I've been thinking: What is it that enables a bad idea suddenly to spread across millions of people? Here are some of the things I have in mind:
- In France the National Front is reported as leading all other parties in current opinion polls, having won barely 10 percent of the vote in the 2007 presidential election.
- In January's general election, nearly 40 percent of Greek voters supported Syriza, compared wtih fewer than 5 percent as recently as 2009.
- Since narrowly rejecting indendence in last year's referendum, Scotland's voters have rallied to the Scottish National Party, support for which is now reported at over than 40 percent compared with less than 20 percent at the last general election.
- Most spectacularly, more than 80 per cent of Russians are regularly reported as thinking Vladimir Putin is doing a great job as their president, compared with around 60 percent two years ago.
I am hardly the first to ask this question. There is plenty of research (e.g. de Bromhead et al. 2013) on the economic conditions that foster political extremism, for example. But how do we get from economic conditions to wrong persuasion, exactly? There is the famous Goebbels quote about the "big lie," which is fine as far as it goes but always makes me think: surely there's more to it than this?
If you tell a lie big enough and keep repeating it, people will eventually come to believe it. The lie can be maintained only for such time as the State can shield the people from the political, economic and/or military consequences of the lie. It thus becomes vitally important for the State to use all of its powers to repress dissent, for the truth is the mortal enemy of the lie, and thus by extension, the truth is the greatest enemy of the State.
But it can't be true of all lies. Don't some lies work better than others? What is it that defines the ones that work? My best answer so far to this question is an analogy, which I know is less than proof. But it's a thought-provoking analogy; see what you think.
Last year some behavioural scientists (Strõmbom et al. 2014) finally explained how to herd sheep. There is a sheepdog, instructed by a shepherd, that does the running around. It turns out that there are just two stages. First, the dog must gather the sheep in a single compact group. Once that is done, the second step is to threaten the group from one side; as a group, the sheep will move away from the threat in the opposite direction. That's all there is to it.
The reason why the first step must come first is also of interest: If the dog threatens the sheep without first gathering them in a group, they will scatter in all directions, and that's not what the shepherd wants.
Anyway, there's the answer: Group, then threaten.
People are not sheep, and this is only an analogy. Nonetheless you probably already worked out how I would read this. The shepherds are the political leaders. The dogs that run around for them are the campaign managers and activists. The human equivalent of gathering sheep in a group is to polarize people around an identity that defines an in-group and an out-group. So Scots (as opposed to the English), Greeks (as opposed to the Germans), Russian speakers (as opposed to the rest). Group them, then threaten them, and they will move.
To see how the threat sets the group in motion we need one more thing, an insight from Ed Glaeser. Glaeser (2005) wanted to explain the conditions under which politicians become merchants of hate. He began with a community that has suffered some kind of collective setback. When that happens, people demand an explanation: Who has done this to us? "Us" means the in-group. Political entrepreneurs, he argued, will compete to supply satisfying stories. Often the most satisfying account is one that blames the in-group's misfortune on the alleged past crimes of some out-group: the English, the bankers, the Muslims, the Jews, or the West.
Not only past crimes, however; Glaeser uses the phrase "past and future crimes." In other words, he maintains, politicians often transform these stories into powerful threats by giving them a predictive slant: This is what they, the enemy, have done to us in the past and this is what they will do again if we don't mobilize to stop them first.
Remember: Group, then threaten. The result is mobilization.
