Ignorance Versus Stupidity, by Walter E. Williams

If you’re smart, you’ll realize you’re ignorant, and that doesn’t make you stupid. From Walter E. Williams at theburningplatform.com:

One of the most challenging and important jobs for an economics professor is to teach students how little we know and can possibly know. My longtime friend and colleague Dr. Thomas Sowell says, “It takes considerable knowledge just to realize the extent of your own ignorance.” Nobel laureate Friedrich August von Hayek admonished, “The curious task of economics is to demonstrate to men how little they really know about what they imagine they can design.” The fact that we have gross ignorance about how the world operates is ignored by the know-it-all elites who seek to control our lives. Let’s look at a few examples of the world’s complexity.

According to some estimates, there are roughly 100 million traffic signals in the U.S. How many of us would like the U.S. Congress, in the name of public health and safety, to be in charge of their actual operation? Congress or a committee it authorizes would determine the length of time traffic lights stay red, yellow and green and what hours of the day and at what intersections lights flash red or yellow. One can only imagine the mess Congress would create in the 40,000 cities, towns and other incorporated places in the U.S. But managing traffic lights and getting good results is a far less complex task than managing the nation’s health care system and getting good results, which Congress tries to do.

Here’s another task I’d ask whether you would like Congress to control. The average well-stocked supermarket carries 60,000 to 65,000 different items. Walmart carries about 120,000 different items. Let’s suppose Congress puts you in total control of getting just one item to a supermarket, say apples. Let’s not make it easy by having the help of apple wholesalers. Thus, you would have to figure out all of the inputs necessary to get apples to your local supermarket.
