643. Why Do Candles Still Exist?

In this episode of Freakonomics Radio, Stephen Dubner explores the enduring popularity of candles in a world dominated by electricity. He interviews Steve Horenziak, president of the National Candle Association and a research fellow at Procter & Gamble, about the history, uses, and surprising growth of the candle industry. The discussion covers the shift from candles as a necessity to a decorative and mood-setting item, the science of scent, and safety concerns. Dubner also speaks with anthropologist Gokcha Gunan about why people still cling to older technologies like candles, even in the face of modern alternatives, touching on concepts like "hygge," planned obsolescence, and the emotional connections we form with objects. The episode further explores listener's attachments to obsolete technologies and the psychological reasons behind keeping them.
