A political spectrum is a system to characterize and classify different political positions in relation to one another. These positions sit upon one or more geometric axes that represent independent political dimensions. [1] The expressions political compass and political map are used to refer to the political spectrum as well, especially to popular two-dimensional models of it. [2] [3] [4] [5]
Most long-standing spectra include the left–right dimension as a measure of social, political and economic hierarchy which originally referred to seating arrangements in the French parliament after the Revolution (1789–1799), with radicals on the left and aristocrats on the right. [1] [6] While communism and socialism are usually regarded internationally as being on the left, conservatism and reactionism are generally regarded as being on the right. [1] Liberalism can mean different things in different contexts, being sometimes on the left (social liberalism) and other times on the right (conservative liberalism or classical liberalism). Those with an intermediate outlook are sometimes classified as centrists. Politics that rejects the conventional left–right spectrum is often known as syncretic politics. [7] [8] This form of politics has been criticized as tending to mischaracterize positions that have a logical location on a two-axis spectrum because they seem randomly brought together on a one-axis left–right spectrum.
Some political scientists have noted that a single left–right axis is too simplistic and insufficient for describing the existing variation in political beliefs and include other axes to compensate for this problem. [1] [9] Although the descriptive words at polar opposites may vary, the axes of popular biaxial spectra are usually split between economic issues (on a left–right dimension) and socio-cultural issues (on an authority–liberty dimension). [1] [10]
The terms right and left refer to political affiliations originating early in the French Revolutionary era of 1789–1799 and referred originally to the seating arrangements in the various legislative bodies of France. [6] As seen from the Speaker's seat at the front of the Assembly, the aristocracy sat on the right (traditionally the seat of honor) and the commoners sat on the left, hence the terms right-wing politics and left-wing politics. [6]
Originally, the defining point on the ideological spectrum was the Ancien Régime ("old order"). "The Right" thus implied support for aristocratic or royal interests and the church, while "The Left" implied support for republicanism, secularism and civil liberties. [6] Because the political franchise at the start of the revolution was relatively narrow, the original "Left" represented mainly the interests of the bourgeoisie, the rising capitalist class, with notable exceptions such as the proto-communist François-Noël Babeuf. Support for laissez-faire commerce and free markets were expressed by politicians sitting on the left because these represented policies favorable to capitalists rather than to the aristocracy, but outside parliamentary politics these views are often characterized as being on the Right.[ citation needed ]
The reason for this apparent contradiction lies in the fact that those to the left of the parliamentary left, outside official parliamentary structures (such as the sans-culottes of the French Revolution), typically represent much of the working class, poor peasantry and the unemployed. Their political interests in the French Revolution lay with opposition to the aristocracy and so they found themselves allied with the early capitalists; however, this did not mean that their economic interests lay with the laissez-faire policies of those representing them politically.[ citation needed ]
As capitalist economies developed, the aristocracy became less relevant and were mostly replaced by capitalist representatives. The size of the working class increased as capitalism expanded and began to find expression partly through trade unionist, socialist, anarchist, and communist politics rather than being confined to the capitalist policies expressed by the original Left. This evolution has often pulled parliamentary politicians away from laissez-faire economic policies, although this has happened to different degrees in different countries, especially those with a history of issues with more authoritarian-left countries, such as the Soviet Union or China. Thus, the word "Left" in American political parlance may refer to "liberalism" and be identified with the Democratic Party, whereas in a country such as France these positions would be regarded as relatively more right-wing, or centrist overall, and "left" is more likely to refer to "socialist" or "social-democratic" positioned rather than "liberal" ones.[ citation needed ]
For almost a century, social scientists have considered the problem of how to best describe political variation.
In 1950, Leonard W. Ferguson analyzed political values using ten scales measuring attitudes toward: birth control, capital punishment, censorship, communism, evolution, law, patriotism, theism, treatment of criminals and war. Submitting the results to factor analysis, he was able to identify three factors, which he named religionism, humanitarianism and nationalism. He defined religionism as belief in God and negative attitudes toward evolution and birth control; humanitarianism as being related to attitudes opposing war, capital punishment and harsh treatment of criminals; and nationalism as describing variation in opinions on censorship, law, patriotism and communism.
