Most RPers seem to use it quite freely, and BPers seem to think there is no way it is acceptable.

From this, it seems that RPers have a baseline stance when evaluating people, and believe something about them until proven otherwise. BPers say no evaluation can be made until you have specific instances. The latter seems to be impractical in many cases, and outright impossible in some.

If you never use inductive reasoning, how do you get by? If you use inductive reasoning in some cases but not others, what allows you to make that transition from permissible to prohibited? After all it is only probabilistic anyway, what makes it invalid after a certain point if it is proven to be predictive enough?
