Public opinion

Public opinion is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Public opinion rather than just read about it. In short: Public opinion, or popular opinion, is the collective opinion on a specific topic or voting intention relevant to society. It is the people's views on matters affecting them.

Key takeaways

  • Public opinion belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Public opinion to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Public opinion from memory before moving on to harder problems.

Reference excerpt

Public opinion, or popular opinion, is the collective opinion on a specific topic or voting intention relevant to society. It is the people's views on matters affecting them. In the 21st century, public opinion is heavily influenced by the media; many studies have been undertaken which look at the different factors which influence public opinion. Politicians and other people concerned with public opinion often attempt to influence it using advertising or rhetoric. Opinion plays a vital role in making some critical decisions. Sentiment analysis or opinion mining is a method used to mine the thoughts or feelings of the general population. One of the struggles of public opinion is how it can be influenced by misinformation.

Etymology The term "public opinion" was derived from the French opinion publique, which was first used in 1588 by Michel de Montaigne, one of the most significant philosophers of the French Renaissance, in the second edition of his famous Essays (ch. XXII). The French term also appears in the 1761 work Julie, or the New Heloise by Jean-Jacques Rousseau. Precursors of the phrase in English include William Temple's "general opinion" (appearing in his 1672 work On the Original and Nature of Government) and John Locke's "law of opinion" (appearing in his 1689 work An Essay Concerning Human Understanding).

History The emergence of public opinion as a significant force in the political realm dates to the late 17th century, but opinion had been regarded as having singular importance much earlier. Medieval fama publica or vox et fama communis had great legal and social importance from the 12th and 13th centuries onward. Later, William Shakespeare called public opinion the "mistress of success" and Blaise Pascal thought it was "the queen of the world". In his treatise, An Essay Concerning Human Understanding c, John Locke considered that man was subject to three laws: the divine law, the civil law and most importantly in Locke's judgement, the law of opinion or reputation. He regarded the latter as of the highest importance because dislike and ill opinion force people to conform in their behaviour to social norms; however he did not consider public opinion as a suitable influence for governments. In his 1672 essay On the Original and Nature of Government, William Temple gave an early formulation of the importance of public opinion. He observed that "when vast numbers of men submit their lives and fortunes absolutely to the will of one, it must be force of custom, or opinion which subjects power to authority". Temple disagreed with the prevalent opinion that the basis of government lay in a social contract and thought that government was merely allowed to exist due to the favour of public opinion. The prerequisites for the emergence of a public sphere were increasing levels of literacy which was spurred on by the Reformation, which encouraged individuals to read the Bible in the vernacular, and the rapidly expanding printing presses. During the 18th century, religious literature was replaced by secular literature, novels and pamphlets. In parallel to this was the growth in reading societies and clubs. At the turn of the century the first circulating library opened in London and the public library became widespread and available to the public.

Public opinion in British politics

Coffee-houses

An institution of central importance in the development of public opinion was the coffee-house, which became widespread throughout Europe in the mid-17th century. Although Charles II later tried to suppress the London coffeehouses as "places where the disaffected met, and spread scandalous reports concerning the conduct of His Majesty and his Ministers", the public flocked to them. For several decades following the Restoration, the Wits gathered round John Dryden at Will's Coffee House in Russell Street, Covent Garden. The coffee houses were great social levellers, open to all men and indifferent to social status, and as a result associated with equality and republicanism. More generally, coffee houses became meeting places where business could be carried on, news exchanged and The London Gazette (government announcements) read. Lloyd's of London had its origins in a coffeehouse run by Edward Lloyd, where underwriters of ship insurance met to do business. By 1739, there were 551 coffeehouses in London. Each attracted a particular clientele divided by occupation or attitude, such as Tories and Whigs, wits and stockjobbers, merchants and lawyers, booksellers and authors, men of fashion or the "cits" of the old city center. Joseph Addison wanted to have it said of him that he had "brought philosophy out of closets and libraries to dwell in clubs and assemblies, at tea tables and in coffee houses". According to one French visitor, Antoine François Prévost, coffeehouses, "where you have the right to read all the papers for and against the government", were the "seats of English liberty".

Worked examples

Example 1 — a first encounter with Public opinion

Start with the simplest possible case. Write down what Public opinion claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Public opinion before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Public opinion ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Public opinion

In research
Public opinion appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Public opinion in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Public opinion is common in secondary-school and first-year university syllabi. It links to neighbouring topics Belief, Cultural trends, Political science, so understanding it makes those chapters shorter.
In everyday life
Look for Public opinion outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