This system was derived empirically, as rather than devising a political model on purely theoretical grounds and testing it, Ferguson's research was exploratory. As a result of this method, care must be taken in the interpretation of Ferguson's three factors, as factor analysis will output an abstract factor whether an objectively real factor exists or not. [11] Although replication of the nationalism factor was inconsistent, the finding of religionism and humanitarianism had a number of replications by Ferguson and others. [12] [13]
Shortly afterward, Hans Eysenck began researching political attitudes in the United Kingdom. He believed that there was something essentially similar about the fascism of the National Socialists (Nazis) on the one hand and the communists on the other, despite their opposite positions on the left–right axis. As Hans Eysenck described in his 1956 book Sense and Nonsense in Psychology, [14] Eysenck compiled a list of political statements found in newspapers and political tracts and asked subjects to rate their agreement or disagreement with each. Submitting this value questionnaire to the same process of factor analysis used by Ferguson, Eysenck drew out two factors, which he named "Radicalism" (R-factor) and "Tender-Mindedness" (T-factor).
Such analysis produces a factor whether or not it corresponds to a real-world phenomenon and so caution must be exercised in its interpretation. While Eysenck's R-factor is easily identified as the classical "left–right" dimension, the T-factor (representing a factor drawn at right angles to the R-factor) is less intuitive, as high-scorers favored pacifism, racial equality, religious education and restrictions on abortion, while low-scorers had attitudes more friendly to militarism, harsh punishment, easier divorce laws and companionate marriage.
According to social scientist Bojan Todosijevic, radicalism was defined as positively viewing evolution theory, strikes, welfare state, mixed marriages, student protests, law reform, women's liberation, United Nations, nudist camps, pop-music, modern art, immigration, abolishing private property, and rejection of patriotism. Conservatism was defined as positively viewing white superiority, birching, death penalty, antisemitism, opposition to nationalization of property, and birth control. Tender-mindedness was defined by moral training, inborn conscience, Bible truth, chastity, self-denial, pacifism, anti-discrimination, being against the death penalty and harsh treatment of criminals. Tough-mindedness was defined by compulsory sterilization, euthanasia, easier divorce laws, racism, antisemitism, compulsory military training, wife swapping, casual living, death penalty, and harsh treatment of criminals. [15]
Despite the difference in methodology, location and theory, the results attained by Eysenck and Ferguson matched. Simply rotating Eysenck's two factors 45 degrees renders the same factors of religionism and humanitarianism identified by Ferguson in America. [16]
Eysenck's dimensions of R and T were found by factor analyses of values in Germany and Sweden, [17] France [16] and Japan. [18]
One interesting result Eysenck noted in his 1956 work was that in the United States and the United Kingdom, most of the political variance was subsumed by the left/right axis, while in France the T-axis was larger and in the Middle East the only dimension to be found was the T-axis: "Among mid-Eastern Arabs it has been found that while the tough-minded/tender-minded dimension is still clearly expressed in the relationships observed between different attitudes, there is nothing that corresponds to the radical-conservative continuum". [16]
Eysenck's political views related to his research: Eysenck was an outspoken opponent of what he perceived as the authoritarian abuses of the left and right, and accordingly he believed that with this T axis he had found the link between Nazism and communism. According to Eysenck, members of both ideologies were tough-minded. Central to Eysenck's thesis was the claim that tender-minded ideologies were democratic and friendly to human freedoms, while tough-minded ideologies were aggressive and authoritarian, a claim that is open to political criticism. In this context, Eysenck carried out studies on Nazism and communist groups, claiming to find members of both groups to be more "dominant" and more "aggressive" than control groups. [16]
Eysenck left Nazi Germany to live in Britain and was not shy in attacking Stalinism, citing the antisemitic prejudices of the Russian government, the luxurious lifestyles of the Soviet Union leadership and the Orwellian "doublethink" of East Germany's naming itself the German Democratic Republic despite being "one of the most undemocratic regimes in the world today". [19] While Eysenck was an opponent of Nazism, his relationship with fascist organizations was more complex. Eysenck himself lent theoretical support to the English National Party, which also opposed Hitlerite Nazism, and was interviewed in the first issue of their journal The Beacon in relation to his controversial views on relative intelligence between different races. [20] [21] At one point during the interview, Eysenck was asked whether or not he was of Jewish origin before the interviewer proceeded. [22] His political allegiances were called into question by other researchers, notably Steven Rose, who alleged that his scientific research was used for political purposes. [23] [24]
Eysenck's conception of tough-mindedness has been criticized for a number of reasons.
