A lot of senior execs, CxOs and founders have built multi-million dollar careers around their ability to speak at length with complete confidence about topics of which they are clueless. This works because the people who actually know what they are talking about tend to be powerless worker-bees and the people who are fooled by confidence projection tend to be investors and powerful career kingmakers.

The people rolling their eyes when they hear bullshit are not the people writing the checks.
