Early detection of cancer seems like a very good idea. But it's a lot more complicated than it seems. Oncologist and epidemiologist Vinay Prasad of the University of California, San Francisco talks to EconTalk's Russ Roberts about why many tests to detect cancer do little or nothing to extend lifespan.

The favorite EconTalk episodes for host Russ Roberts are when he and his guest have an unusually powerful connection such as his recent episode with Charles Duhigg, and the ones where he learns something mind-blowing, like Adam Mastroianni’s insight that you can’t reach the brain through the ears. Listen as Russ explains how he chooses guests, and why EconTalk has evolved to focus on things other than economics. He also shares listeners' favorite conversations from 2023, and tells a story that shows the challenges—and opportunities—of applying EconTalk’s lessons to our personal lives.

The Top EconTalk Conversations of 2023 (with Russ Roberts)

Would an AI simulation of your dead loved one be a blessing or an abomination? And if you knew that after your own death, your loved ones would create a simulation of you, how would that knowledge change the way you choose to live today? These are some of the questions psychologist Paul Bloom discusses with EconTalk's Russ Roberts as we stand on the threshold of digital immortality.

Seeking Immortality (with Paul Bloom)

If the Wright Brothers could have used AI to guide their decision making, it's almost certain they would never have gotten off the ground. That's because, points out Teppo Felin of Utah State University and Oxford, all the evidence said human flight was impossible. So how and why did the Wrights persevere? Felin explains that the human ability to ignore existing data and evidence is not only our Achilles heel, but also one of our superpowers. Topics include the problems inherent in modeling our brains after computers, and the value of not only data-driven prediction, but also belief-driven experimentation.

When Prediction Is Not Enough (with Teppo Felin)

While religion may play less of a role in many people's lives, rituals--the lifeblood of religion--remain central to the human experience. Listen as Michael Norton of the Harvard Business School explains how and why rituals remain at the center of our lives--they give meaning to life-cycle events and secular holidays, calm our fears, and give us a sense of control when the pressure to perform can otherwise overwhelm us.

Rituals Without Religion (with Michael Norton)

Can you be too happy? Psychologist Adam Mastroianni talks with EconTalk's Russ Roberts about our emotional control systems, which seem to work at bringing both sadness and happiness back to a steady baseline. Too much happiness is--perhaps surprisingly--not necessarily a good thing. They also explore whether our general level of happiness is really related to events in our lives or connected to something much larger than ourselves.
