We would rather cogitate on what we do not know than actually do the things we know we ought to do.
Organizations often suffer from inertia. A company may know they need to improve quality control, so they discuss it, listen to presentations about it, read books, look at state-of-the-art systems -- but never actually get around to doing it. Their problem is one of knowing too much, but doing too little.
Be doers of the word, and not merely hearers.” (James 1:22 NRSV)
