Most of the time I think everyone puts some reasoning behind their positions they take. I usually state that I'm trading the range, etc.
Regardless of stating reasons or not, if I'm long and I see everyone saying simply "I'm short", it's going to make me at least look at my own reasoning with fair bit more scrutiny. Being able to have others (in essence) tell you you're wrong and stick to your guns is an extremely valuable talent. Many have gone broke trying to learn it.
All I'm saying is that even if someone does not give any reason for the direction of their trade it will most likely make another person look more closely at their own logic.
