Problematic Integration Theory examines how people receive and process messages based on their probabilistic orientations (likelihood of outcomes) and evaluative orientations (positive or negative assessment). Problematic Integration occurs when the two orientations cannot be integrated, resulting in four forms: divergence (conflict between what is wanted and likely), uncertainty (unknown outcomes), ambivalence (having two opposing feelings), and impossibility (difficulty deciding likelihood of desires). The theory was developed in the 1980s and examines message reception on both cognitive and emotional levels to understand human experiences.
