The Power of Reciprocity Is Used in a Nefarious Way

There is strong evidence that if companies give gifts as small as piza for the office staff, those physicians prescribe that pharmaceuticals, drugs more. The same is true for legislators. So let's say you are consulting now for a pharmocetical firm who wants to use the principles of influence to their gain, but they also want to use them ethically. I tell them to give them non material gifts that will benefit all concerned. But then i think, white paper versus carabbean vacation, and that's hard sell.
