AI is no match for the quirks of human intelligence

AI is no match for the quirks of human intelligence

Herbert Roitblat writes: At least since the 1950s, the idea that it would be possible to soon create a machine that was capable of matching the full scope and level of achievement of human intelligence has been greeted with equal amounts of hype and hysteria. We’ve now succeeded in creating machines that can solve specific fairly narrow problems — “smart” machines that can diagnose disease, drive cars, understand speech, and beat us at chess — but general intelligence remains elusive….

Sunlight affects whether languages have a word for ‘blue’

Sunlight affects whether languages have a word for ‘blue’

Cathleen O’Grady writes: Color is a spectrum: Red fades from orange to yellow, whereas green merges to turquoise, then blue. Languages treat this spectrum in different ways: Some have separate words for “green” and “blue,” others lump the two together. Some barely bother with color terms at all. “The question is, why?” says Dan Dediu, an evolutionary linguist at Lumière University Lyon 2. Now, he and his colleagues have found evidence for an unexpected answer: People with more exposure to…

How memories persist where bodies and even brains do not

How memories persist where bodies and even brains do not

Thomas R Verny writes: I began exploring the concept of cellular memory – the idea that memory can be stored outside the brain, in all the body’s cells – after reading an article on Reuters headlined ‘Tiny Brain No Obstacle to French Civil Servant’ in 2007. It seems that a 44-year-old French man had gone to hospital complaining of a mild weakness in his left leg. Doctors learned that the patient ‘had a shunt inserted into his head to drain…

Can progressives be persuaded that genetics matters?

Can progressives be persuaded that genetics matters?

Gideon Lewis-Kraus writes: [Kathryn Paige] Harden understands herself to be waging a two-front campaign. On her left are those inclined to insist that genes don’t really matter; on her right are those who suspect that genes are, in fact, the only things that matter. The history of behavior genetics is the story of each generation’s attempt to chart a middle course. When the discipline first began to coalesce, in the early nineteen-sixties, the memory of Nazi atrocities rendered the eugenics…

Why walking helps us think

Why walking helps us think

Ferris Jabr writes: In Vogue’s 1969 Christmas issue, Vladimir Nabokov offered some advice for teaching James Joyce’s “Ulysses”: “Instead of perpetuating the pretentious nonsense of Homeric, chromatic, and visceral chapter headings, instructors should prepare maps of Dublin with Bloom’s and Stephen’s intertwining itineraries clearly traced.” He drew a charming one himself. Several decades later, a Boston College English professor named Joseph Nugent and his colleagues put together an annotated Google map that shadows Stephen Dedalus and Leopold Bloom step by…

The social and environmental perils of magical thinking

The social and environmental perils of magical thinking

By Louise Fabiani There has been much coverage in recent media of citizens who fail to acknowledge the existence of such global crises as Covid-19 or anthropogenic climate change. They are said to be skeptical or in denial. They refuse to participate in any solution for the simple reason that they believe them to be non-issues. Just as dangerous to the common good is a person who fully accepts the existence of a problem, yet believes as a matter of…

The self is not singular but a fluid network of identities

The self is not singular but a fluid network of identities

Kathleen Wallace writes: Who am I? We all ask ourselves this question, and many like it. Is my identity determined by my DNA or am I product of how I’m raised? Can I change, and if so, how much? Is my identity just one thing, or can I have more than one? Since its beginning, philosophy has grappled with these questions, which are important to how we make choices and how we interact with the world around us. Socrates thought…

Do wild animals get PTSD? Scientists probe its evolutionary roots

Do wild animals get PTSD? Scientists probe its evolutionary roots

By Sharon Levy, Knowable Magazine Every few years, snowshoe hare numbers in the Canadian Yukon climb to a peak. As hare populations increase, so do those of their predators: lynx and coyotes. Then the hare population plummets and predators start to die off. The cycle is a famous phenomenon among ecologists and has been studied since the 1920s. In recent years, though, researchers have come to a startling conclusion: Hare numbers fall from their peak not just because predators eat…

There’s no emotion we ought to think harder about than anger

There’s no emotion we ought to think harder about than anger

Martha C Nussbaum writes: There’s no emotion we ought to think harder and more clearly about than anger. Anger greets most of us every day – in our personal relationships, in the workplace, on the highway, on airline trips – and, often, in our political lives as well. Anger is both poisonous and popular. Even when people acknowledge its destructive tendencies, they still so often cling to it, seeing it as a strong emotion, connected to self-respect and manliness (or,…

We’re learning the wrong lessons from the world’s happiest countries

We’re learning the wrong lessons from the world’s happiest countries

Joe Pinsker writes: Since 2012, most of the humans on Earth have been given a nearly annual reminder that there are entire nations of people who are measurably happier than they are. This uplifting yearly notification is known as the World Happiness Report. With the release of each report, which is published by the United Nations Sustainable Development Solutions Network, the question is not which country will appear at the top of the rankings, but rather which Northern European country…

Einstein thought imagination was crucial. Robert and Talbot Trudeau/Flickr, CC BY-NC By Barbara Jacquelyn Sahakian, University of Cambridge; Christelle Langley, University of Cambridge, and Victoria Leong, University of Cambridge IQ is often hailed as a crucial driver of success, particularly in fields such as science, innovation and technology. In fact, many people have an endless fascination with the IQ scores of famous people. But the truth is that some of the greatest achievements by our species have primarily relied on…

On dream sharing and its purpose

On dream sharing and its purpose

Matthew Spellberg writes: Among certain philosophers it is a commonplace that dreams are radically private, that no one can follow you into them. A fragment from Heraclitus distills the problem: “The universe for those who are awake is single and common, while in sleep each person turns aside into a private universe.” Hegel, commenting on this same fragment, says that “the dream is a knowledge of something of which I alone know.” Consider how you might teach a child to…

William James: Free will requires that we be able to exorcise habits

William James: Free will requires that we be able to exorcise habits

Gordon Marino writes: William James (1842–1910) is arguably one of the most brilliant and fecund minds this nation has ever produced. James and his friend Charles Sanders Peirce were the progenitors of the only distinctly American philosophical movement, pragmatism. The Principles of Psychology, published in 1890, marked James as the first prominent American psychologist. His The Varieties of Religious Experience (1902) established him as a pioneer in the study of comparative religion. Americans have long looked to Europe for intellectual…

Social media and the neuroscience of predictive processing

Social media and the neuroscience of predictive processing

Mark Miller and Ben White write: Levi Jed Murphy smoulders into the camera. It’s a powerful look: piercing blue eyes, high cheekbones, full lips and a razor-sharp jawline – all of which, he says, cost him around £30,000. Murphy is an influencer from Manchester in the UK, with a large social media following. Speaking on his approach to growing his fans, he says that, if a picture doesn’t receive a certain number of ‘Likes’ within a set time, it gets…

The age of misinformation in which ‘belonging is stronger than facts’

The age of misinformation in which ‘belonging is stronger than facts’

Max Fisher writes: There’s a decent chance you’ve had at least one of these rumors, all false, relayed to you as fact recently: that President Biden plans to force Americans to eat less meat; that Virginia is eliminating advanced math in schools to advance racial equality; and that border officials are mass-purchasing copies of Vice President Kamala Harris’s book to hand out to refugee children. All were amplified by partisan actors. But you’re just as likely, if not more so,…
