Most people in politics draw energy from backslapping and shaking hands and all that. I draw energy from discussing ideas. - Al Gore

The flight insurance example highlights another psychological phenomenon that is important to understanding how fear influences our thinking: “probability neglect.” Social scientists have found that when confronted with either an enormous threat or a huge reward, people tend to focus on the magnitude of the consequence and ignore the probability. Consider how the Bush administration has used some of the techniques identified by Professor Glassner. Repeating the same threat over and over again, misdirecting attention (from al-Qaeda to Saddam Hussein), and using vivid imagery (a “mushroom cloud over an American city”). September 11 had a profound impact on all of us. But after initially responding in an entirely appropriate way, the administration began to heighten and distort public fear of terrorism to create a political case for attacking Iraq. Despite the absence of proof, Iraq was said to be working hand in hand with al-Qaeda and to be on the verge of a nuclear weapons capability. Defeating Saddam was conflated with bringing war to the terrorists, even though it really meant diverting attention and resources from those who actually attacked us.

Whether it is called a public forum or a public sphere or a marketplace of ideas, the reality of open and free public discussion and debate was considered central to the operation of our democracy in America’s earliest decades. Our first self-expression as a nation — “We the People” — made it clear where the ultimate source of authority lay. It was universally understood that the ultimate check and balance for American government was its accountability to the people. And the public forum was the place where the people held the government accountable. That is why it was so important that the marketplace of ideas operated independent from and beyond the authority of government. The three most important characteristics of this marketplace of ideas were the following: It was open to every individual, with no barriers to entry save the necessity of literacy. This access, it is crucial to add, applied not only to the receipt of information but also to the ability to contribute information directly into the flow of ideas that was available to all. The fate of ideas contributed by individuals depended, for the most part, on an emergent meritocracy of ideas. Those judged by the market to be good rose to the top, regardless of the wealth or class of the individual responsible for them. The accepted rules of discourse presumed that the participants were all governed by an unspoken duty to search for general agreement. That is what a “conversation of democracy” is all about.
