A research program is a sequence of theories in a particular field of science. It is characterized by a "hard core" of fundamental principles that are protected from direct testing and a "protective belt" of auxiliary theories that are modified to connect the hard core to empirical data and make predictions.
This video explains Imre Lakatos's theory of "research programmes" as a way to understand the philosophy of science. It contrasts Lakatos's ideas with those of Karl Popper and Thomas Kuhn, arguing that research programmes offer a more sophisticated development of falsificationism and a rational methodology for scientific progress. The video details the structure of research programmes (hard core and protective belt), their negative and positive heuristics, and how they can be judged as progressive or degenerating. It also discusses challenges and potential limitations of Lakatos's theory, concluding with a suggestion for combining Lakatos's and Kuhn's concepts.
