    Procedural Perceptions and Support for the U.S.

    Supreme Court

    Mark D. Ramirez

    This paper examines public support toward the U.S. Supreme Court. Although previous

    scholars have rightly focused on policy outcomes in explaining public attitudes toward the

    Court, outcome-based theories are unable to explain why support for the Court remains

    high despite public disagreement with Court decisions. Some scholars argue the low

    visibility of the Court shields it from public scrutiny. The exposure explanation, however, is

    inconsistent with the empirical finding that to know the Court is to love it. This paper

    reconciles these differences by showing how media coverage of the Court can influence

    procedural perceptions and subsequent support for the Court. Expanding on recent studies

    examining media coverage of the Court and perceptions of fairness, this study examineshow procedural perceptions mediate support for the Court. An experimental design shows

    that the medias portrayal of procedural information as either fair or unfair influences

    public evaluations of procedural fairness and subsequently support for the Court as an

    institution and the individual justices serving on the Courts bench.

    KEY WORDS: procedural justice, Supreme Court, public opinion, political support

    Democratic government relies on the support of the public. Although all

    political institutions need some public support, public approval of the judiciary,

    particularly the U.S. Supreme Court, is especially important. As frequently noted,the Supreme Court does not possess the budgetary power of Congress or the

    enforcement power of the President. Instead, low levels of support may reduce

    compliance with court decisions (Murphy & Tanenhaus, 1968; Tyler & Rasinski,

    1991). Despite the importance of maintaining high levels of public esteem,

    the U.S. Supreme Court is not immune from controversy. The Court makes

    controversial rulings on important public policy issues ranging from abortion

    to affirmative action to school prayer. The nominations of its members are also

    highly visible and politicized and controversial events surrounding the Court.

    Nevertheless, the Supreme Court is able to maintain the support of the American

    public in the face of controversy (e.g., Caldeira & Gibson, 1992; Hibbing &

    Theiss-Morse, 1995; Mondak & Smithey, 1997).

    An extensive literature examines public support for the Supreme Court.

    Scholars have offered numerous theories explaining public esteem for the Court,

    including a commitment to basic democratic values (Caldeira & Gibson, 1992)

    and a mystique of legality surrounding the Court that predisposes citizens to view

    controversies surrounding the Court in a matter that does not threaten the legiti-

    macy of the institution (Casey, 1974; Gibson, Caldeira, & Spence, 2003; Scheb &

    Lyons, 2000).

    Other scholarship shows the immediate actions of the Court can weaken its

    contemporaneous levels of public support (e.g., Caldeira, 1986; Franklin &

    Kosaki, 1989; Hoekstra, 2003). Grosskopf and Mondak (1998) found individuals

    disagreeing with two highly visible Supreme Court decisions (Webster v. Repro-

    ductive Health Services and Texas v. Johnson) were less likely to have confi-

    dence in the Court relative to individuals agreeing with both of the decisions.

    Agreement with the decisions, however, failed to increase levels of individual

    confidence in the Supreme Court. Although the Court may lose support with

    unfavorable decisions, it appears unable to generate support with favorable

    decisions. If unpopular decisions only hurt public support for the Supreme

    Court, how does the Court maintain high levels of public approval? What keeps

    support for the Court from taking a downward spiral upon successive unpopular

    decisions?

    One explanation is that media coverage of the Court is devoid of political

    conflict and bargaining that permeates coverage of other institutions (Hibbing &

    Theiss-Morse, 1995). This implies the Supreme Courts secret deliberations, infre-

    quent media coverage, and low levels of visible conflict sustain the high levels of

    support for the Court because citizens remain unaware of the debate and politi-

    cizing within the Court. Therefore, exposure to Court proceedings should decrease

    support for the Court. This explanation, however, contrasts with well-known

    scholarship that citizens who are more attentive to the activities of the Supreme

    Court hold the Court in higher regard in comparison to their inattentive peers

    (Adamany & Grossman, 1983; Casey, 1974; Kessel, 1966; Scheb & Lyons, 2000).

