Cultivation theory (Gerbner & Gross, 1976)

Heavy, long-term exposure to a consistent symbolic world gradually cultivates the audience's conception of reality to match that world — heavy TV viewers overestimate crime and distrust others (the "mean world syndrome"). The effect is slow, cumulative, and about baseline worldview, not single messages.

Formula (cultivation differential). CD = P(TV-answer | heavy viewer) - P(TV-answer | light viewer), where P(TV-answer | .) is the share of a viewing group giving the answer that matches television's depiction rather than statistical reality. A positive CD is the measured cultivation.

Transfer. Cultivation is the mechanism that turns volume of consistent output into a shifted sense of "normal." A single agent can now emit enough uniform artifacts to cultivate a niche's baseline — which cuts both ways. The opportunity: make your recurring depiction the audience's default reality. The hazard: AI-homogenized content cultivates a flattened, mean-world sameness across the whole feed, and the reader recalibrates "normal" downward — the macro version of slop.