Dissatisfied with Hans J. Eysenck's work, Milton Rokeach developed his own two-axis model of political values in 1973, basing this on the ideas of freedom and equality, which he described in his book, The Nature of Human Values. [31]
Rokeach claimed that the defining difference between the left and right was that the left stressed the importance of equality more than the right. Despite his criticisms of Eysenck's tough–tender axis, Rokeach also postulated a basic similarity between communism and Nazism, claiming that these groups would not value freedom as greatly as more conventional social democrats, democratic socialists and capitalists would and he wrote that "the two value model presented here most resembles Eysenck's hypothesis". [31]
To test this model, Rokeach and his colleagues used content analysis on works exemplifying Nazism (written by Adolf Hitler), communism (written by Vladimir Lenin), capitalism (by Barry Goldwater) and socialism (written by various authors). This method has been criticized for its reliance on the experimenter's familiarity with the content under analysis and its dependence on the researcher's particular political outlooks.
Multiple raters made frequency counts of sentences containing synonyms for a number of values identified by Rokeach—including freedom and equality—and Rokeach analyzed these results by comparing the relative frequency rankings of all the values for each of the four texts:
Later studies using samples of American ideologues [32] and American presidential inaugural addresses attempted to apply this model. [33]
In further research, [34] Eysenck refined his methodology to include more questions on economic issues. Doing this, he revealed a split in the left–right axis between social policy and economic policy, with a previously undiscovered dimension of socialism-capitalism (S-factor).
While factorially distinct from Eysenck's previous R factor, the S-factor did positively correlate with the R-factor, indicating that a basic left–right or right–left tendency underlies both social values and economic values, although S tapped more into items discussing economic inequality and big business, while R relates more to the treatment of criminals and to sexual issues and military issues.
Most research and political theory since this time has replicated the factors shown above.[ citation needed ]
Another replication came from Ronald Inglehart's research into national opinions based on the World Values Survey, although Inglehart's research described the values of countries rather than individuals or groups of individuals within nations. Inglehart's two-factor solution took the form of Ferguson's original religionism and humanitarianism dimensions; Inglehart labelled them "secularism–traditionalism", which covered issues of tradition and religion, like patriotism, abortion, euthanasia and the importance of obeying the law and authority figures, and "survivalism – self expression", which measured issues like everyday conduct and dress, acceptance of diversity (including foreigners) and innovation and attitudes towards people with specific controversial lifestyles such as homosexuality and vegetarianism, as well as willingness to engage in political activism. See [35] for Inglehart's national chart.
Though not directly related to Eysenck's research, evidence suggests there may be as many as 6 dimensions of political opinions in the United States and 10 dimensions in the United Kingdom. This conclusion was based on two large datasets and uses a Bayesian approach rather than the traditional factor analysis method. [36]
In a 2003 Psychological Bulletin paper, [37] Jeff Greenberg and Eva Jonas posit a model comprising the standard left–right axis and an axis representing ideological rigidity. For Greenberg and Jonas, ideological rigidity has "much in common with the related concepts of dogmatism and authoritarianism" and is characterized by "believing in strong leaders and submission, preferring one's own in-group, ethnocentrism and nationalism, aggression against dissidents, and control with the help of police and military". Greenberg and Jonas posit that high ideological rigidity can be motivated by "particularly strong needs to reduce fear and uncertainty" and is a primary shared characteristic of "people who subscribe to any extreme government or ideology, whether it is right-wing or left-wing".
In its 4 January 2003 issue, The Economist discussed a chart, [35] proposed by Ronald Inglehart and supported by the World Values Survey (associated with the University of Michigan), to plot cultural ideology onto two dimensions. On the y-axis it covered issues of tradition and religion, like patriotism, abortion, euthanasia and the importance of obeying the law and authority figures. At the bottom of the chart is the traditionalist position on issues like these (with loyalty to country and family and respect for life considered important), while at the top is the secular position. The x-axis deals with self-expression, issues like everyday conduct and dress, acceptance of diversity (including foreigners) and innovation, and attitudes towards people with specific controversial lifestyles such as vegetarianism, as well as willingness to engage in political activism. At the right of the chart is the open self-expressionist position, while at the left is its opposite position, which Inglehart calls survivalist. This chart not only has the power to map the values of individuals, but also to compare the values of people in different countries. Placed on this chart, European Union countries in continental Europe come out on the top right, Anglophone countries on the middle right, Latin American countries on the bottom right, African, Middle Eastern and South Asian countries on the bottom left and ex-Communist countries on the top left.
