What collective narcissism does to society

What collective narcissism does to society

Scott Barry Kaufman writes: In 2005, the psychologist Agnieszka Golec de Zavala was researching extremist groups, trying to understand what leads people to commit acts of terrorist violence. She began to notice something that looked a lot like what the 20th-century scholars Theodor Adorno and Erich Fromm had referred to as “group narcissism”: Golec de Zavala defined it to me as “a belief that the exaggerated greatness of one’s group is not sufficiently recognized by others,” in which that thirst…

People mistake the internet’s knowledge for their own

People mistake the internet’s knowledge for their own

John Timmer writes: Many of us make jokes about how we’ve outsourced part of our brain to electronic devices. But based on a new paper by the University of Texas at Austin’s Adrian Ward, this is just a variation on something that has been happening throughout human history. No person could ever learn everything they need to know. But that’s OK, according to Ward: “No one person needs to know everything—they simply need to know who knows it.” Over time,…

Primate memory

Tetsuro Matsuzawa writes: The most recent common ancestor of chimpanzees and humans lived between five and seven million years ago. This shared heritage became evident when sequencing revealed a 1.2% DNA difference between species. Chimpanzees have a living sister species, bonobos, that is equally closely related to humans. Both chimpanzees and bonobos are found only in Africa; this is also true of gorillas. Chimpanzees and humans shared a common ancestor with gorillas between eight and nine million years ago. Another…

What if emotions aren’t universal but specific to each culture?

What if emotions aren’t universal but specific to each culture?

Elitsa Dermendzhiyska writes: The first time I saw Pixar’s movie Inside Out (2015), I was too entranced by its craftsmanship to realise that there was something odd, almost eerie, about its human characters. I was charmed by little Riley, the protagonist, with the chattering critters prancing around in her head. There’s Joy, a feisty version of Tinker Bell with cropped blue hair and indomitable optimism; Anger, a flaming-red stump with eyes like slits and fire bursting from his head; Sadness,…

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…

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…
