Outsiders and Double Vision

Today would be Richard Wright's 104th birthday. Here is a passage from The Outsider that ties in directly with the claim I make about Einstein.

Negroes, as they enter our culture, are going to inherit the problems we have, but with a difference. They are outsiders and they are going to know that they have these problems. They are going to be self-conscious; they are going to be gifted with a double vision, for, being Negroes, they are going to be both inside and outside of our culture at the same time. Every emotional and cultural convulsion that ever shook the heart and soul of Western man will shake them. Negroes will develop unique and specially defined psychological types. They will become psychological men, like the Jews . . . They will not only be Americans or Negroes; they will be centers of knowing, so to speak . . . The political, social, and psychological consequences of this will be enormous.

Is he correct? Do outsiders necessarily become psychological types?
