The latest volume in the bestselling series from Edge.org—dubbed “the world’s smartest website” by The Guardian—brings together 206 of the world’s most innovative thinkers to discuss the scientific concepts that everyone should know.
As science informs public policy, decision making, and so many aspects of our everyday lives, a scientifically literate society is crucial. In that spirit, Edge.org publisher and author of Know This, John Brockman, asks 206 of the world’s most brilliant minds the 2017 Edge Question: What scientific term or concept ought to be more widely known?
Contributors include: author of The God Delusion RICHARD DAWKINS on using animals’ “Genetic Book of the Dead” to reconstruct ecological history; MacArthur Fellow REBECCA NEWBERGER GOLDSTEIN on “scientific realism,” the idea that scientific theories explain phenomena beyond what we can see and touch; author of Seven Brief Lessons on Physics CARLO ROVELLI on “relative information,” which governs the physical world around us; theoretical physicist LAWRENCE M. KRAUSS on the hidden blessings of “uncertainty”; cognitive scientist and author of The Language Instinct STEVEN PINKER on “The Second Law of Thermodynamics”; biogerontologist AUBREY DE GREY on why “maladaptive traits” have been conserved evolutionarily; musician BRIAN ENO on “confirmation bias” in the internet age; Man Booker-winning author of Atonement IAN MCEWAN on the “Navier-Stokes Equations,” which govern everything from weather prediction to aircraft design and blood flow; plus pieces from RICHARD THALER, JARED DIAMOND, NICHOLAS CARR, JANNA LEVIN, LISA RANDALL, KEVIN KELLY, DANIEL COLEMAN, FRANK WILCZEK, RORY SUTHERLAND, NINA JABLONSKI, MARTIN REES, ALISON GOPNIK, and many, many others.

"To alloparent is to provide care for offspring that aren’t your own. It’s an unimaginable behavior for most species (few of which even care for their own offspring); rare even among relatively nurturant classes of animals, like birds and mammals; but central to the existence of humankind. The vigor and promiscuity with which humans in every culture around the world alloparent stands in stark contrast to widespread misconceptions about who we are and how we should raise our children."
"Imagine trying to figure out the average family size in a particular neighborhood. You could ask the parents how many kids they have. Big families and small families will count equally. Or you could ask the children how many siblings they have. A family with five kids will show up in the data five times, and childless families won’t show up at all. The question is the same: “How big is your family?” But when you ask kids instead of parents, the answers are weighted by the size of the family. This isn’t a data error so much as a trick of reality: The average kid actually has a bigger family than the average parent does."
"Snapshots bias samples: When some people experience something—like a prison release—more often than others, looking at a random moment in time guarantees a non-random assortment of people."
"To be correct, an answer needs to be about the same population as the question it answers. But length-biased sampling also explains how our social positions can give us very different experiences of the world—as when, if a small group of men each harasses many women, few men know a harasser but many women are harassed."
"Suppose that two people witness a crime: One describes in words what she saw, while the other doesn’t. When tested later on their memories of the event, the person who verbally described the incident will be worse at remembering or recognizing what actually happened. This is verbal overshadowing."
"[R]ecent research in neuroscience, ecology, and psychology shows that phenotypic plasticity extends to behaviors. For instance, in a harsh and unpredictable environment where the future is dreary, organisms tend to adopt a short-term life strategy, maturing and reproducing earlier, investing less in offspring and pair-bonding, being more impulsive. In a more favorable and predictable environment, organisms switch to a long-term strategy, maturing and reproducing later, investing in offspring and pair-bonding, and being more patient."
"The future belongs to those brave enough to be humble about how little we know and how much is remaining to be discovered."
