As　one　of　the　most　widespread　social　dynamics,　cooperative　behavior　is　among　the　most　fascinating　collective　phenomena.　Several　animal　species,　from　social　insects　to　human　beings,　feature　social　groups　altruistically　working　for　a　common　benefit.　This　collaborative　conduct　pervades　the　actions　and　opinions　of　individuals,　yielding　strategic　decision-making　between　political,　religious,　ethnic,　and　economic　social　puzzles.　Here,　we　explore　how　cooperative　behavior　phenomena　impact　collective　opinion　dynamics　and　entropy　generation　in　social　groups.　We　select　a　random　fraction　f　of　community　members　as　collaborative　individuals　and　model　the　opinion　dynamics　using　a　social　temperature　parameter　q　that　functions　as　a　social　anxiety　noise.　With　probability　q,　regular　individuals　oppose　their　companions　about　a　social　decision,　assuming　group　dissent.　Collaborative　agents　experience　a　reduced　effective　social　noise　μq,　where　0＜μ＜1　is　the　social　anxiety　noise　sensibility　parameter　that　enhances　social　validation.　We　perform　numerical　simulations　and　mean-field　analysis　and　find　the　system　undergoes　nonequilibrium　order–disorder　phase　transitions　with　expressive　social　entropy　production.　Our　results　highlight　the　effects　of　a　social　anxiety　attenuation　level　in　improving　group　consensus　and　the　emergence　of　cooperative　dynamics　as　a　natural　maximization　of　entropy　production　in　noisy　social　groups,　thus　inducing　exuberant　collective　phenomena　in　complex　systems.　©　2024　Elsevier　Ltd
