I thought that this piece, on Pharmalot, was quite interesting:
Psychologists urged to upgrade ethics rules
There's not a whole lot to argue with, there. Indeed, one might even suggest that this stuff is self-evident. I wonder what it is, then, that causes people to do what is intuitively inappropriate? Perhaps it's the notion that "everybody else is doing it"? Or, "well, there's no harm, is there?"?
Or perhaps it doesn't occur to anybody that the marketplace is not a place of excellence, crammed with excellent products, each vying for market share, but is, in fact, a place of shoddy workmanship and products, which require bribery, in order to be sold, because they won't sell on their own merits? Perhaps.
