If a transaction weren't in my interest, I wouldn't engage in it. This is a fallacy. People often engage in transactions that aren't in their interest- believing in the moment that they are. Or said another way, there's a difference between long-term interest and short term interest, and people often don't see their long-term interest clearly. Or said still a different way, there's a big difference between happiness and pleasure, and people sometimes engage in pleasure in detriment to their happiness (roughly from the Dalai Lama). I'm not talking about the 10^(-14). I'm talking about real decisions where there is an information asymmetry. And meth.
