“Numerous other problems help account for why there has been so little positive change in workplaces or careers. Here’s one of the more important: There are no “barriers to entry” into the leadership industry; no credentials, rigorous research, knowledge of the relevant scientific evidence, or anything else required to pass oneself off as a leadership expert. Anyone and everyone can write a book, be a leadership speaker or a blogger, offer consulting and advice, or start a leadership-development or consulting firm.” (p. 24)
