Self-help ✦ Penny’s Take

How Confidence Works

Ian Robertson · 2021
83/100
👍 Worth It

Ian Robertson is the real deal — Co-Director of the Global Brain Health Institute — and this book brings actual neuroscience to a genre that is usually light on evidence. The writing is accessible without being dumbed down, and the societal and political scale of his confidence argument makes it more interesting than a standard self-help read. Readers who want a prescription-heavy workbook may feel underserved, but anyone who wants to understand the science behind self-belief will come away with a lot.
