This is cool but flawed. "I might change my mind if the speaker makes a good point" . There are a lot of eloquent and convincing speakers. A lot of folks with great speech not until you give it a time and think it through, it is not enough to change your mind on any matter. "It is better to say I will consider to think it through, maybe It will change my mind". Who says it first and repeatedly is now what changes people's mind. A paradigm shift for definition of truth.
