Like sharp kitchen knives, comparative reasoning is an extremely useful, but potentially dangerous tool. We all use comparative reasoning to generate new, interesting, creative ideas. Good comparisons help us understand things that are less familiar. This Deep Dive explains reasoning that uses comparisons, like metaphors, similes, and analogies. In addition to sparking new ideas, comparative reasoning can be powerfully persuasive. That makes knowing how to evaluate “This-is-Like-That” arguments extremely important.

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.