This very distinct two-axis model was created by Jerry Pournelle in 1963 for his doctoral dissertation in political science. The Pournelle chart has liberty on one axis, with those on the left seeking freedom from control or protections for social deviance and those on the right emphasizing state authority or protections for norm enforcement (farthest right being state worship, farthest left being the idea of a state as the "ultimate evil"). The other axis is rationalism, defined here as the belief in planned social progress, with those higher up believing that there are problems with society that can be rationally solved and those lower down skeptical of such approaches.
In 2006, Brian Patrick Mitchell identified four main political traditions in Anglo-American history based on their regard for kratos (defined as the use of force) and archē or "archy" (defined as the recognition of rank). [38] Mitchell grounded the distinction of archy and kratos in the West's historical experience of church and state, crediting the collapse of the Christian consensus on church and state with the appearance of four main divergent traditions in Western political thought:
Mitchell charts these traditions graphically using a vertical axis as a scale of kratos/akrateia and a horizontal axis as a scale of archy/anarchy. He places democratic progressivism in the lower left, plutocratic nationalism in the lower right, republican constitutionalism in the upper right, and libertarian individualism in the upper left. The political left is therefore distinguished by its rejection of archy, while the political right is distinguished by its acceptance of archy. For Mitchell, anarchy is not the absence of government but the rejection of rank. Thus there can be both anti-government anarchists (Mitchell's "libertarian individualists") and pro-government anarchists (Mitchell's "democratic progressives", who favor the use of government force against social hierarchies such as patriarchy). Mitchell also distinguishes between left-wing anarchists and right-wing anarchists, whom Mitchell renames "akratists" for their opposition to the government's use of force.
From the four main political traditions, Mitchell identifies eight distinct political perspectives diverging from a populist center. Four of these perspectives (Progressive, Individualist, Paleoconservative, and Neoconservative) fit squarely within the four traditions; four others (Paleolibertarian, Theoconservative, Communitarian, and Radical) fit between the traditions, being defined by their singular focus on rank or force.
The Nolan Chart was created by libertarian David Nolan. This chart shows what he considers as "economic freedom" (issues like taxation, free trade and free enterprise) on the horizontal axis and what he considers as "personal freedom" (issues like drug legalization, abortion and the draft) on the vertical axis. This puts left-wingers in the left quadrant, libertarians in the top, centrists in the middle, right-wingers in the right and what Nolan originally named populists in the bottom. Several popular online tests, where individuals can self-identify their political values, utilize the same two axes as the Nolan Chart, including The Political Compass, iSideWith.com and MapMyPolitics.org.
The spatial model of voting plots voters and candidates in a multi-dimensional space where each dimension represents a single political issue [39] [40] sub-component of an issue, [a] or candidate attribute. [41] Voters are then modeled as having an "ideal point" in this space and voting for the nearest candidates to that point. The dimensions of this model can also be assigned to non-political properties of the candidates, such as perceived corruption, health, etc. [39]
Most of the other spectra in this article can then be considered projections of this multi-dimensional space onto a smaller number of dimensions. [42] For example, a study of German voters found that at least four dimensions were required to adequately represent all political parties. [42]
In 1998, political author Virginia Postrel, in her book The Future and Its Enemies , offered another single-axis spectrum that measures views of the future, contrasting stasists, who allegedly fear the future and wish to control it, and dynamists, who want the future to unfold naturally and without attempts to plan and control. The distinction corresponds to the utopian versus dystopian spectrum used in some theoretical assessments of liberalism, and the book's title is borrowed from the work of the anti-utopian classic-liberal theorist Karl Popper.
Other proposed axes include:
As shown by Russian political scientist Stepan S. Sulakshin, [49] political spectra can be used as a forecasting tool. Sulakshin offered mathematical evidence that stable development (positive dynamics of the vast number of statistic indices) depends on the width of the political spectrum: if it is too narrow or too wide, stagnation or political disasters will result. Sulakshin also showed that in the short run the political spectrum determines the statistic indices dynamic and not vice versa.
