By that expression, he intended to state that a hard-to-vary explanation provides specific details that fit together so tightly that it is impossible to change any detail without affecting the whole theory. The philosopher and physicist David Deutsch offers a criterion for a good explanation that he considered to be possibly just as important to scientific progress as learning to reject appeals to authority and falsifiability. It can be argued that the criterion hard to vary is closely related to Occam's razor: both imply logical consistency and a minimum of assumptions. The philosopher Karl Popper acknowledged it is logically possible to avoid falsification of a hypothesis by changing details to avoid any criticism, adopting the term an immunizing stratagem from Hans Albert.[3] Popper argued that scientific hypotheses should be subjected to methodological testing to select for the strongest hypothesis.[4]	./cache/en-wikipedia-org-5804.html	./txt/en-wikipedia-org-5804.txt
