Diffusion S Curve

Definition

The Diffusion S Curve represents the rate at which an innovation spreads or diffuses through a population over time, typically following an 'S' shape pattern where initial growth is slow, followed by rapid uptake before slowing down again as saturation occurs.

Analogy

Picture this curve as riding up and down on a roller coaster ride. At first, you're slowly climbing up (early adopters), then there’s that thrilling fast drop (majority adopters), and finally it slows down towards the end (late adopters).

Related terms

Early Adopter: These are individuals who adopt an innovation early during its diffusion process. They're like the first few people in line for a new roller coaster ride.

Late Majority: These are individuals who adopt an innovation after the average member of society. They're like those who decide to ride the roller coaster only after seeing many others do it safely.

Saturation: This is when nearly all individuals within a social system have adopted an innovation. It's like when everyone has ridden the roller coaster, and there's no one left in line.
