Brain and behaviour research is increasingly being incorporated into political and policy debate in Britain. It is forcing both left and right to re-examine old assumptionsby Matthew Taylor / September 23, 2009 / Leave a comment
As a schoolboy socialist in a 1970s grammar school, the first political arguments I had were about human nature. My idea of the good society rested on a view of people as collaborative and benign, qualities hidden by the depredations of “the system.”
Working-class Tory mates mocked my naivety. To them we were self-interested. Some succeeded by their efforts, others failed or cheated and would change only if incentivised or compelled.
Yet for most of the 20 years that I have been involved in politics—as a Labour party activist, think-tank director and government adviser under Tony Blair—debates about human nature have been restricted to criminality and other social pathologies, as if only bad people failed to conform to the behavioural model of modern economics. I have never fully bought the idea that people are merely self-interested, rational actors. But during my time in Downing Street, whether we were addressing business regulation or competition in the NHS, the model of Homo economicus seemed to serve well enough: offer people choice and they will act in their own interest and in so doing will make the system work better for everyone. It is not a complete view of human action but it was a useful shortcut, and it had become the prevailing view of most policymakers in the US and Britain.
Today, human nature is back. Political debate is questioning again what shapes and motivates us, who we are as social animals and what we could be. Lying behind this is not just a faltering neoliberal project, but also 30 years of research on human behaviour and the neurological processes that shape it. It can be politically unsettling: some findings seems to undermine important assumptions on both right and left. But while David Cameron has claimed aspects of behavioural economics and neuroscience for his modernising project, these insights can inspire progressives on both sides of politics, producing a new synthesis more nuanced and more solidly based than previous attempts to move beyond left and right.
In truth, virtually no one who studies the brain or behaviour, or philosophises about the mind, accepts the idea of a disembodied rational self inside our heads making all our decisions on the basis of self-interest. But whatever its problems, its advocates could until recently argue that it was the best available model. Their assumptions underpinned the free-market philosophy that brought decades of growth. But, as we…
