Gestalt Switch (Kuhnian)
The sudden, non-incremental reorganization of perception that Thomas Kuhn documented at the center of every paradigm shift—the moment when the duck becomes the rabbit and cannot become the duck again.
Kuhn borrowed a term from perceptual psychology to describe the most distinctive feature of
paradigm shifts: the duck-rabbit gestalt switch, in which an ambiguous image resolves suddenly into either a duck or a rabbit, and the switch, once it occurs, cannot be smoothly reversed. He used this analogy because it captured something about scientific revolutions that the standard model of science as cumulative and rational could not: the transition between paradigms is not the gradual revision of belief but the sudden reorganization of perception itself. The scientist does not first observe the data neutrally and then reinterpret it through a new theoretical lens. The paradigm shapes the observation from the start, and when the paradigm changes, the same data is suddenly organized into a different pattern that carries different implications, requires different methods, and defines different problems. One moment the swinging stone is a body struggling toward its natural resting place. The next moment it is a pendulum exhibiting the regular periodicity that makes
