It's a lot harder to keep your cool than it is to lose it. That's on any work ethic. Even if you're a big producer on a movie set, or whatever, it's a lot harder to be a pro than be a baby on your crew. That's one work ethic to keep in mind, as one bad apple could give five people a bad day, when that one person could've stepped up their own efforts a little more and not bring anyone else down.
The true history of Vietnamese civilian suffering does not fit comfortably into America's preferred postwar narrative - the tale of a conflict nobly fought by responsible commanders and good American boys, who should not be tainted by the occasional mistakes of a few 'bad apples' in their midst.
Is it fair to be suspicious of an entire profession because of a few bad apples? There are at least two important differences, it seems to me. First, no one doubts that science actually works, whatever mistaken and fraudulent claim may from time to time be offered. But whether there are any miraculous cures from faith-healing, beyond the body's own ability to cure itself, is very much at issue. Secondly, the expose' of fraud and error in science is made almost exclusively by science. But the exposure of fraud and error in faith-healing is almost never done by other faith-healers.
Business executives need to start by spelling out and communicating their values. Then they need to lead by example. This means getting rid of the bad apples and declining opportunities that bring instant wealth at the cost of selling one's soul.
