That’s because there’s pretty good evidence that we generally don’t truly want good information — but rather information that confirms our prejudices. We may believe intellectually in the clash of opinions, but in practice we like to embed ourselves in the reassuring womb of an echo chamber.
One classic study sent mailings to Republicans and Democrats, offering them various kinds of political research, ostensibly from a neutral source. Both groups were most eager to receive intelligent arguments that strongly corroborated their pre-existing views.
... The effect of The Daily Me would be to insulate us further in our own hermetically sealed political chambers. One of last year’s more fascinating books was Bill Bishop’s “The Big Sort: Why the Clustering of Like-Minded America is Tearing Us Apart.” He argues that Americans increasingly are segregating themselves into communities, clubs and churches where they are surrounded by people who think the way they do.
Almost half of Americans now live in counties that vote in landslides either for Democrats or for Republicans, he said. In the 1960s and 1970s, in similarly competitive national elections, only about one-third lived in landslide counties.
“The nation grows more politically segregated — and the benefit that ought to come with having a variety of opinions is lost to the righteousness that is the special entitlement of homogeneous groups,” Mr. Bishop writes.
