Speaking of over-reduction, "Does condition X provide a 3 or 4 percent boost?" is pretty much an over reduction - it doesn't even acknowledge that most of these issues aren't even discussed in genuine way - The opposing "sides" are optimizing on different sets of variables. And of course the notions of 2 sides ignores the reality that there are several viewpoints optimizing several different sets of variables and the "left"/"right" distinction is just the result of some sort of really bad clustering algorithm. (Lets temporarily ignore the part where in actual reality, the various groups can't even agree what all the variables are, or how to measure the results).
