Hello Suesa. I enjoyed your post. Concrete thinking can be considered a developmental issue. Tolerance of ambiguity exists along a contituum as a mental health issue. For example, sometimes you have to make decisions based on imperfect data. Moreover, science is rarely settled. Theories are only the best thing until a breakthrough in scientific thought is achieved and we get the next best approximation of reality. There are usually multiple interpretations of evidence based on statistical analyses and sound judgment. For many, the bottom line is vested interest and worldview.

I apologize for the late comment. I read your post thoroughly and agree with you on almost everything...
