Instead of analysing actions, checking through the consequences of those actions and chatting through the decisions made, leaders too often rely on impulsive decision-making - and this is when hubris can set in.

“None of these systems is infallible. You need a jazz quartet of them to achieve full human intelligence,” Prof Claxton says.

“Traditionally, powerful people had a joker following them around, making jokes and poking fun at them, reminding them that they are just human beings.”

This suggests that a reminder of your own fallibility is necessary when you are a leader in any field.

Another danger for powerful people is a potential lack of empathy for others, a subject also discussed at the Royal Society of Medicine conference.
