ACT: Why are the Big Two of Agency and Communion so Fundamental to Human Psychology? An Agency-Communion Theory (ACT) and its Novel Account of Social Influence

Research question/goal: 

Agency (influence, resourcefulness, authority) and communion (benevolence, prosociality, honesty) are fundamental dimensions of human social cognition, the self-concept, and personality. These ‘Big Two’ must serve a tremendously important function for humans, otherwise they would not be that fundamental. Yet, what is this function? State-of-the-art answers explain the function of the Big Two either in social cognition or the self-concept or personality, and these answers contradict each other in critical ways. Here, I propose the first all-encompassing answer to the question of what function the Big Two have in social cognition and the self-concept and personality. It comes in the form of a novel theory: Agency-Communion Theory (ACT). ACT’s new perspective on the Big Two entails a wide variety of previously unforeseen behavioural consequences, including a novel conceptualization of social influence. Current theories assume that people have an innate tendency to conform to majority norms. ACT questions the existence of such an innate tendency and offers an alternative with far-reaching implications for many theories across the social sciences and urgent societal challenges in the sphere of social influence. My interdisciplinary team will empirically test ACT and its novel concept of social influence. We will use new, tailor-made methodology in laboratory experiments, formal evolutionary models, Big Data, and panel studies.

Current stage: 

The project now comprises five methodologically different work packages: experiments, agent-based models, panel data, Big Data, and an experience sampling study. We are now in the second year of this 5–6-year project. We have spent most time so far to set up and pretest the studies for all five work packages and to refine the theory (based on the pretest results). Data collection for all five work packages will start shortly.