A number of studies have found that biology can be linked with political orientation. [50] Many of the studies linking biology to politics remain controversial and unreplicated, although the overall body of evidence is growing. [51]
Studies have found that subjects with conservative political views have larger amygdalae and are more prone to feeling disgust. [52] [53] Liberals have larger volume of grey matter in the anterior cingulate cortex and are better at detecting errors in recurring patterns. The anterior cingulate cortex is used when dealing with conflicting information. A study conducted by researchers from the University of California, Los Angeles (UCLA) and New York University (NYU) had participants sort through a deck of cards. The letter M was four times more likely to be in the deck than the letter W. Participants had to press a button every time an M came up in the deck. Liberals were shown to make fewer errors in mistaking the W for the M. This behavioral study supported the notion that liberals are better with dealing with conflicting information. [52] [54] Conservatives have a stronger sympathetic nervous system response to threatening images and are more likely to interpret ambiguous facial expressions as threatening. [50] [55] In general, conservatives are more likely to report larger social networks, more happiness and better self-esteem than liberals. Liberals are more likely to report greater emotional distress, relationship dissatisfaction and experiential hardship and are more open to experience and tolerate uncertainty and disorder better. [55] [56] [57]
Genetic factors account for at least some of the variation of political views. [58] [59] From the perspective of evolutionary psychology, conflicts regarding redistribution of wealth may have been common in the ancestral environment and humans may have developed psychological mechanisms for judging their own chances of succeeding in such conflicts. These mechanisms affect political views. [60]
The Political Compass is a website soliciting responses to a set of 62 propositions in order to rate political ideology in a spectrum with two axes: one about economic policy (left–right) and another about social policy (authoritarian–libertarian).
Hans Jürgen Eysenck was a German-born British psychologist. He is best remembered for his work on intelligence and personality, although he worked on other issues in psychology. At the time of his death, Eysenck was the most frequently cited living psychologist in the peer-reviewed scientific journal literature.
The World Values Survey (WVS) is a global research project that explores people's values and beliefs, how they change over time, and what social and political impact they have. Since 1981 a worldwide network of social scientists have conducted representative national surveys as part of WVS in almost 100 countries.
The Nolan Chart is a political spectrum diagram created by American libertarian activist David Nolan in 1969, charting political views along two axes, representing economic freedom and personal freedom. It expands political view analysis beyond the traditional one-dimensional left–right/progressive-conservative divide, positioning libertarianism outside the traditional spectrum.
The left–right political spectrum is a system of classifying political positions, ideologies and parties, with emphasis placed upon issues of social equality and social hierarchy. In addition to positions on the left and on the right, there are centrist and moderate positions, which are not strongly aligned with either end of the spectrum. It originated during the French Revolution based on the seating in the French National Assembly.
In psychology, trait theory is an approach to the study of human personality. Trait theorists are primarily interested in the measurement of traits, which can be defined as habitual patterns of behavior, thought, and emotion. According to this perspective, traits are aspects of personality that are relatively stable over time, differ across individuals, are relatively consistent over situations, and influence behaviour. Traits are in contrast to states, which are more transitory dispositions.
The Pournelle chart, developed by Jerry Pournelle in his 1963 political science Ph.D. dissertation, is a two-dimensional coordinate system which can be used to distinguish political ideologies. It is similar to the political compass and the Nolan Chart in that it is a two-dimensional chart, but the axes of the Pournelle chart are different from those of other systems. The two axes are as follows:
In sociology, postmaterialism is the transformation of individual values from materialist, physical, and economic to new individual values of autonomy and self-expression.
The authoritarian personality is a personality type characterized by a disposition to treat authority figures with unquestioning obedience and respect. Conceptually, the term authoritarian personality originated from the writings of Erich Fromm, and usually is applied to people who exhibit a strict and oppressive personality towards their subordinates. Regardless of whether authoritarianism is more of a personality, attitude, ideology or disposition, scholars find it has significant influence on public opinion and political behavior.
Social dominance orientation (SDO) is a personality trait measuring an individual's support for social hierarchy and the extent to which they desire their in-group be superior to out-groups. SDO is conceptualized under social dominance theory as a measure of individual differences in levels of group-based discrimination; that is, it is a measure of an individual's preference for hierarchy within any social system and the domination over lower-status groups. It is a predisposition toward anti-egalitarianism within and between groups.
In psychology, right-wing authoritarianism (RWA) is a set of attitudes, describing somebody who is highly submissive to their authority figures, acts aggressively in the name of said authorities, and is conformist in thought and behavior. The prevalence of this attitude in a population varies from culture to culture, as a person's upbringing and education play a strong role in determining whether somebody develops this sort of worldview.
The Authoritarian Personality is a 1950 sociology book by Theodor W. Adorno, Else Frenkel-Brunswik, Daniel Levinson, and Nevitt Sanford, researchers working at the University of California, Berkeley, during and shortly after World War II.
