Quick Start Guide
Explore how groups make decisions together through interactive simulations.

SDS theory explains how groups combine individual preferences into collective decisions using mathematical rules like majority vote, unanimity, or proportional representation.

Try it: See how different voting rules change group outcomes!

SJS theory models how group members influence each other's continuous judgments (like ratings or estimates) through discussion and persuasion.

Try it: Watch opinions converge or polarize over rounds!
  1. Choose a model: Start with SDS for discrete choices or SJS for continuous judgments
  2. Set parameters: Adjust group size, decision rules, and initial positions
  3. Run simulation: Watch the dynamics unfold in real-time visualizations
  4. Explore results: Compare different scenarios to understand group dynamics
