More a set of examples than an explanation, but it’s still a good question:
Politicians and journalists sure seem to believe that voters have the attention span and reasoning ability of a two-year old. Convinced that we are unable to hold multiple concepts in our minds long enough to judge how they fit together, you can count on being barraged with disconnected appeals to raw emotions.
Nowhere is this more apparent than in the way Washington concocts its complex tax and regulatory policies, and in the media’s childish analysis. As dumb as they think we are, do politicians really believe that they are smart enough to fine tune the economy, counting on their media enablers to justify ham-handed interventions through sound-bite politics?
Say, isn’t someone having a conference with a panel on this question?
