best interest of your future self. This article breaks down three simple ways to do just that.
How to Use Mental Models for Smart Decision Making
The smartest way to improve your decision making skills is to learn mental models. A mental model is a framework or theory that helps to explain why the world works the way it does. Each mental model is a concept that helps us make sense of the world and offers a way of looking at the problems of life.
