The Social Ising Model, a tool from 'sociophysics.'
It treats people's opinions like tiny magnets to study how views spread and shift.
It represents individuals as magnetic 'spins' arranged on a network, uses 'phase transitions' to model sudden opinion flips, and treats media or policy pressure as an external magnetic field nudging everyone one way.
It offers a way to understand how a whole population's mood can tip abruptly from one state to another.
