It's possible for a person with superior reasoning to take advantage of someone with inferior reasoning by cheating them out of something. Or perhaps better said, a person may use inferior reasoning that sounds good to the listener in order to achieve some goal which they were aware of by using their own better reasoning. Scams come to mind. Such a thing would depend on poor reasoning or ignorance in the victim, so that would call for people to learn how to better reason in order to combat it.
