More often than not, both people are wrong.
That's a sweeping generalization that I'm not sure you can apply to every (or any) situation.
In Politics for example, it seems that most the time people are wrong, but I'd think it a little silly to say that in all forms of discourse (especially among Academia), everybody is wrong.
http://www.youtube.com/watch?v=sZwfNs1pqG0Here is an interesting video we were shown in Sociology Class about how the famous Prison Experiment of 1979 in the basement of Stanford University. In this experiment, completely healthy people (who underwent a battery of Psychological Exams beforehand) were randomly selected to be either a guard or a "prisoner" in the Stanford University Basement. The guards knew the prisoners had done nothing "wrong", and that the whole thing was just an experiment; no explicit instructions were given.
Within 2 days, the guards had resorted to physical abuse, within 4 days it became sexual abuse and even worse.
These are ordinary people, who knew the "prisoners" were ordinary people just like them, but through their position of power and perceived superiority became brutal and violent towards innocent people.
So tell me again how prisons are such a great place.
I'm implying nothing; I'm coming right out and saying it: there is no objective truth.
Then you're wasting my and everybody else's time even having a discussion. If there's no truth to be found, then why does it matter what anybody thinks?
