Human Element

Psychology and behaviour

Human Element covers the psychology of discovery. How astronauts hold up under pressure, why people believe what they believe, and what research on the human mind can and cannot tell us.

The Korean alphabet, called Hangul, is the only major writing system in human history with a known inventor and a documented design rationale — created in 1443 by King Sejong of the Joseon dynasty, who designed each consonant to physically represent the position of the tongue and lips during the corresponding sound, and published a companion document explaining exactly why each letter looked the way it did

Nobody knows who invented the letter A. Nobody knows who invented the letter B, or C, or any other letter of any writing system used by any other major language on Earth.

In 1953, South Korea had a per-capita income lower than that of Somalia or Haiti — and within roughly seventy years, it became the world’s tenth-largest economy and the dominant global producer of memory chips, in the fastest national economic transformation in modern history

The economic case for South Korea's hopelessness was, in 1953, structurally compelling.

For years, Nazi Germany had used the German boxer Max Schmeling as a public symbol of Aryan racial superiority over Black athletes — and the American Joe Louis’s defeat of Schmeling at Yankee Stadium on June 22, 1938, ended that argument, in front of 70,000 spectators and 100 million radio listeners worldwide, in 124 seconds

There was a moment, during the second round of a different fight in May 1981 in Las Vegas, when an old German man in his seventies sat in a hotel suite paying…

The “Happy Birthday” song, the most frequently sung piece of music on Earth, was originally written in 1893 by two American sisters as a kindergarten classroom greeting called “Good Morning to All” — and the birthday lyrics now sung at every party on the planet were added almost twenty years later by an unknown author

If two women in 19th-century Louisville had written essentially anything else — a nursery rhyme, a folk hymn, a marching band number, a parlour song — their…

Bubble wrap was originally invented in 1957 by an American mechanical engineer and a Swiss chemical engineer trying to design a textured plastic wallpaper for the Beat generation — failed, tried selling it as greenhouse insulation, failed again — and was saved only when IBM started using it to ship its 1401 mainframe computers

The original wallpaper concept was, by every available account from the period, a perfectly reasonable mid-century product idea.

The most widely consumed beverage on Earth outside of water and tea originally contained cocaine — formulated in 1886 by an American Civil War veteran named John Pemberton as a patent medicine to cure his own morphine addiction, because Pemberton genuinely believed he was selling a medical tonic, not the soft drink it eventually became

The 1886 American pharmaceutical landscape into which Coca-Cola was introduced bore essentially no resemblance to the regulated drug-approval system that has…

The Eiffel Tower, now the most photographed structure on Earth, was built in 1889 as a temporary centerpiece for the Paris World’s Fair — meant to be dismantled after 20 years — and was saved from demolition in 1909 only because Gustave Eiffel himself arranged for the French military to use its iron lattice as a radio antenna for transmitting wireless signals across long distances

The Eiffel Tower's existence, in its original 1880s context, was a deeply contested proposition.

The Hollywood sign was erected in 1923 as a temporary $21,000 advertisement for a hillside real estate development called Hollywoodland — meant to come down after 18 months, but the developers found it useful, the public grew attached, the city inherited it in 1944, and the most famous sign on the planet is technically the leftover billboard for a real estate project from a century ago

Almost every tourist who flies into Los Angeles, drives up Beachwood Canyon, points a phone at the white letters on the hillside, and posts the resulting…

Since the first Japanese bullet train left Tokyo Station on October 1, 1964 — just nine days before the opening of the Tokyo Olympics — the Shinkansen has carried more than 10 billion passengers across 60 years of continuous high-speed operation, and has never had a single passenger fatality caused by derailment or collision in its entire history

Every other country that has ever built a high-speed rail system has, sooner or later, killed people with it.

On 26 September 1991, eight people locked themselves inside a three-acre world of glass and steel in the Arizona desert — and two years later emerged gaunt, oxygen-deprived, and having discovered that the building’s own walls had been slowly stealing the air

On 26 September 1991, eight people entered Biosphere 2, a sealed glass and steel structure in Oracle, Arizona, built to test whether a human-made ecosystem could keep people alive for two years.

Human Behaviour

On May 11, 1997, the reigning world chess champion Garry Kasparov sat down in a Manhattan office tower to play the final game of his rematch against an IBM computer called Deep Blue — and resigned in under an hour, in what may be the cleanest moment in modern history when a domain of human cognition quietly crossed over to a machine

The boundary between what computers can do and what only humans can do has moved many times across the past 80 years, but it has rarely moved in a way that anyone could see happening in real time.

Psychology

Early emotional states become physically embedded in the architecture of the developing brain — and laughter, according to recent research, is one of the experiences doing that work

A new synthesis from early childhood neuroscience argues that shared laughter does specific, measurable work in the infant brain — though the full picture is more incremental than the headlines suggest.

Psychology

At twenty, the brain processes information faster than it ever will again. In middle age, the same brain may read other people’s emotions more accurately than it ever has. By the late sixties, its vocabulary can still be climbing. The human mind does not peak once — it rotates.

Hartshorne and Germine's 2015 Psychological Science paper suggests that cognitive abilities peak on different timetables, from speed in youth to vocabulary much later.

On 12 April 1961, a 27-year-old Russian fighter pilot named Yuri Gagarin became the first human being in history to leave the Earth — sealed inside a metal sphere just over two metres wide, with the spacecraft’s controls locked because nobody knew what the human brain would do in weightlessness, and instructions to open a sealed envelope only if he lost his mind during the 108 minutes he spent orbiting the planet alone

The space race that produced Vostok 1 had begun in earnest approximately three and a half years earlier, on 4 October 1957, when the Soviet Union launched the…

Human Behaviour

Most people don’t realize that men now entering their 70s are often being asked to discuss feelings they were raised to keep out of view

The men now turning seventy were trained inside an emotional grammar their grandsons would not recognize, and the cost of that training is only now coming due.

In the summer of 1858, a lesser-known 35-year-old naturalist named Alfred Russel Wallace mailed Charles Darwin a 20-page letter from the Indonesian jungle outlining the theory of evolution by natural selection — a theory Darwin had been quietly developing for 20 years without publishing — forcing Darwin to hastily share the credit with a man he had never met

The letter's author, Alfred Russel Wallace, was 35 years old, the seventh of nine children of a financially declining English family, largely self-educated…
