There are some things in business that are hard to research, and they are that way for very practical reasons. People don’t like to admit when they make mistakes. You might hear executives spouting the vapid bromide“fail fast, fail often,” but you’re not going to hear them speak in detail of those failures when it affects their careers. It is, to use another vapid bromide, career limiting. As a result, when a study poses the question, “how have you screwed up your part of your business lately?” people are less than enthusiastic about answering honestly.
