Secrets of happiness: the happiness hacks backed up by science

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 we can bring more happiness into our lives. In episode
two, Ian Sample asks which happiness strategies are backed up by
science. He hears from Elizabeth Dunn, a professor of psychology at
the University of British Columbia, who recently scrutinised a
whole lot of happiness research to work out which recommendations
are most reliable. Help support our independent journalism at
