I don't know, madisgram. I've been addicted to "gray" thinking all my life, that is, no terribly stark distinctions and much appreciation of the infinite number of shadings applicable to all human thinking and experience except perhaps mathematics.

And "gray" thinking (I think) is just as problematic as black and white thinking. It makes it MUCH harder to arrive at conclusions and make final judgments. There's ALWAYS something to say for the other side (or sides). "Gray" thinking can well paralyze a person, as I know from bitter experience. If you think in black and white, you make your conclusion (zap!) and move on to the next problem.

At least, that's the way it looks from the "gray" side of the line!
