The Theory of Research Programs by Imre Lakatos

Imre Lakatos (1922-1974) was a Hungarian scholar of Jewish descent who migrated to Britain. His original name was Avrum Lipschitz. He termed his theory of science as "sophisticated falsificationism" because his philosophical views were influenced by both Popper and Kuhn, who also became his main adversaries. Contrary to Popper, who posited that isolated facts could falsify a theory, Lakatos believed that falsification is a complex process, and theories are typically too robust for a mere handful of facts to dismantle them. Falsification is not an instant occurrence but a process, and it is not always successful.

Lakatos contended that scientists create and develop research programs. These programs are intricate constructs, comprising two main components. The most crucial part is its core, which consists of a set of fundamental theories, objectives, and methods. Scientists adhering to a particular research program invariably defend its core. However, since ideal research programs do not exist, each faces difficulties in explaining complex facts. Facts that are hard to account for within the framework of a research program challenge it. Yet, this does not imply that they immediately destroy it. To preserve the program, scientists generate auxiliary hypotheses to account for complex facts in a way that aligns with the program rather than contradicts it. The accumulation of such auxiliary hypotheses forms a protective belt around the core. The protective belt is the second component of a research program. Thus, unlike Popper, who believed that scientists abandon hypotheses under attack from negative facts, Lakatos argued that scientists, in such cases, do not abandon them but rather invest all their efforts into creating auxiliary hypotheses to save the program.

The purpose of a research program is to enhance knowledge. Only under this condition does it contribute to progress and remain meaningful. Although the attack of facts does not falsify a research program outright, it forces scientists to focus more on generating auxiliary hypotheses and constructing the protective belt rather than on advancing knowledge. When scientists expend all their efforts on forming the protective belt and the research program ceases to contribute to knowledge, it loses its significance, scientists become disillusioned, and abandon it. Hence, a research program is falsified not by the facts themselves but by the loss of enthusiasm from the scientists defending it. Nonetheless, Lakatos did not deem falsification as inevitable even in this scenario. If there are scientists who maintain their enthusiasm for the research program and continue to develop it, even when it yields no new knowledge, it is possible that the crisis will pass, attacks will diminish, and the research program may once again begin to generate new knowledge, thus resuming its role and regaining its former significance.
