The blue curve is broken into sections of adopters. Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread. The theory was popularized by Everett Rogers in his book Diffusion of Innovations, first published in 1962. [1]
To describe and understand global cascades, a network-based threshold model has been proposed by Duncan J. Watts in 2002. [1] The model is motivated by considering a population of individuals who must make a decision between two alternatives, and their choices depend explicitly on other people's states or choices.
Flow state theory suggests that when individuals are in a state of flow, they experience deep immersion, focus, and intrinsic motivation in their activities. [52] In the context of education, flow has been associated with increased student engagement, which is a key determinant of learning success.

It is similar to, but distinct from herd behavior. [1] [2] [3] An information cascade is generally accepted as a two-step process.

These changes are generally favorably perceived by the members of the group because they usually are more in line with the values and needs of the ...
The process of adoption over time is typically illustrated as a classical normal distribution or "bell curve". The model calls the first group of people to use a new product "innovators", followed by "early adopters". Next come the "early majority" and "late majority", and the last group to eventually adopt a product are called "laggards" or ...
