So the next time a salesman gives you a free gift or consultation, or makes a concession of any sort, duck. Don’t let him press your reciprocity button. The best way out, Cialdini advises, is to fight reciprocity with reciprocity. If you can reappraise the salesman’s move for what it is — an effort to exploit you — you’ll feel entitled to exploit him right back. Accept the gift or concession with a feeling of victory — you are exploiting an exploiter — not mindless obligation.

So, we’ve reached the state that George Will described. He said there’s a certain kind of liberal that wants diversity in everything, except thought. And so, we do need certain kinds of diversity. But the key to remember is that, diversity by its very nature is divisive, and so, what’s the function of your group? If your group needs cohesion, you don’t want diversity. If your group needs good, clear thinking and you want people to challenge your prejudices, then you need it. So in the academic world, we need that kind of diversity, and we don’t have it.
