This study provides a critical review of the concept of attitudes in social psychology, tracing its evolution from its philosophical origins to contemporary approaches. The tensions between individualistic and collectivist perspectives are examined, as is the complex relationship between attitudes and behaviors. The predictive validity of attitudes is also questioned. It also analyzes critiques from constructionism and discursive theory, which reframe attitudes as social and linguistic constructs rather than stable mental states. The ethical and political implications of using attitudes in social interventions are discussed, too. Finally, it proposes future lines of research oriented toward cultural inclusion, the impact of digital technologies, and the integration of cognitive and discursive approaches. Overall, this analysis highlights the importance of an interdisciplinary and ethical approach to understanding the dynamics of attitudes in complex social contexts.
