Convenience is the most underestimated and least understood force in the world today. As a driver of human decisions, it may not offer the illicit thrill of Freud’s unconscious sexual desires or the mathematical elegance of the economist’s incentives. Convenience is boring. But boring is not the same thing as trivial.

In the developed nations of the 21st century, convenience — that is, more efficient and easier ways of doing personal tasks — has emerged as perhaps the most powerful force shaping our individual lives and our economies. This is particularly true in America, where, despite all the paeans to freedom and individuality, one sometimes wonders whether convenience is in fact the supreme value.

As Evan Williams, a co-founder of Twitter, recently put it, “Convenience decides everything.” Convenience seems to make our decisions for us, trumping what we like to imagine are our true preferences. (I prefer to brew my coffee, but Starbucks instant is so convenient I hardly ever do what I “prefer.”) Easy is better, easiest is best.

Convenience has the ability to make other options unthinkable. Once you have used a washing machine, laundering clothes by hand seems irrational, even if it might be cheaper. After you have experienced streaming television, waiting to see a show at a prescribed hour seems silly, even a little undignified. To resist convenience — not to own a cellphone, not to use Google — has come to require a special kind of dedication that is often taken for eccentricity, if not fanaticism.
