. . . humans are social animals and communication plays an important role in decision-making. We frame out thinking in terms of narratives. And able leaders - whether in business, in politics, or in everyday life - make decisions, both personal and collective, by talking with others and being open to challenge from them. Humans, uniquely, produce artefacts of extraordinary complexity and are able to do so only by the successful development of networks of trust, cooperation and coordination. Market economies function only by virtue of being embedded in a social context.
