Yes, it is. And you used it in completely the wrong sense, as its antonym To explain: unless you think you can repeat this exact baseball season thousands of times to observe the "chemistry" in teams, it's absolutely not empirical. I was talking about 10 years of baseball. Observation by various sources backs up that chemistry was existent and mattered somewhat w/ most of the title winners. And yet, there was not a single repetition involved. Completely non-empirical. And there is no objective way of saying anything that could have been observed showed chemistry to be a deciding factor, but that's going back to the start of the thread.
