Agreed. Unfortunately the businesspeople the author is talking about don't seem to be making the insider/outsider distinction that you're pointing out. Combine that with the fact that most businesspeople have the compulsive need to make their ideas sound more complicated and profound than they really are, and you have the recipe for misunderstanding and miscommunication.
That's precisely right. Unfortunately, this is caused by managers so often rewarding "confidence" instead of competence.
Fortunately, the way out of this is through greater use of data and analysis. I always find it amusing when an overconfident manager s left speechless when you show them the numbers indicating what they just said is bs. Of course, the nice thing about using data is that it makes managerial blowhards think twice before making promises or telling people that they've actually done something great.
