I am not sure where I read the psych study (citation anyone?), but I remember reading that a really effective method for getting someone to change their mind was actually to get the other person to frame their argument as a question. E.g., "What questions would you ask me to convince me that you are correct?" It opens up the argument so they are less defensive, since they started with a question instead of an argument.
