Lockdowns may have eroded people’s swagger, but research suggests there are ways to remedy the situation

In July 2007, the Irish golfer Padraig Harrington won one of golf’s most coveted competitions, the British Open. The story of how he did this, one of the most remarkable finishes in golfing history, illustrates one of the ways confidence works.

The Claret Jug – the Open’s famous prize – was within Harrington’s grasp as he teed off at the penultimate hole of the tournament. He had a one-shot lead on his arch-rival, Sergio García. He was entirely in the zone – “I am literally the most confident person at that point in time,” he said later. Then, something strange happened – a twinge of doubt came out of nowhere at the top of his back swing and he sliced the ball into the murky waters of the notorious Barry Burn river.
