As we should probably realize by now, not all tasks are created equal — especially when it comes to making mistakes. For most of the things we do — from brushing our teeth to typing an email — making a mistake is usually relatively innocuous. Sure, we might have to clean a bit of the toothpaste off the sink or retype a word or two, but the world doesn’t blow up. It’s just a bit of extra hassle to recover. By contrast, there are some tasks where the opposite is true: Even a small mistake can have major consequences.
