Everyone seems to be amazed that the flags are still up, six months after the World Trade Center and Pentagon attacks. Have Americans suddenly become more patriotic?
Probably not. More likely, they always have been - they just didn't realize that it was okay to show it.
The muting of open patriotism after the Vietnam era may have been a case of what social scientists call "preference falsification": One in which social pressures cause people to express sentiments that differ from those they really feel.
As social scientist Timur Kuran noted in his 1995 book Private Truths, Public Lies, there are all sorts of reasons, good and bad, that lead people not to show how they truly feel. People tend to read social signals about what is approved and what is disapproved behavior and, in general, to modify their conduct accordingly. Others then rely on this behavior to draw wrong conclusions about what people think, and allow those conclusions to shape their own actions.
Oh, not always - and there are always rebels (though often social "rebels" are really just conforming to a different standard). But when patriotism began to be treated as uncool, people who wanted to be cool, or at least to seem cool, stopped demonstrating patriotism, even if they felt it.
When this happened, other people were influenced by the example. In what's known as a "preference cascade," the vanishing of flags and other signs of patriotism from the homes, cars and businesses of the style-setters caused a lot of other people to go along with the trend, perhaps without even fully realizing it, a trend that only strengthened with the politicization of flag displays in several 1980s political campaigns.
The result was a situation in which a lot of people's behavior didn't really match their beliefs, but merely their beliefs about what was considered acceptable. Such situations are unstable, since a variety of shocks can cause people to realize the difference and to suddenly feel comfortable about closing the gap.
That's what the September 11 attacks did. This time last year, you didn't see many American flags on cars in my faculty parking garage. The people who didn't have them on their cars weren't necessarily unpatriotic - but displaying a flag on one's car was associated with particular political and social categories that aren't especially popular on campuses. After 9/11,enough people started flying flags to make other people feel safe about doing it too. Now you can see a lot of flags on the cars in that garage. Have people become more patriotic? Maybe. But more likely they've just become more willing to show it.
This illustrates, in a mild way, the reason why totalitarian regimes collapse so suddenly. (Click here for a more complex analysis of this and related issues). Such regimes have little legitimacy, but they spend a lot of effort making sure that citizens don't realize the extent to which their fellow-citizens dislike the regime. If the secret police and the censors are doing their job, 99% of the populace can hate the regime and be ready to revolt against it - but no revolt will occur because no one realizes that everyone else feels the same way.
This works until something breaks the spell, and the discontented realize that their feelings are widely shared, at which point the collapse of the regime may seem very sudden to outside observers - or even to the citizens themselves. Claims after the fact that many people who seemed like loyal apparatchiks really loathed the regime are often self-serving, of course. But they're also often true: Even if one loathes the regime, few people have the force of will to stage one-man revolutions, and when preferences are sufficiently falsified, each dissident may feel that he or she is the only one, or at least part of a minority too small to make any difference.
One interesting question is whether a lot of the hard line Arab states are like this. Places like Iraq, Syria, or Saudi Arabia spend a lot of time telling their citizens that everyone feels a particular way, and punishing those who dare to differ, which has the effect of encouraging people to falsify their preferences. But who knows? Given the right trigger, those brittle authoritarian regimes might collapse overnight, with most of the population swearing - with all apparent sincerity - that it had never supported them, or their anti-Western policies, at all.
Perhaps we should think about how to make it so.
