In sociology, social action, also known as "Weberian social action" refers to an act which takes into account the actions and reactions of individuals (or 'agents').
According to Max Weber, "an Action is 'social' if the acting individual takes account of the behavior of others and is thereby oriented in its course".(Secher 1962)
