Card 1
The aggregate pattern of many individuals’ political attitudes in a population
Explanation
Researchers treat public opinion as a collective pattern emerging from many individual attitudes measured together.
Common mistake
People often confuse public opinion with the views of vocal minorities rather than the full population.
Card 2
Opinion leaders who first receive media messages and pass them on
Explanation
The two-step flow model states that media influence often travels first to opinion leaders, then to their followers.
Common mistake
Many assume mass media always affect individuals directly, ignoring interpersonal mediation.
Card 3
Fear of social isolation when expressing a minority opinion
Explanation
According to the spiral of silence, people silence themselves when they fear isolation, making the majority seem even stronger.
Common mistake
It is often mistaken for simple shyness, rather than fear of being socially excluded for one’s views.
Card 4
Normative pressure to gain approval and avoid disapproval
Explanation
Normative pressure leads people to align publicly with group norms to be liked or accepted.
Common mistake
People often think conformity is mainly about believing others are right, not about wanting social acceptance.
Card 5
Prefer information outlets that reinforce their existing beliefs
Explanation
Selective exposure means people gravitate toward congenial information that fits what they already think.
Common mistake
It is often confused with simple lack of information rather than an active preference for agreeable content.
Card 6
Interpret and remember information in ways that support prior beliefs
Explanation
Confirmation bias shapes how people notice, interpret, and recall information to protect existing attitudes.
Common mistake
Many think confirmation bias is only about information choice, not biased interpretation and memory.
Card 7
A highly informed, trusted individual who often guides others’ views
Explanation
Opinion leaders are everyday people with more interest and knowledge who influence peers’ opinions.
Common mistake
People often equate opinion leaders only with famous elites, ignoring informal influence in everyday networks.
Card 8
Perceived credibility combining expertise and trustworthiness
Explanation
Credible sources are more persuasive because people see them as both knowledgeable and honest.
Common mistake
Many assume popularity alone guarantees influence, ignoring how crucial credibility is for persuasion.
Card 9
Similarity in social characteristics, values, and backgrounds
Explanation
Homophily means people are more influenced by leaders who resemble them socially and culturally.
Common mistake
It is often misread as perfect ideological agreement rather than broader social similarity.
Card 10
High centrality through numerous and strategically placed social ties
Explanation
Central actors can quickly spread ideas because they connect to many others or bridge groups.
Common mistake
People sometimes assume only the loudest voices matter, ignoring structural network position.
