There is a power higher than just that of the 'boss' - and that would be one's own professional ethics and desire and drive to seek and get at the truth.
That - and peer review.
The boss, after all, could be a complete idiot, whereas, in a peer review (before being subsequently published in a technical journal) can be an even tougher and more demanding ordeal.
I'm sure the FBI agents flaming children at Waco were really worried about peer pressure. Yeah sure. Try again. What's your point?
