To what kinds of issues and affairs is public opinions limited?

Public opinions are often limited to issues that are highly visible and resonate with people's daily lives, such as economic conditions, healthcare, education, and social justice. Complex or specialized topics, like foreign policy or scientific debates, may not engage the general populace due to a lack of understanding or interest. Additionally, media coverage can shape and narrow the public discourse, highlighting certain issues while overlooking others. As a result, public opinions may not fully reflect the breadth of societal concerns.
