You’re constantly presented with competing data, strong opinions, and limited time to sort through them. One source points one way, another contradicts it, and colleagues bring arguments of their own. The HBR Guide to Critical Thinking Toolkit helps you cut through that complexity with exercises and worksheets that clarify the problem. These resources guide you to test assumptions, recognize blind spots, and weigh alternatives in a more deliberate way, putting critical thinking at the center of how you lead.
