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.

Mind & Meaning

In 1610, the Italian astronomer Galileo Galilei pointed a small telescope at Jupiter and saw four small objects circling it — becoming the first human being in history to look at the night sky and see, with his own eyes, that the Earth was not the center of everything

On the first night, 7 January 1610, Galileo recorded what he was seeing in his observation notebook with the careful, slightly bemused understatement of a researcher who knew he was looking at something interesting but did not yet know what.

Psychology

Stanford psychologist Laura Carstensen found that when older adults were asked to imagine a medical breakthrough adding decades to their lives, their preferences shifted back toward those of younger people — suggesting that the emotional calm of old age may come less from age itself than from the way a shrinking time horizon changes what people value.

Carstensen's socioemotional selectivity theory suggests that perceived future time, not age alone, helps shape social preferences and emotional priorities in later life.

Human Behaviour

The hundreds of human skeletons scattered around Roopkund Lake at 5,029 metres in the Indian Himalayas were long assumed to be the remains of a single 9th-century pilgrimage group killed by a sudden hailstorm, in an explanation that a 2019 peer-reviewed ancient DNA study has substantially overturned, by demonstrating that the skeletons came from at least three different populations and died across more than one thousand years.

Roopkund Lake sits at 5,029 metres above sea level in the Chamoli District of Uttarakhand, India, between the peaks of Trishul and Nanda Ghunti.

Mind & Meaning

When archaeologists excavating a Han Dynasty tomb near Changsha in 1971 opened the innermost of four nested coffins, they found the body of a noblewoman named Xin Zhui — who had died roughly 2,140 years ago — so perfectly preserved that her skin was still soft, her joints still moved, and her stomach still contained 138 melon seeds from her last meal, making it the best-preserved human body ever recovered from the ancient world

The Chinese hospital workers digging an air raid shelter in 1971 expected to find rock, soil, and possibly some inconveniently large tree roots.

Human Behaviour

In 1975, the developmental psychologist Edward Tronick filmed mothers dropping their faces into a blank mask and found that even securely attached pairs fall out of sync roughly seventy percent of the time, and that what holds the bond together is not the match but the repair that follows the rupture

Edward Tronick's still-face research found that even securely attached mother-infant pairs are out of emotional sync most of the time — and that what predicts secure attachment is not the frequency of attuned moments, but the reliability of repair after rupture.
