Margaret Heffernan explores why big organisations so often make big mistakes - and asks if the cure could be the aviation industry's model of a "just culture".

In the past ten years, there have been a string of organizational failures - from BP to the banks, from the Catholic Church to Rotherham. In each instance, hundreds, even thousands of people could see what was going on but acted as though they were blind. Silence ensured the problems continued and allowed them to grow.

The conditions that create the phenomenon called "wilful blindness" are pervasive across institutions, both public and private. Wherever there have been cases of organisational failure you typically find individuals who are over-stretched, distracted and exhausted. They cannot see because they cannot think.

Businesswoman and writer Margaret Heffernan argues that the solution is a "just culture"; which means organizations that encourage people to speak up early and often when things go adrift, without fear of being silenced.
