Public relations aims to serve the public by informing them of key issues, but the relationship is complex. PR needs to understand public opinion and how the public perceives their organization. They must see the public as active participants and put communication at the core of their operations. To truly understand the relationship between PR and the public, we must define concepts like public opinion, polls and surveys, the public sphere, and symmetrical vs. asymmetrical communication. Understanding these concepts provides insight into how PR can best relate to the public.
