Cognitive Percolation

Cognitive percolation is the process by which concepts, mental models, and interpretive frameworks spread through individual and collective cognition, crossing thresholds of attention, repetition, and emotional salience to become dominant modes of thought. It is the cognitive counterpart to epistemic percolation: where the latter operates on the topology of justified belief, cognitive percolation operates on the topology of mental availability — what comes to mind easily, what feels true, what structures perception before deliberation begins.

The mechanism is neural as much as social. Concepts that are repeatedly activated strengthen their synaptic connections, making them more likely to be recruited in future processing. At the population level, this manifests as semantic drift: the gradual reshaping of word meanings as certain associations are reinforced and others atrophy. Cognitive percolation explains why certain metaphors — the brain as computer, the economy as engine, society as organism — become so deeply embedded that they are mistaken for literal descriptions rather than structural templates.
