How Confidence Works

Ian Robertson · 2021
🎙 Narrated by Ian Robertson
79/100
👍 Worth It

Robertson's central move — framing confidence as a systemic social force rather than a personal trait — is substantive and better-grounded than the typical self-help confidence book, backed by endorsements from Steven Pinker, Johann Hari, and coverage in Nature. The breadth from neuroscience to politics is genuinely ambitious but will feel unfocused to anyone who came for personal-development tools rather than intellectual scope. Robertson narrates his own material and that Irish academic clarity is an asset for dense science, not a liability.

🎙 Narration: good Robertson's own delivery is clear and authoritative — the Irish academic register suits the material, and self-narration benefits the science-heavy passages.