In political science and sociology, a cleavage is a historically determined social or cultural line which divides citizens within a society into groups with differing political interests, resulting in political conflict among these groups. Social or cultural cleavages thus become political cleavages once they get politicized as such. Cleavage theory accordingly argues that political cleavages predominantly determine a country's party system as well as the individual voting behavior of citizens, dividing them into voting blocs. These blocs are distinguished by similar socio-economic characteristics, who vote and view the world in a similar way. It is distinct from other common political theories on voting behavior in the sense that it focuses on aggregate and structural patterns instead of individual voting behaviors.
The Rokeach Value Survey (RVS) is a values classification instrument. Developed by social psychologist Milton Rokeach, the instrument is designed for rank-order scaling of 36 values, including 18 terminal and 18 instrumental values. The task for participants in the survey is to arrange the 18 terminal values, followed by the 18 instrumental values, into an order "of importance to YOU, as guiding principles in YOUR life".
In popular discourse, the horseshoe theory asserts that advocates of the far-left and the far-right, rather than being at opposite and opposing ends of a linear continuum of the political spectrum, closely resemble each other, analogous to the way that the opposite ends of a horseshoe are close together. The theory is attributed to the French philosopher and writer of fiction and poetry Jean-Pierre Faye in his 1972 book Théorie du récit: introduction aux langages totalitaires, in relation to Otto Strasser.
Self-expression values are part of a core value dimension in the modernization process. Self-expression is a cluster of values that include social tolerance, life satisfaction, public expression and an aspiration to liberty. Ronald Inglehart, the University of Michigan professor who developed the theory of post-materialism, has worked extensively with this concept. The Inglehart–Welzel Cultural Map contrasts self-expression values with survival values, illustrating the changes in values across countries and generations. The idea that the world is moving towards self-expression values was discussed at length in an article in the Economist. Expressing one's personality, emotions, or ideas through art, music, or drama, is a way to reveal oneself to others in a way that is special to them.
Brian Patrick Mitchell is an American writer, political theorist, and blogger, known for his theory of political difference, theology of interpersonal relations, and critical analysis of gender integration of the American armed forces.
Hofstede's cultural dimensions theory is a framework for cross-cultural psychology, developed by Geert Hofstede. It shows the effects of a society's culture on the values of its members, and how these values relate to behavior, using a structure derived from factor analysis.
The Inglehart–Welzel cultural map of the world is a scatter plot created by political scientists Ronald Inglehart and Christian Welzel based on the World Values Survey and European Values Survey. It depicts closely linked cultural values that vary between societies in two predominant dimensions: traditional versus secular-rational values on the vertical y-axis and survival versus self-expression values on the horizontal x-axis. Moving upward on this map reflects the shift from traditional values to secular-rational ones and moving rightward reflects the shift from survival values to self-expression values.
In political science and social choice theory, the spatialmodel of voting, also known as the Hotelling–Downs model, is a mathematical model of voting behavior. It describes voters and candidates as varying along one or more axes, where each axis represents an attribute of the candidate that voters care about. Voters are modeled as having an ideal point in this space and preferring candidates closer to this point over those who are further away; these kinds of preferences are called single-peaked.
France invented the terms Left and Right early in the great Revolution of 1789– 94 which first limited the powers of, and then overthrew, the Bourbon monarchy.[ dead link ]
Since our model is multi-dimensional, we can incorporate all criteria which we normally associate with a citizen's voting decision process — issues, style, partisan identification, and the like.
The spatial model of voting is the work horse for theories and empirical models in many fields of political science research, such as the equilibrium analysis in mass elections ... the estimation of legislators' ideal points ... and the study of voting behavior. ... Its generalization to the multidimensional policy space, the Weighted Euclidean Distance (WED) model ... forms the stable theoretical foundation upon which nearly all present variations, extensions, and applications of multidimensional spatial voting rest.
Assume that voters care about the "attributes" of candidates. These attributes form a multi-dimensional "attribute space."
The analysis reveals that the underlying political landscapes ... are inherently multidimensional and cannot be reduced to a single left-right dimension, or even to a two-dimensional space. ... From this representation, lower-dimensional projections can be considered which help with the visualization of the political space as resulting from an aggregation of voters' preferences. ... Even though the method aims to obtain a representation with as few dimensions as possible, we still obtain representations with four dimensions or more.
