It is a good morning exercise for a research scientist to discard a pet hypothesis every day before breakfast. It keeps him young.

Insight: The real trap isn't believing something wrong—it's getting too comfortable with any single belief. Konrad Lorenz was pointing at something we all do: we build little theories about how things work, and then we protect them. A person decides their partner is "emotionally distant," so they interpret every quiet moment as confirmation. A manager assumes a quiet team member isn't engaged, and stops looking for evidence otherwise. We're not being dishonest; we're just being human. Once we've invested in an idea, it becomes easier to defend than to question. What's clever about Lorenz's image—doing this "before breakfast," like brushing your teeth—is that he's treating skepticism as a habit, not an occasional dramatic event. It's not about dismantling your entire worldview. It's about the daily practice of asking: what am I assuming today that I haven't actually checked lately? What story am I telling myself that's a little too neat? The surprising part is that this makes you younger, not more tired or uncertain. Staying rigid, always defending the same positions, is what ages you. When you can actually change your mind about something before lunch, you stay flexible, curious, and genuinely alive to what's actually happening around you.
