There's a strange leadership trap that the Stoics noticed but never quite named — and that Kahneman's research on 'System 1 thinking' accidentally illuminates perfectly. When you're in a position of authority, people stop disagreeing with you out loud. They don't stop disagreeing. They just go quiet. What you experience as consensus is often just the social cost of contradiction. Seneca, in his Letters to Lucilius, warned that the powerful man is surrounded by flatterers who 'tell him what pleases rather than what profits' — and Kahneman's work on cognitive ease shows why this feels so good: agreement is literally processed faster and more pleasurably by the brain than challenge. The practical move is almost embarrassingly simple, but most leaders never do it: ask not 'does anyone disagree?' but 'what's the strongest case against this decision?' One invites silence. The other makes dissent a contribution.

When was the last time someone close to you — a colleague, a friend, a partner — genuinely changed your mind, and what made it possible for them to say the thing that did it?
