What happens when reality changes but our established ways of understanding it do not? Pierre Bourdieu’s concept of hysteresis and Thomas Kuhn’s theory of scientific revolutions approach this problem from very different intellectual traditions.
Bourdieu is explaining social practice. Kuhn is explaining the historical development of science. Habitus is not a paradigm, and a social field is not a scientific theory. Yet placing the two thinkers side by side reveals a shared problem: practices and systems of thought acquire stability precisely because people become skilled at operating within them. That stability becomes visible when it begins to fail.
Bourdieu: when habitus belongs to yesterday
Bourdieu’s theory of habitus explains how social conditions become durable dispositions. People learn ways of judging situations, anticipating possibilities, and acting effectively inside particular social fields.
Normally, this relationship creates fluency. Habitus fits the field; expectation roughly fits reality.
Hysteresis names the moment when that correspondence weakens. The social field changes faster than the dispositions formed within it. Practices that previously appeared sensible become maladapted because their original conditions no longer exist.
Bourdieu sometimes associated this with a “Don Quixote effect”: like Cervantes’s character imagining himself as a knight in a world where the social reality of knighthood has passed, actors can inhabit categories inherited from a disappearing social order.
Hysteresis therefore reveals something normally hidden. Our practical categories have histories.
Kuhn: normal science, anomalies, and crisis
Thomas Kuhn makes a different argument in The Structure of Scientific Revolutions. Scientific development, he argues, is not simply a continuous accumulation of facts.
During periods of normal science, researchers work within a shared disciplinary framework. Paradigms, exemplars, methodological commitments, instruments, and theoretical assumptions establish legitimate problems and recognizable ways of solving them.
This stability is productive. Scientists do not have to reconsider the foundations of their discipline every morning. They can solve puzzles because many basic assumptions remain fixed.
Trouble begins with anomalies: problems that resist satisfactory solution within the established framework. A single anomaly does not automatically destroy a paradigm. Scientists may initially set it aside, reinterpret it, or assume that further research will solve it. Only particularly serious or accumulating anomalies may produce a crisis, potentially followed by scientific revolution and a reorganization of the disciplinary matrix.
Is a paradigm like a habitus?
Only up to a point.
Both concepts explain how established structures make competent action possible. The Bourdieusian actor has practical mastery of a social game; the Kuhnian scientist learns how legitimate puzzles are recognized and solved. In both cases, mastery can initially make anomalies look like exceptions rather than evidence that the rules themselves are changing.
But the analogy has limits.
Habitus is embodied and socially distributed. It concerns dispositions shaped by trajectories of class, education, institutions, and fields. Kuhn’s paradigm concerns organized scientific practice and shared disciplinary commitments. Kuhn is not primarily explaining why an individual psychologically refuses to change beliefs.
Nor does hysteresis equal scientific crisis. A field can change while an actor’s habitus lags behind it. In Kuhn, crisis occurs within the scientific community when confidence in its existing problem-solving framework is significantly disturbed.
The comparison becomes useful precisely when these differences are preserved.
Both Bourdieu and Kuhn show that knowledge and action require a certain conservatism. We cannot reconsider every assumption before every move. Usually this makes expertise possible.
During periods of rapid transformation, however, yesterday’s expertise can become today’s blindness. The categories that once helped us recognize reality may become the very things preventing us from seeing what has changed.
