Science progresses through ‘paradigm shifts’
The concept of ‘paradigm shifts’ in the progress of science is central to the philosophy detailed within the narrative. A paradigm, as defined in the context, is essentially the entire constellation of beliefs, values, techniques, and so on shared by the members of a given community. Scientific advances occur not as a linear progression of knowledge, but rather through a series of these paradigm shifts. This is to say that the development of science is discontinuous; it occurs through revolutionary changes rather than solely through evolutionary ones…Read&Listen More

Normal science operates within paradigms
In ‘The Structure of Scientific Revolutions,’ the concept of normal science is described as research firmly based within the confines of a prevailing scientific framework or paradigm. Normal science is the period in which the scientific community engages in a set of shared assumptions and methodologies, focusing on solving puzzles that arise within the boundaries of the existing paradigm. The work conducted during this phase is often characterized by incremental progress rather than revolutionary changes, as scientists build on the foundation laid by the accepted paradigm to extend scientific knowledge…Read&Listen More

Anomalies and crises trigger scientific revolutions
Anomalies are seen as violations of the expectations that a scientific paradigm predicts. They are the unexpected occurrences that cannot be explained by the prevailing theory or model. When these anomalies persist and the current paradigm cannot adequately account for them, they begin to erode the confidence in the existing scientific consensus. This stage sets the groundwork for a crisis as more and more scientists start to recognize that the paradigm is no longer capable of explaining the observed phenomena…Read&Listen More

The incommensurability of different paradigms
The concept of incommensurability in scientific paradigms refers to the idea that paradigms are so different from each other in their methods, standards, and premises that they cannot be easily compared or measured using a common set of criteria. This idea suggests that when a paradigm shift occurs, the new paradigm is not simply an extension or refinement of the old, but rather a complete overhaul that changes the fundamental concepts and theoretical structures of the field…Read&Listen More

Scientific revolutions are non-cumulative
Scientific revolutions are characterized by a fundamental shift in the basic concepts and experimental practices of a scientific discipline. Thomas Kuhn argues that these revolutions are non-cumulative, which is to say that they do not simply add new knowledge to the existing framework, but rather replace an older framework or paradigm with a new one that is incommensurable with it. This means that the new paradigm cannot be directly compared to the old one because they involve different sets of concepts and standards…Read&Listen More

The role of the scientific community in paradigm shifts
The scientific community plays a pivotal role in the process of paradigm shifts as described by Thomas Kuhn. The community, which is composed of professionals adhering to a set of shared values, beliefs, and techniques, essentially dictates the rules of normal science. Throughout periods of ‘normal science’, members of this community engage in research that is heavily based on existing scientific paradigms. Their work is aimed at articulating and extending the prevailing paradigm, rather than challenging it. This process involves puzzle-solving within the paradigm’s framework, clarifying areas of ambiguity, and resolving apparent discrepancies within the paradigm’s confines…Read&Listen More
