Stephan Shakespeare: Can a combination of experts and public opinion improve our decision-making processes?
Michael Portillo once told me how in Cabinet he would look around the room and wonder if this group of people around the table were really running the country. He imagined there was a secret door leading to another room in Downing Street where "the real cabinet" was meeting. We probably all share a belief that somewhere there are Wise Ones who, if only we could let them get on with it, would sort things out properly. But where are they?
If we can’t have wisdom, at least we want "evidence-based policy". Well, I refer once again to the amazing evidence of Professor Philip Tetlock, an academic at the University of Pennsylvania who made a 20-year study of the forecasts of 284 experts from academia and practitioners, including viewpoints from Marxists to free-marketeers; 28,000 predictions were tested, and the analysis showed that they were only slightly more accurate than random, and worse than basic computer algorithms. It’s an eye-opening study and if you want to check it out for yourself, here’s the Amazon link.
If expert opinion isn’t reliable, what about public opinion? It may not be informed, deliberated or even truly measurable, and yet it dominates decision-making at every level of government: nobody wants to be seen going against what the voters appear to want. So is that a good alternative, can we trust in the "Wisdom of Crowds"? I suspect a scientific test of that proposition would look a lot like Tetlock’s study: slightly better than random.
I say this as we begin the second two-day YouGov-Cambridge Forum at Magdelene College this morning. Can we combine the Wise Ones with The Crowd to improve the process? That fantasy team of wise and experienced people in a secret room would probably look like our advisory board (including as it does Lord Griffiths, Jonathan Powell, Lord Wilson, Polly Toynbee and Jimmy Wales). And with our partners – Cambridge University, RUSI, the Guardian and the British Council – we are bringing smart, well-informed people together with in-depth opinion research towards our aim of creating an Institute of Public Opinion.
