Help improve the book, workbook, and companion site

Reader feedback helps us improve The Defensible Decision, its Practice Workbook, and the companion site. We use it to identify corrections, clarify difficult material, improve exercises and visualizations, and prioritize future updates.

Please do not include sensitive or confidential information. Only provide an email address if you are comfortable being contacted. The form takes about two minutes.
