Collective_behavior - Wikiparency

# Collective behavior ## MicroSim spec - **Recommended sim type:** [[Agent-based_model|agent-based model]] - **Microsimmability score:** 78/100 - **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below. ### Parameters (tunable controls) - `Number of agents` - `Imitation strength` - `Noise` ### What animates Many agents copy neighbors with some noise, and group-level order emerges or dissolves. ### Learning objective Explain how local imitation among many agents produces collective patterns. ## Links (Wikipedia order)  `1992_Los_Angeles_riots` · [[Adaptation]] · [[Agent-based_model]] · [[Ant_colony_optimization_algorithms]] · [[Artificial_intelligence]] · [[Artificial_life]] · [[Attractor]] · [[Autopoiesis]] · `Bandwagon_effect` · [[Bifurcation_theory]] · `Billy_Graham` · [[Bounded_rationality]] · [[Cellular_automaton]] · [[Centrality]] · [[Chaos_theory]] · `Cognitive_model` · [[Collective_action]] · `Collective_animal_behavior` · [[Collective_consciousness]] · `Collective_effervescence` · [[Collective_intelligence]] · `Collective_narcissism` · [[Complex_adaptive_system]] · [[Complex_system]] · [[Conversation_theory]] · [[Coupled_map_lattice]] · `Crowd_psychology` · [[Cybernetics]] · [[Dissipative_system]] · [[Dynamic_network_analysis]] · `Economic_bubble` · [[Emergence]] · [[Entropy]] · [[Evolution]] · `Evolution_of_cognition` · [[Evolutionary_computation]] · [[Evolutionary_developmental_biology]] · [[Evolutionary_game_theory]] · [[Evolutionary_robotics]] · [[Evolvability]] · `Existence` · `Extraordinary_Popular_Delusions_and_the_Madness_of_Crowds` · `Fad` · [[Feedback]] · `Floyd_Henry_Allport` · [[Fractal]] · `Franklin_Henry_Giddings` · [[Game_theory]] · [[Genetic_algorithm]] · [[Genetic_programming]] · [[Geomorphology]] · [[Goal_orientation]] · [[Graph_theory]] · `Group_Psychology_and_the_Analysis_of_the_Ego` · `Gustave_Le_Bon` · `Harvard_University_Press` · `Herbert_Blumer` · `Herd_behavior` · [[Herd_mentality]] · [[Homeostasis]] · `Hula_hoop` · [[Information_theory]] · `Jaap_van_Ginneken` · `John_Dollard` · `John_Lofland_(sociologist)` · `Keeping_up_with_the_Joneses` · `Lorenzo_Pareschi` · [[Machine_learning]] · `Mad_Gasser_of_Mattoon` · `Michael_Tomasello` · `Moral_panic` · [[Multistability]] · `Neal_E._Miller` · `Neil_Smelser` · [[Network_motif]] · [[Network_science]] · [[Neural_network_(machine_learning)]] · [[Nonlinear_system]] · [[Operationalization]] · [[Ordinary_differential_equation]] · `Panic_buying` · [[Partial_differential_equation]] · [[Particle_swarm_optimization]] · [[Pattern_formation]] · `Peer_pressure` · [[Percolation]] · `Percolation_theory` · [[Phase_space]] · [[Phase_transition]] · [[Population_dynamics]] · [[Prisoner's_dilemma]] · `Ralph_H._Turner` · [[Rational_choice_model]] · [[Reaction–diffusion_system]] · `Red_Scare` · `Riot` · `Robert_E._Park` · [[Robustness_(computer_science)]] · [[Scalability]] · [[Scale-free_network]] · [[Second-order_cybernetics]] · [[Self-organization]] · [[Self-organized_criticality]] · [[Self-reference]] · [[Self-replication]] · [[Sensemaking]] · `Shared_intentionality` · [[Small-world_network]] · `Social_collectivity` · `Social_comparison_theory` · [[Social_dynamics]] · `Social_learning_theory` · `Social_movement` · [[Social_network_analysis]] · `Social_reality` · `Social_structure` · [[Spatial_ecology]] · `Spiral_of_silence` · [[Swarm_behaviour]] · [[Synchronization]] · [[System_dynamics]] · [[Systems_biology]] · [[Systems_science]] · [[Systems_theory]] · [[Systems_thinking]] · `The_Crowd:_A_Study_of_the_Popular_Mind` · `Theories_of_political_behavior` · `Theory_of_computation` · [[Time_series]] · `Tulip_mania` · `University_of_Chicago` · [[Variety_(cybernetics)]] · `Wall_Street_crash_of_1929` · [[Wayback_Machine]] · `Witch_hunt` > p5.js MicroSim stub · part of Systems Science · [Wikipedia source](https://en.wikipedia.org/wiki/Collective_behavior) > Relation: subfield of systems science. ## Concept summary Collective behavior describes coordinated group-level patterns (flocks, crowds, swarms) that emerge from simple local interaction rules among many individuals. ## Build checklist - [ ] Claim it: set `status: in-progress` + `lease` + `leased_at` - [ ] Write the child page explaining the concept (tie it back to systems science) - [ ] Finalize parameter ranges and defaults - [ ] Implement the p5.js sketch (drawing + control regions) - [ ] Add caption + the learning objective on the page - [ ] Set `status: done` ## p5.js sketch ```javascript // MicroSim: Collective behavior let controls = {}; function setup() { // createCanvas(...); create sliders for the parameters above. } function draw() { // background(...); read controls; render agent-based model; respond live. } ``` --- Back to Systems Science · Wikipedia: [Collective behavior](https://en.wikipedia.org/wiki/Collective_behavior) ---  ## Semiotic profile > *The semiotic universals this article invokes, machine-derived from the crossref — **unverified** (born so).
