Episode Details

In 1902, chemist Harvey Wiley recruited healthy volunteers for the famous “Poison Squad,” testing the effects of food preservatives under controlled conditions. The experiments drew national attention and helped build support for stronger federal food-safety laws. Wiley understood something most people miss about persuasion: undeniable evidence changes minds faster than words. The same principle applies to confidence. Repeating affirmations cannot compete with the psychological impact of actually doing something difficult. In today’s episode, we break down why confidence is built through proof, not internal persuasion—and why one decisive action can change how you see your own capability.
