Cass Sunstein — co-author of the hugely influential Nudge and an adviser to President Obama — unveils his new theory of ‘group polarisation’, and explains why, when like-minded people spend time with each other, their views become not only more confident but more extreme
In 2008 Barack Obama greatly benefited from this process, in a way that created extreme enthusiasm for his candidacy. Some of this was planned; his campaign self-consciously promoted social networks that spread favourable information. But some of this was spontaneous. Obama supporters, especially young people, worked hard on their own to take advantage of existing networks and create new ones that would turn curiosity and tentative support into intense enthusiasm and active involvement.
A very different example is provided by Islamic terrorism, which is also fuelled by spontaneous social networks, in which like-minded people discuss grievances with potentially violent results. The terrorism specialist Marc Sageman explains that at certain stages, ‘the interactivity among a “bunch of guys” acted as an echo chamber, which progressively radicalised them collectively to the point where they were ready to collectively join a terrorist organisation. Now the same process is taking place online.’ The major force here is not websites, which people read passively; it consists of Listservs (which enable group emails), blogs and discussion forums, which are crucial in the process of radicalisation. Islamic terrorism is a product, in significant part, of group polarisation.
In the private sector, economic disasters, for individuals and large groups, are often a product of conversations among like-minded people, in which some investment or project seems to be a sure winner. The economic crisis that began in 2008 was a product, in significant part, of a form of group polarisation, in which sceptics about the real estate bubble, armed with statistical evidence, did not receive a fair hearing or were in a sense silenced. The best companies, and the best investors, benefit from internal checks and balances.
Of course, not all extreme movements are bad. Some extreme movements may be desirable even when they result from mechanisms of the sort traced here. And even when they are not desirable, extreme positions can do a great deal of good. Nothing said here is meant to deny these claims. But if extreme movements are to occur, it should be because they are sensible and right and not because of the predictable effects of interactions among the like-minded.
This is an edited extract from Going to Extremes: How Like Minds Unite and Divide by Cass R. Sunstein, published by Oxford University Press on 9 July.

People come looking to feed their own prejudices. The more they eat at the trough of bias, the more they find to like.
I used to disdain the Daily Mail for wasting its writers obvious talent on pedling right wing drivel. But as the true horror of my culpabilitiy in letting Labour come to power in 97 has dawned on me, I have been reading the Mail more and more. I now hate labour with extermist zeal, and the Daily Mail has become my prop, my voice, and my comfort blanket.
It's enough to make you weep.

July 2nd, 2009 5:39pm Report this commentI agree. Thanks for stating the obvious: "much of the time groups of people end up thinking and doing things that group members would never think or do on their own." I believe that is referred to as "mob rule" or i suppose "mob law" fits equally well.
I'm not sure what to think, this article was only a clip from the book so i'm debating comments. Given his closeness to Obama i can't help but wonder if this "new theory" is going to be another BS attempt to bash republicans and conservatives like the Homeland security memo that stated that the greatest threat to U.S. security is right-wingers. Is this going to be another "Paul Krugman" "FoxNews and republican media promotes right-wing extremism" sack of crap?

July 2nd, 2009 6:52pm Report this commentIf I am a believer in manmade global warming, I read Monbiot's articles in The Guardian. If I am a denier, I read Booker's articles in The Telegraph. Doubtless, both columnists make a good living out of reinforcing the preconceived ideas of their respective readerships.
But Cass Sunstein has failed to explore the side effects of what he calls group polarisation. Does it follow that manmade climate change believers are mostly left of centre, while deniers are mostly right of centre? There seems to be a superficial case for supporting this hypothesis, judging by the blogging on the websites.
This means that the individual has to be very careful about choosing unrelated bandwagons merely by political association.

July 3rd, 2009 2:52pm Report this commentAny anthropologists out there? I would think this phenomenon is an extension of basic primate co-operation. Members of a pack can only urge each other on, to a kill for example, if others are suggestible. Potential for group influence is inborn. It's double-edged - members may be urged on to catch the prey in a group effort good for all but if judgement is poor they may race so hard they go over a cliff edge.

July 3rd, 2009 8:37pm Report this commentSurprise, surprise, Mr Nudge spills the beans on the NLP campaign in which the masses were manipulated to an extent, not seen for decades. The cyclic 'logic' goes as follows: put a number of subjectivists in a collective, and hey presto, what we've got is subjective collective opinion. Based on the principle of course that objective truth does not exist or is out of reach of man's limited brain power, and that free will is a myth. Very 'interesting' all.

July 3rd, 2009 9:02pm Report this commentWell, this is very obvious, as Barry says, but maybe not to Americans, who tend as a nation to live inside a large echo chamber, with political opinions that range all the way from A to B. So it's probably a jolly good thing for an Obama advisor to figure tricky stuff like this out.
But there is a perfectly easy way to inoculate yourself against second-hand extremism, and that is systematically to expose yourself to opposing views.
I do this by reading the Grauniad as well as the Telegraph, and as a bonus I get to marvel at the determined irrationality of the contributing readers of both papers.

I notice "conspiracy theories regarding Israel" written off as 'extreme" behavior. I suspect Cass hangs around with a lot of Zionist apologists!

July 9th, 2009 3:23am Report this commentYes, it is obvious and understood in academic circles. But ordinary people do not always consider it or think about it. When in like-minded groups, opposing views are not presented. Then, expressed views get stronger and stronger and convince those who did not feel strongly before. It has to be said, otherwise people won't think of it. They will just think that the opinion and information stream they are exposed to is the truth.
