Opinions spread across a network into echo chambers, polarization, or consensus. Watch the crowd make up its mind.
Play with the dials. How open-minded are people? Watch a crowd agree or split apart.
8 puzzles. Steer the crowd to consensus, or break it into rival camps.
Ask a question, run the experiment, get the numbers back.
Each node is a person holding an opinion on a single issue, drawn as a point on a blue-to-red scale. People only influence neighbors whose views are close enough to their own, set by a confidence bound. From that one rule the network slides toward consensus, splits into rival camps, or shatters into many small echo chambers.
The simulation runs bounded-confidence opinion models, Deffuant-Weisbuch and Hegselmann-Krause, over Erdos-Renyi, Watts-Strogatz, Barabasi-Albert, and lattice networks. Optional confirmation bias and committed zealots reshape who ends up persuading whom, mirroring how social structure and stubborn minorities steer collective belief.
social is one experiment in the petri-labs collection of small interactive simulations of emergent systems.
