Economics is at the start of a revolution that is traceable to an unexpected source: medical schools and their research facilities. Neuroscience — the science of how the brain, that physical organ inside one's head, really works — is beginning to change the way we think about how people make decisions. These findings will inevitably change the way we think about how economies function. In short, we are at the dawn of "neuroeconomics."

Efforts to link neuroscience to economics have occurred mostly in just the last few years, and the growth of neuroeconomics is still in its early stages. But its nascence follows a pattern: Revolutions in science tend to come from completely unexpected places. A field of science can turn barren if no fundamentally new approaches to research are on the horizon.

Scholars can become so trapped in their methods — in the language and assumptions of the accepted approach to their discipline — that their research becomes repetitive or trivial.
