The Methodology of Scientific Research Programmes

by Imre Lakatos

Summary

Imre Lakatos's "The Methodology of Scientific Research Programmes" argues that scientific progress should be understood not as a series of discrete theories that are individually falsified, but as a succession of "research programmes." These programmes consist of a "hard core" of fundamental assumptions that are protected from refutation by a surrounding "protective belt" of auxiliary hypotheses. When anomalies arise, scientists modify this protective belt rather than abandon the hard core.

The book introduces the concept of "progressive" and "degenerating" research programmes. A progressive programme is characterized by a series of novel predictions and the explanation of existing anomalies, while a degenerating programme merely accommodates anomalies after the fact without offering new insights. Lakatos proposes a historiographical approach to understanding scientific rationality, where the assessment of scientific change relies on comparing competing research programmes rather than evaluating isolated theories.

Key concepts

  • Research ProgrammesA sequence of theories, each containing a hard core of assumptions, a protective belt of auxiliary hypotheses, and a set of heuristics.
  • Hard CoreThe fundamental, irrefutable set of assumptions at the center of a research programme.
  • Protective BeltAuxiliary hypotheses and assumptions surrounding the hard core, designed to be modified or replaced to protect the hard core from refutation.
  • Progressive Research ProgrammeA programme that leads to novel predictions and the explanation of anomalies.
  • Degenerating Research ProgrammeA programme that fails to predict novel facts and primarily explains anomalies after they occur.
  • FalsificationThe process by which a scientific theory or hypothesis is proven false; Lakatos refines this by applying it to research programmes rather than individual theories.
