To optimize decision-making we must understand how we make decisions. Human choices are neither programmed nor random. But they are reactive and reflective. These two powerful forces within us can cooperate or compete. Our decision-making is layered upon millennia of evolutionary learning. That learning scripted our species with reactive decision-making shortcuts. Called “cognitive heuristics,” they are often valuable. But over-relying on them is risky.

There are two parts to our Deep Dive into human decision-making. Part 1 describes our natural reactive and reflective decision-making engines. And it begins the countdown of the Top-12 heuristic shortcuts. We look at their advantages and their risks. And we explore strategies to overcome those risks. Part 2 completes the countdown. And there we describe how we build up the confidence to act on the choices we make. Learn all the ways to optimize decision-making by completing both parts.

Deep Dives are short courses that focus on a specific aspect of human problem-solving and decision-making. Each Deep Dive includes real-world examples, detailed clarifications of key concepts. Questions and their answers reinforce central ideas. Reflective exercises deepen understanding of how you can apply lessons learned to your life and work.

When you complete a Deep Dive, you will see your Results Report. It includes detailed on-screen personal feedback and a summary of key ideas you can download.
