social contagion

Social contagion refers to the phenomenon where behaviors, emotions, or ideas spread from one person to another, similar to the way a virus spreads. This can occur through direct social interactions, online platforms, or community norms. For example, if someone starts using a new fashion trend, their friends may adopt it too. This concept highlights how our social networks influence our decisions and feelings, making us more likely to mimic the actions and emotions of those around us, thus shaping broader social behaviors and cultural changes.
