We don’t need to look far to see the principle in action. We buy something at the overpriced convenience store on the corner because it’s easier than getting in the car and driving to the store where prices are lower. We put our dishes in the sink instead of the dishwasher because one less step is required. We let our teenager text through dinner because it’s easier than inviting an argument by trying to enforce the no-phones rule. We accept the first, minimally credible information we find online about a subject because it’s the easiest way to get our questions answered. And so on.
