Even if the intelligence of a single person can be buffeted by framing and other bounds on rationality, this does not mean that we cannot hope for something better from the fruits of many people thinking together--that is, from the collective intelligence in institutions such as history, journalism, and science, which have been explicitly designed to overcome those limitations through open debate and the testing of hypotheses with data.

A person is smart. People are dumb, panicky dangerous animals and you know it.

Harvard psychologist Steven Pinker believes that people are rational. His review of Whose Freedom? by George Lakoff argues that, contrary to Lakoff's emphasis on the form of political speech, rational human beings pay attention to the logic of ideas rather than mere language. Even when individuals don't, he suggests in the quote above, institutions such as journalism lead us back to this rational course.
Current coverage of "LipstickOnAPig-Gate" (more than 1,500 media mentions since Tuesday, according to Google News) suggests, however, that both individuals and the press as an institution are more excited by form than by rational argument.
