President George W. Bush is famous for saying he doesn't pay attention to public opinion polls.
Many reasonable people think that this is arrogant – democratically elected leaders should not flout the will of the people who elect them, critics say.
But perhaps there is some wisdom in Bush's policy against reading polls.
What I'm getting at is: Most people just don't know that much stuff, and polls must reflect that. That is, in many cases, polls are asking people about things they simply don't know very well.
Imagine if a pollster called you and asked, "Is the economy headed for a recession?"
You're smart, sure, but do you know what a recession is? Troll your memory for a second. Formulate a guess.
Going by that most reputable of all sources, Wikipedia, a recession is defined in two ways.
Economists say: "A recession is a decline in a country's real gross domestic product, or negative real economic growth, for two or more successive quarters of a year."
The National Bureau of Economic Research says: "A recession is a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale-retail sales. A recession begins just after the economy reaches a peak of activity and ends as the economy reaches its trough."
Did you guess right?
Knowing whether the American economy is in recession requires knowledge of the definition of "recession," as well as the directions of GDP, and perhaps income, employment, industrial production, and wholesale-retail sales.
Knowing whether the economy is headed for recession requires all that, plus advance knowledge of what will happen in the future.
So you'll excuse my skepticism when I see a poll that announces, "Majority of Americans expect a recession." I don't think the majority of Americans even know what a recession is, let alone whether one is on the horizon.
There are many things that the majority of Americans are expert on: how to speak English, whether they are happy, and whether they like their cars and houses, for instance.
But when a pollster calls and asks the majority of Americans a bunch of questions that baffle economists, we ought not to grant the results much credence.
