Public Opinion, Propaganda and the Mass Media
What the exam tests
You must explain how public opinion forms, how it is measured, how propaganda works, and what role mass media plays in democracy.
Core rules and concepts
- Public opinion: the aggregate of views held by a significant part of the public on public issues; not simply the majority view.
- Agencies: family, school, peer groups, political parties, interest groups, media, and religious and cultural bodies.
- Measurement: opinion polls, surveys, interviews and referendums; sampling and question wording affect results.
- Propaganda: deliberate, systematic persuasion to influence attitudes; techniques include bandwagon, glittering generalities, card stacking, transfer and name-calling.
- Mass media: print, radio, television, cinema, internet and social media; they inform, educate, set the agenda and act as watchdog, but can spread bias and fake news.
Worked example
'A news channel reports a poll saying 70 per cent support a policy, without giving sample size or question wording.' Reason: the claim is not reliable evidence of public opinion. Check who commissioned the poll, the sample, the margin of error and the exact question. Public opinion is measurable only with transparent methods; a headline percentage is not proof.
Traps
Do not equate public opinion with the view of the majority or with media opinion. Do not say propaganda is always false; it is persuasion, and can use true facts selectively. Do not treat social media as automatically democratic. Do not ignore the distinction between informing and manipulating.
