In Changing Minds: The Art and Science of Changing Our Own and Other People's Minds, Howard Gardner, a psychologist and professor at Harvard University, examines the factors involved in changing minds on significant issues, whether looking at politics, art or business. He identifies seven key elements, including reason, research and real world events, that are part of the decision-making process, noting that certain of these are weighted more heavily in decision making in some fields than in others. Gardner does also offer some suggestions for how someone can influence others, but he does not include a detailed strategy for decision makers in the business world, leaving readers to draw out insights on their own, but providing a solid starting point.
