A lot of people have let me know they wished I had been speaking out on public affairs long before now. But in the aftermath of a very divisive elect… - Al Gore

"Television's ability to evoke the fear response is especially significant because Americans spend so much of their lives watching TV. An important explanation for why we spend so much time motionless in front of the screen is that television constantly triggers the "orienting response" in our brains.

As I noted in the introduction, the purpose of the orienting response is to immediately establish in the present moment whether or not fear is appropriate by determining whether or not the sudden movement that has attracted attention is evidence of a legitimate threat. (The orienting response also serves to immediately focus attention on potential prey or on individuals of the opposite sex). When there is a sudden movement in our field of vision, somewhere deep below the conscious brain a message is sent: LOOK! So we do. When our ancestors saw the leaves move, their emotional response was different from and more subtle than fear. The response might be described as "Red Alert! Pay attention!".

Now, television commercials and many action sequences on television routinely activate that orienting reflex once per second. And since we in this country, on average, watch television more than four and a half hours per day, those circuits of the brain are constantly being activated.

The constant and repetitive triggering of the orienting response induces a quasi-hypnotic state. It partially immobilizes viewers and creates an addiction to the constant stimulation of two areas of the brain: the amygdala and the hippocampus (part of the brain's memory and contextualizing system). It's almost as though we have a "receptor" for television in our brains."

In the 1950s, John Kenneth Galbraith first described the way in which advertising altered the classical relationship by which supply and demand are balanced over time by the invisible hand of the marketplace. Modern advertising campaigns, he pointed out, were beginning to create high levels of demand for products that consumers never knew they wanted, much less needed. The same phenomenon Galbraith noticed in the commercial marketplace is now the dominant fact of life in what used to be America’s marketplace for ideas. The inherent value or validity of political propositions put forward by candidates for office is now largely irrelevant compared with the image-based advertising campaigns they use to shape the perceptions of voters. And the high cost of these commercials has radically increased the role of money in American politics — and the influence of those who contribute it.

We must acknowledge that the utter poverty of hundreds of millions of people is not a matter for compassion only, but a threat in the long term to the growth and vigor of the global economic system. We must see it as a part of our charge to help create economic opportunity so that the gap between the richest and poorest does not grow ever wider.
