Which of the following represents an example of subjective norms?

Subjective norms refer to the perceived social pressure to engage or not engage in a particular behavior, which is closely tied to people's beliefs about how others view that behavior. The correct choice highlights beliefs about the approval of friends and family regarding a decision, emphasizing that these social influences can shape an individual’s choices and behaviors.

When individuals consider what their friends and family think about a specific action, they are weighing the social approval or disapproval that might come from their immediate social circle. This reflects the essence of subjective norms, which are influenced by the expectations and beliefs related to what significant others deem acceptable or desirable.

On the other hand, the other options illustrate aspects of individual preferences or societal structures rather than social perceptions. Personal preferences focus on one's individual likes or dislikes, societal laws pertain to formal regulations that govern behavior, and an internal value system is related to personal ethics and morals, none of which directly address the social influence component inherent in subjective norms.
