Secrets of happiness: what makes a country happy?

At a moment when the world feels like a particularly unsettling
place, Science Weekly is asking what it is that makes humans happy
– and how can we bring more happiness into our lives? In episode
one, Ian Sample asks what makes a country happy? Johannes
Eichstaedt, assistant professor of psychology and human-centred AI
at Stanford University, explains why the Nordic countries often
rank highly in the annual World Happiness Report, and what we can
learn if we look beyond them. Help support our independent
