Which of the following is NOT a common characteristic of a crowd?

Predictability is not a common characteristic of a crowd. Crowds are typically characterized by various unstructured behaviors and fluid dynamics, making them inherently unpredictable. Individuals within a crowd react to situational stimuli and to the behaviors and emotions of those around them, resulting in spontaneous and sometimes erratic actions.

In contrast, anonymity, emotionality, and suggestibility are traits often associated with crowds. Anonymity can lead individuals to feel less accountable for their actions within a group, potentially resulting in behaviors they might not exhibit alone. Emotionality reflects how crowds can rapidly shift in moods, often escalating tensions or enthusiasm. Suggestibility highlights how individuals are influenced by the crowd's collective mindset, leading to actions based on group dynamics rather than individual reasoning.
