This Challenge asks you to tell us a story about a decision: a decision that changed the course of humanity, in a small or large way. Identify a historical figure in whom you are interested (or are studying). Then select one key decision that figure made; a decision that had impact and consequences, both personally and societally. And tell us the story of that decision. To help you tell that story, we are employing a decision-making rubric from a team of Decision Scientists that will help with both understanding the science of decision-making, as well as assist with good storytelling!
