Which group's opinion is NOT typically involved in influencing public policy?

The average citizen's opinion is not typically involved in influencing public policy through formal mechanisms. While individual citizens can indeed have an impact through voting, grassroots advocacy, or public opinion, their influence is often indirect and less organized compared to the formal strategies employed by government officials, businesses, and interest groups.

Government officials create and implement policies, businesses have significant resources and lobbying power to influence decision-making, and interest groups actively advocate for specific issues or policies, leveraging collective interests and expertise. In contrast, while the average citizen may express opinions or participate in civic activities, their contributions do not usually occur within the same structured and systematic way as those of organized entities. Therefore, the average citizen's role in shaping policy is generally more peripheral and less direct than that of the other groups mentioned.
