Science Talk

On this show, we’ve been talking about uncertainty from a variety of different angles. We’ve heard how uncertainty can be a spark for creativity and scientific discovery. We’ve discussed how uncertainty can go unseen and make science really difficult. And we’ve explored some of the research techniques and habits of mind that researchers use to deal with uncertainty. Today we’re going to end with two final questions: If science is always uncertain, how can we ever know anything? How can we have confidence in science if there’s always underlying uncertainty?

Science is an iterative process. Progress comes from people coming up with ideas that are sort of right and then new evidence and ideas coming in to update them to become even more correct. Underlying this process is a willingness by scientists to accept that they might be wrong and be open to updating their ideas. It turns out that social scientists have a term for this mindset. To find out more, I talked with two researchers who are studying this thing they call “intellectual humility.” Learn more about your ad choices. Visit megaphone.fm/adchoices

Today’s episode of Uncertain is about the ways that studies can leave us overconfident and how “just-so stories” can make us feel overly certain about results that are still a work in progress. And sometimes studies get misleading results because of random error or weird samples or study design. But sometimes science gets things wrong because it’s done by humans, and humans are fallible and imperfect.

In this episode, we’ll talk with two researchers whose work probes the uncertainty surrounding how we perceive the world around us.  It turns out that what we see may not always be a perfect reflection of reality.  Learn more about your ad choices. Visit megaphone.fm/adchoices

Welcome to Uncertain, a five-part podcast miniseries from Scientific American. Here we will dive head first into the possibilities of the unknowing. Over the next five episodes, I’ll be talking with people like her: explorers who work in the realm of uncertainty. Through them, we’ll discover the ways that uncertainty can spark curiosity and scientific breakthroughs. But we’ll also find out how uncertainty can bite us in the butt and make science really hard. We’ll see how neglecting uncertainty can lead to overconfidence and how embracing uncertainty can allow for a more nuanced and accurate understanding of the world. We’ll finish by examining how it’s possible to have confidence in scientific findings, even with their uncertainties. Learn more about your ad choices. Visit megaphone.fm/adchoices

Does the word "uncertainty" make you nervous? Does it rule your life? Would you say it kinda describes the state of the world these days?  Enter Uncertain, a new limited podcast series from Scientific American. In this series, host Christie Aschwanden will help to demystify uncertainty. She's going to take away its scariness–or, rather, a cast of scientific dreamers that she talked to, will.  As you’ll see, uncertainty drives scientific discovery. Throughout scientific history, uncertainty has spurred our collective imagination and our need to know the things we don’t.  To be clear, uncertainty makes science very difficult. So in this mini-series we’ll both learn how scientists push through those difficulties; and how they also avoid the bias, logical fallacies, and blindspots that can lurk behind uncertainty. She'll get them to share their own habits of mind and techniques for facing, and embracing, the unknown.  And even if you’re not a scientist, UNCERTAIN provides a practical way to think through what we don’t know in our lives—to face that uncertainty, and, hopefully, live better, more informed lives because of it.

It is a tale of sound: the song of a solitary whale that vocalizes at a unique frequency of 52 hertz, which no other whale—as the story goes—can seemingly understand. It is also a tale about science and ocean life, laced with fantasy and mystery and mostly shrouded in darkness. The whale, who is of unknown species and nicknamed “52,” was originally discovered in 1989 and has been intermittently tracked by scientists ever since. Its solitary nature baffled marine researchers. And its very existence captured the attention and hearts of millions of people. But as 52 roams the ocean’s depths, a lot about its nature is still up in the air. No one has ever seen it in the flesh. Scientists have determined that the whale is a large male and possibly a hybrid, and they have speculated that its unique song—too low in frequency for humans and too high for whales—might be a result of a malformation. Scientific American sat down with Josh Zeman, an award-winning filmmaker who created a documentary about 52, to talk not just about his impressive cinematic quest (and it is impressive and beautifully shot) but also the science and academic collaborations that fueled it. The documentary—written and directed by Zeman and executive produced by actors Leonardo DiCaprio and Adrian Grenier—is inspired by the findings of the late bioacoustics scientist William Watkins. It is propelled by passion and curiosity and relies on underwater acoustics to track 52 through the sound-rich and noise-heavy environment of the ocean. A departure for Zeman in terms of genre choice, the film still exudes an air of mystery and sleuthing reminiscent of whodunits. It unfolds like a classic true-crime story, a genre that Zeman, an investigative reporter and a true-crime documentarian, was originally famous for working in. Then again, when Zeman started making the movie, the whale was MIA and had been silent for years. In essence, Zeman reopened a cold case to—in his own words—“set the record straight” and “bring the audience into the world of the whale.” With the help of marine scientists, he followed streams of whale songs and other breadcrumbs in the form of auditory clues, listening in, analyzing, tracking, slowly and persistently narrowing down the circle around 52. Zeman found him, lost him and found him again until eventually the filmmaker made an unexpected revelation about him. It may not be the closure Zeman expected to give to his audiences. But it is definitely a fresh chapter in this evolving tale. Zeman says he is hopeful that other storytellers will take up the mantle and continue to unearth more facts about 52. “What a more beautiful gift can you give than to say, ‘Actually, there’s another chapter.’ And then, 20 years later, somebody else comes in and adds their chapter,” he says. “That’s what storytelling is.” Learn more about your ad choices.
