A bad idea is one thing. Flawed execution of a good idea is something else. Thomas Edison is said to have botched the execution of the light-bulb concept about a thousand times before he got it right. Today, we’ve decided that the incandescent light bulb is not such a great idea anymore. But does anyone think that the general concept of converting electrical energy into light is a bad idea?

With changing times and advances in learning and understanding, we’re in constant danger of thinking that all old ideas are bad ideas—and in even greater danger of seeing any flawed execution of an old idea as a failure of the old idea itself. In our hurry to embrace “progress” we often don’t pause and look more carefully at where failure is truly located, and as a result, our piles of obsolete notions include increasing amounts of the wisdom of the ages.

Lately, at least in the West, we’re especially prone to do this with the social sciences. This week’s (or this decade’s) scientific consensus trumps all. And if you’re out of step with it—well, the fact that you’re wrong is self-evident. Because we just don’t do things that way anymore. We know better … until we change our minds again.
