Where did you learn your life lessons?

A prejudice doesn't have to apply equally to all members of the group, in order to be rational. It is enough that it increases the probability of being right. In this, it is no different to any other information which is not categorical, but works on the basis of probabilities.

Think of it this way. Let's suppose there are two races identifiable by looking. Race A has a probability of violent crime of 0.1 percent.

Race B has a probability of violent crime of 10 percent. You are a taxi-driver at night in a remote place. Let's say you decide to refuse a lift to a member of Race B.

Are you wronging the members of Race B who comprise the non-violent 90 percent? No. Why not?

Because they don't have a right to associate with you against your will, or to use your property without your consent, in the first place. So the question is not, whether the rationale of prejudice applies equally validly to all affected persons. It is whether you have a right to decide whom to associate with and on what terms.

It is whether it is okay to act on the imperfect information we have. But if it's not, then obviously no-one would have a right to take action in almost all circumstances, and thousands of millions of people would die of starvation.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
