‘Although there are many different types of personalities in the world, and their complexities and differences are fascinating; people’s behaviours, thoughts and feelings are most strongly influenced by the roles they take up and the tasks they undertake. This effect is not experienced consciously and so people tend to think in terms of personality. But, roles and tasks belong to groups and organisations. Everything changes when you are a parent, a government official, a CEO, a nurse, a lawyer or a call centre worker. Tasks and roles “call out” different parts of you. You think different thoughts and different feelings are experienced in different roles and doing different tasks. These may travel across roles, but they are often unique to the role. I am hugely curious about this.’
