Theories play a descriptive role by outlining the qualities of subjects being studied. They serve an explanatory function by clarifying how and why phenomena occur. Theories also offer a predictive role, foreseeing future occurrences based on known variables. Furthermore, they have a heuristic function, stimulating further research and new discovery pathways. Lastly, they fulfill a normative role, guiding practical applications and informing policy decisions.
