I've written in the past about what we should do when we learn that something we have long believed turns out not to be true. (In brief, strive to change those beliefs to be more in line with reality. Doesn't that sound easy?)

But where do these beliefs come from in the first place? Why do we believe them?

On a personal level, according to the brain and linguistical research work of George Lakoff and others (see "Don't Think of an Elephant," and "The Political Brain") it all comes down to "framing."

One of the talks I most enjoy giving is about Strauss and Howe's generational theory of American history. Their work ("Generations: the history of America's future," and "the Fourth Turning") details the interactions of four distinct generational types. These types follow each other repeatedly, making a predictable cycle of historical moods.

It was just a matter of time.

Libraries generate a lot of traffic - from 1,000 to 2,000 people a day depending on the library's size. Our patrons represent a good cross-section of the community.

Library users tend to be engaged in other ways. For instance, many of them are registered to vote.
