On Theory Change in Science The inductivist account of science recognizes five steps which are essential to scientific progress. First, scientists compile a large body of facts from observation and experiment. Using the principle of induction, these facts can be generalized to form the basis for a theory or law. Then, once a theory has been developed, scientists can use the theory as part of a valid logical argument to make new predictions or explanations of phenomena. According to Chalmers, the inductivist account has “a certain appeal” to it, namely, that all of scientific progress can be seen as the result of five fundamental leaps of thought (54). “Its attraction lies in the fact that it does seem to capture in a formal way …show more content…

While induction is only one of the five parts of the inductivist account of science, it is one of the most important steps. Induction is the process by which scientists make a leap of thought from observation to theory, and if induction has flaws, then the new theory must unquestionably contain flaws. Regardless of these errors, a scientist, according to an inductivist philosopher, will still accept a particular scientific theory if it can be validly induced from factual observation and experiment. Unlike inductivists, falsificationists believe that there is no way to conclusively prove that a theory is true. Consequently, they will resist stating that they’ve proved a theory to be true. Instead, falsificationists will consider a theory to be true so long as it has not been proven to be false. Unlike the strict five-step process held by the inductivist account of science, falsificationists hold that scientific progress comes about “by trial and error, by conjectures and refutations” (Chalmers 60). In the falsificationist picture, theory change happens constantly, and this process is what constitutes scientific progress. “It can never be said of a theory that it is true, however well it has withstood rigorous tests, but it can hopefully be said that a current theory is superior to its predecessors in the sense that it is able to withstand tests that falsified those predecessors” (Chalmers
