  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 $\mu
q$, where $0 < \mu < 1$ 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 also
highlight the effects of an individual social anxiety attenuation level in
enhancing group consensus and inducing exuberant collective phenomena in
complex systems.
