Key Takeaways

  • Blind Analysis: Scientists prevent confirmation bias by hiding final results until all error-checking is complete. Teams agree on methodology first, then reveal data only after committing to accept whatever outcome appears, eliminating the tendency to scrutinize unexpected results more harshly than expected ones.
  • Individual Humility vs Collective Arrogance: Scientists spend 95% of time searching for mistakes in their own work, constantly questioning assumptions and theories. This doubt becomes a superpower when balanced with collective confidence that difficult problems can be solved if teams persist long enough beyond typical giving-up points.
  • Scenario Planning for Decisions: Identify multiple independent driving forces that could affect outcomes. Map extreme combinations of two factors creating four distinct futures. Analyze optimal strategies for each scenario to reveal robust decisions that work across multiple possible worlds, avoiding groupthink around single predicted futures.
  • Sequential Court Bias: Norwegian Supreme Court has lowest disagreement rates because the most senior judge speaks first, creating conformity pressure. Swedish courts have youngest members speak first, generating more productive disagreement. Speaking order dramatically impacts whether groups find errors in reasoning or simply confirm initial positions.
  • Team Information Gathering: Have team members write down independent assessments before any group discussion to avoid herd thinking. The first person speaking influences everyone else, causing people to withhold contradictory information or alternative perspectives to avoid appearing confrontational, losing valuable diverse input.

What It Covers

Nobel Prize physicist Saul Perlmutter discusses applying scientific thinking to everyday decisions, the power of productive disagreement, managing uncertainty through probabilistic thinking, and how his team discovered the universe's accelerating expansion through collaborative research.

Notable Moment

The team spent five years collecting zero usable supernova measurements despite expecting results in three years. They had to catch exploding stars during a brief two-week rise period, with each galaxy only producing one every few hundred years, requiring global coordination and backup systems.

Episode Transcript

Hi, everybody, and welcome to In Good Company. I'm Nicola Tangen, the CEO of the Norwegian Sewell and Wealth Fund. And today, I'm in particularly good company with Saul Perlmutter, who I would argue easily is the cleverest person we ever had on the podcast because Saul won the Nobel Prize in Physics for discovering that the universe expands at an increasingly rapid pace. Now, you've also written a book called Third Millennium Thinking, which teaches us how to use scientific method in order to navigate this increasingly uncertain world. So so, big welcome to to this podcast. Thank you. It's good to be here. I thought we could start with the book and kind of the scientific thinking. So what is Third Millennium Thinking? Well, it's a bit of a, of a odd name because what we really want to capture is the direction in which we think the best of our scientific style of thinking has been helping our whole society, be able to do better in working through problems together. And we want to try to capture what does that really look like so that people, can realize that there's so many elements of it that they could all be using in their daily life, and also that they could be using when they're talking to other people and working out problems together. Mhmm. And, in some sense, I'd say that we've learned by now how to solve really dramatic problems and and difficult problems and interesting problems in the world. The one that I feel is the leftover problem that we can make a huge difference if we can solve is just how to talk to each other, how to work problems out together so that we can actually use all these other techniques that we've learned. Because the first time I met you, when we when we spoke, you said, you know, Nikolai, we can now solve all the problems in the world. You know, climate, how to feed people, but we don't manage to because we don't talk to each other. I mean, it's remarkable. I think we actually live at an incredible moment in history and prehistory and, and in fact, you know, maybe even cosmic history, where we are the first generations on this planet, who have the ability to solve planetary sized problems. I think, you know, the idea that there could be a pandemic and we actually know what to do about a pandemic, we have billions of people living on the planet, many more than when we were children, and we, at the time when we were children, most of the world was going to bed hungry. Today that's a very small percentage and we now know how it's possible to feed a planet. We could even handle things like, you know, climate changes that have happened throughout history have wiped out civilizations at different points in different ways. Today, for the very first time ever, we know how …
