Consider Mary Mapes: by all evidence a person totally consumed by delusions of adequacy. Only in the bizarre world of high stakes journalism could a person so immune to facts survive even as long as she did. >>>>>>>>>>>>>>>>
You may be right but a lot of people who are totally immune to facts have had long careers in business management.
In my experience, "managers" tend to be more politically adroit. There are different kinds of reality. On the project I am working on now, I was relieved from a leadership role because I refused to make promises that I could not deliver on, I told the program manager that he was making commitments that he could not deliver on based on misinformation and wishful thinking. I was replaced by people who were more willing to make promises.
In the event, I was proven correct. A good deal of what we shipped was garbage, testing was inadequate or meaningless. I'm now trying to backfill and fix what is essentially junk, though nicely documented and tested.
I refrain from saying "I told you so", because if they had listened to me, we might have gotten our contract canceled. Instead, we have the customer pregnant (actually trying to raise the little bastard) so the customer keeps coming back to its abuser. Am I morally comfortable? Hard to say. Did the company actually do anything unethical? Not intentionally, more engaging in wishful thinking, actual malevolence.