    This paper argues public support for the Court is not simply a function of the

    visibility of Court proceedings, but a function of how information about the Court

    is portrayed in the media. In other words, it is the type of information rather than

    the volume of information that is important in how the public perceives the Court.

    Information that reinforces the legal image of the Court should sustain favorable

    attitudes, while information that portrays the Courts decision-making process as

    unfair should lead to less favorable opinions. Specifically, media framing of Court

    proceedings as fair or unfair should influence perceptions of procedural justice,

    Media Framing, Procedural Perceptions, and Support

    The extent and limitations of media framing are becoming widely known

    in political science and are being applied to various political domains (e.g.,

    Druckman, 2004; Iyengar & Kinder, 1987; Nelson, Clawson, & Oxley, 1997).

    How the media portrays political debates and government proceedings affects

    public opinion by making some considerations more important than others

    (Nelson, Clawson, & Oxley, 1997).

    Several important pieces of research show a connection between media cov-

    erage of the Court and perceptions of the Court. Nicholson and Howard (2003)

    expand the framing literature to show that framing of political institutions and

    actors can shape public support toward those attitude objects. They find that

    framing the Courts Bush v. Gore decision as a partisan decision reduces the

    confidence in justices by activating individuals partisanship and disagreement

    with the decision, while framing the decision as an electoral concern decreases the

    Courts diffuse or long-term support. Media coverage of the Court has also been

    shown to alter perceptions of procedural fairness regarding the Court (Baird &

    Gangl, 2006). These authors show experimental subjects had higher perceptions of

    procedural fairness when presented with a media story portraying the Court in a

    legalistic rather than political frame.

    Although this previous work is important, it is still unclear if procedural

    perceptions mediate support for the Supreme Court. Why should procedural per-

    ceptions be important in how citizens think about political institutions such as the

    Supreme Court? Procedural justice theory shows that the procedural components

    citizens use in evaluating decision-making organizations are perceptions of citizen

    representation, neutrality of the process, and belief in the trustworthiness of

    the individual decision makers within an organization (e.g., Gangl, 2003; Tyler,

    1988). Although Tylers research is focused on actual litigants experiences, there

    is no reason why the theory should not apply to third-party observers of the Court.

    Citizens want to believe they have a voice in the decision-making process of

    organizations that can potentially shape their personal affairs. Although individu-

    als do not have the opportunity to communicate their opinion directly to the

    Supreme Court, it is important they are able to identify with individuals involved

    in the decision-making process who symbolize their interests. Furthermore, the

    process is expected to be neutral. It is important that the institutional structure,

    norms, and rules ensure no single point of view dominates the decision-making

    process. Finally, citizens need to trust the individual members serving on the

    Court. People expect Court justices to derive their decisions from legal precedent

    instead of political or personal interests. Individuals presume the Court justices to

    be neutral interpreters of the law and Constitution. They should not be influenced

    by political or special interest group pressure or decide cases according to their

    challenged, the Supreme Court should be able to sustain high levels of public

    support. If citizens receive information portraying the Supreme Court as proce-

    durally unfair, however, support for the Court should decline.

    Procedural justice theory provides a solution to the puzzle between expo-

    sure and support for the Supreme Court. Hibbing and Theiss-Morse (1995)

    assume greater exposure to the Courts decision-making process will increase

    perceptions of procedural conflict and inherent biases within the Court. Although

    citizens dislike the conflict associated with political bargaining (Hibbing &

    Theiss-Morse, 2002), perceptions of procedural fairness of the Court are related

    to perceptions of legality rather than mere bargaining and deliberation (Baird &

    Gangl, 2006). Media coverage of the Court tends to focus on legitimizing

    symbols (Gibson, Caldeira, & Spence, 2003) and legal jargon (Slotnick & Segal,

    1998). One recent theory accounting for the stability of support for the Court is

