Social science. Incoherent, excepting economics. In the strict sense of the word in coherent; the various parts do not hang together. As a for instance, the many schools of psychology and their directly opposed findings. You can not hang behaviorism and cognitive psychology together and social science disciplines never seem to throw anything away ( I saw behaviorism taught as late as 2006 though it's main tenets are long refuted. ). Social science does not have underlying theory, just many different theories not well supported or not supported at all. The scientific method is applied poorly in social science. ( economics excepted. ) Also social scientists are always complaining about how hard their subject matter ( humans ) is. You do not hear these complaints from neurologist, human ethologist, and human behavioral ecologist for instance.

True today also.
Natural science is rigorous, coheres, it discipline parts hang together and it has underlying theory that supports the whole discipline. At one time evolutionary biology and molecular cell biology were estranged, but the cell people soon hung their subdiscipline with the evolutionary people. ( E. O. Wilson on the same Charlie Rose show with James Watson! )
