Richard P. Feynman, the late theoretical physicist, spoke about being fooled by numbers. He famously said: “The first principle is that you must not fool yourself and you are the easiest person to fool.” Numbers can also be scary. Many people avoid discussing numbers, which calls to mind a quotation from Mark Twain: “It is better to keep your mouth closed and to let people think you are a fool than to open it and remove all doubt.”

On this thread I want you to discuss two things: 1) Times when you made mistakes with numbers, and 2) Times when numbers scared you (Please, ignore Twain’s advice).
