Quote from Masters of illusion: The great management consultancy swindle

But consultants also know that an outrageously unjustified level of self-confidence can add several points to one’s perceived expertise quotient.

The most important of the all-too-human functions of shaman-consultants is to sanctify and communicate opinion. Like ministers of information, consultants condense the message, smooth out the dissonances, unify the rhetoric, and then repeat and amplify it ad nauseam through the client’s rank and file. The chief message to be communicated is that you will be expected to work much harder than you ever have before and your chances of losing your job are infinitely greater than you ever imagined.

So good. Perfectly describes some of the consultants I have come across.
