Sznajd model
From Wikipedia, the free encyclopedia
The Sznajd model or United we stand, divided we fall (USDF) model is a sociophysics model introduced in 2000[1] to gain fundamental understanding about opinion dynamics. The Sznajd model implements a phenomenon called social validation and thus extends the Ising spin model. In simple words, the model states:
- Social validation: If two people share the same opinion, their neighbors will start to agree with them.
- Discord destroys: If a block of adjacent persons disagree, their neighbors start to argue with them.
