I took the below information from Wikipedia, whats in yellow is what was of interest to me, as much as I hate arrogant people maybe the guy’s assessment of reality is correct or maybe not. Time will tell.
Reality-based community is an informal term in the United States. In the fall of 2004, the phrase “proud member of the reality-based community” was first used to suggest the commentator’s opinions are based more on observation than on faith, assumption, or ideology. The term has been defined as people who “believe that solutions emerge from judicious study of discernible reality.” Some commentators have gone as far as to suggest that there is an overarching conflict in society between the reality-based community and the “faith-based community” as a whole. It can be seen as an example of political framing.
The source of the term is a quotation in an October 17, 2004, The New York Times Magazine article by writer Ron Suskind, quoting an unnamed aide to George W. Bush (later attributed to Karl Rove):
The aide said that guys like me were “in what we call the reality-based community,” which he defined as people who “believe that solutions emerge from your judicious study of discernible reality.” … “That’s not the way the world really works anymore,” he continued. “We’re an empire now, and when we act, we create our own reality. And while you’re studying that reality—judiciously, as you will—we’ll act again, creating other new realities, which you can study too, and that’s how things will sort out. We’re history’s actors…and you, all of you, will be left to just study what we do.”
