Question

Quizplus · Accepted Answer

Observers have limited perceptual capacity and may miss important details or interpret actions incorrectly. Additionally, people may hide their true motives or behave in ways that are socially desirable rather than reflective of their true feelings. Finally, observers may oversimplify or distort what they see and hear, failing to understand the complexity of social interactions. Therefore, it is not sufficient to rely solely on observation and listening in social psychological research.
