In psychology, a theory is an abstract and parsimonious representation used to understand, explain, predict, and control the psychology of human beings. Theories differ from models and frameworks: models are specific representations, while frameworks offer general approaches. In this context, a meta-theory is a process more than a structure. It is a process where the researcher critically reflects on different aspects of a theory. For example, the Big Five personality theory can be questioned for its assumption of context-independent traits and reliance on statistical methods like factor analysis. The rise of AI challenges the traditional understanding of theory and meta-theory in psychology, urging a re-evaluation of these concepts in light of new technologies.
