when faced with a left or right decision, and little info as to which may be better, players might as well consistently pick the same choice or choose randomly.
If this behavior vexes the DM, he should consider providing them with better information.
Didn't Dante always go left?
My rule of thumb was always "better to be right with right than left with left".
I read an article the other day that was talking about how grocery stores are designed with the idea that most people travel through it counter-clockwise. They almost always go to the right after entering the store. This was in the US though and they said that people in some other countries preferred going to the left instead. They proposed that the behavior may be linked to which side of the road you were used to driving on.
