A friend of mine has lent me an old copy of the London Review of Books (December 2008 – such are the luxuries of an island paradise). Part of a letter it published caught my attention:
This is what I remember [Chistopher Isherwood] saying about Klaus Mann:
‘Klaus was in despair, always, but in the 1940s, during the days of the Stockholm Peace Pledge, he and many other famous European intellectuals and artists set up a plan for all of them – in protest against the development of atomic bombs – to create and sign a document of protest in which they would declare their agreement to kill themselves on a certain specific date. This mass suicide of artists and intellectuals would draw attention in all the news media all around the world and the impact would bring peace for ever’
It turned out that Klaus Mann was the only one of those who had pledged to kill themselves on the set date who did kill himself on that date. His death received little attention anywhere.
Economists will recognise the pledge made by Mann and his fellow (apparently exceedingly optimistic) intellectuals and artists as a version of the Prisoner’s Dilemma. It appears as if each of the people involved welshed on the promise to kill themselves in the hope that enough of the others would still do so to bring about their desired outcome, namely unilateral disarmament of nuclear capabilities.
What interests me is why Klaus Mann didn’t do the same. I think it has something to do with the power of an idea to motivate action, even when it appears to fly in the face of rationality. Resistance movements very often are characterised by this: think of the Maji Maji rebellion, for example, or John Chilembwe’s rising in Malawi. These were resistance actions that were objectively almost certain to fail (as they did). Still, many gave their lives in support of them. This isn’t something economics deals with very well, which is why, for all the proliferation of economists dealing with conflict, we should never let go of the importance of historical and sociological analysis of motivation.