    that the Court experiences a positivity bias where the most prevalent infor-

    mation about the Court is framed in symbols and language that promote the

    legality and procedural fairness of the Court (Gibson, Caldeira, & Spence,

    2003). These legal symbols perpetuate the perception of objectivity and neutral-

    ity surrounding the Court, sustaining positive procedural perceptions among the

    public and subsequently the institutions support. In addition to the publics

    support for democratic principles, these positive procedural frames should con-

    tribute in sustaining the publics positive perceptions of the Court. Conversely,

    when citizens receive information about the Congress or executive branch, it

    typically concerns partisan debate and procedural conflict. Therefore, it is not

    exposure per se that influences evaluations toward the Court, but how the por-

    trayal of the Courts decision-making process influences procedural perceptions

    that shapes how citizens evaluate the Court. When the media portrays the Court

    as procedurally fair, support for the Court should be higher relative to when the

    media portrays the Court as procedurally unfair because media frames alter per-

    ceptions of procedural justice.

    Research Design

    A 2 2 between groups experimental design is employed to test the preceding

    hypotheses. The experimental factors are the portrayal of procedural justice as

    either fair or unfair and issue domain (criminal justice or economic policy). The

    design also includes a nonexperimental factorwhether or not a subjects policy

    predisposition is congruent with the policy outcome of the Courts decision.

    The study was conducted in the Spring of 2005 at a large research university in

    Texas.Two hundred and sixty-one undergraduate students participated in the study.1

    for research and development costs from the U.S. government. The Court decided

    against Boeing, making headlines primarily in business and trade publications.

    Neither of the Court rulings are misrepresented in the vignettes nor are the

    outcomes manipulated within experimental conditions.

    Opinion-policy congruence. Prior to their exposure to the experimental stimu-

    lus, participants answered a series of questions concerning their policy preferences

    on several political issues in addition to basic political questions ranging from

    partisanship to political interest. Subjects were asked: Some say a law called

    three strikes and youre out, which requires that anyone convicted of three

    felonies to be automatically sentenced to life in prison without parole, targets

    career criminals. Others claim the law is too severe for minor felonies like petty

    theft. In general, do you favor or oppose this law, or havent you thought about it

    much? and Some people believe the U.S. government should provide private

    U.S. companies with export subsidies to help them support private competition.

    Other people believe the U.S. government should not support private companies

    with tax revenue. In general, do you favor or oppose export subsidies, or havent

    you thought about it much? The questions attempt to match the specific cases in

    the vignettes; however, there is some discrepancy between the deterministic three-

    strikes law in the opinion measure and the discretion of the justices of upholding

    the sentence presented in the vignettes.3

    I assume the Courts decision in the case is congruent with each subjects

    predisposition if the subjects prestimulus response to the relevant policy prefer-

    ence measure is in the same direction as the Courts decision. A policy predispo-

    sition in the opposite direction of the policy outcome in the vignette is assumed to

    be incongruent with the Courts decision. This measurement scheme is consistent

    with the opinion-policy congruence measures in the representation literature

    (Miller & Stokes, 1963; Monroe, 1983; Weissberg, 1976), but also subject to the

    same limitations as these measures (Achen, 1977; Stone, 1979).

    Support for a specific policy position does not automatically mean the subject

    agrees or disagrees with the Courts decision. The Court may be able to persuade

    the public into changing their views (Dahl, 1957; Hoekstra, 1995), although

    Caldeira (1991) notes, [W]e have relatively few well-documented instances when

    the Supreme Court has shaped the aggregate distribution of public support for this

    or that policy (p. 312). Alternatively, scholarship suggests Court decisions crys-

    talize existing attitudes (Brickman & Peterson, 2006; Franklin & Kosaki, 1989;

    Johnson & Martin, 1998), suggesting participants would become even more sup-

    portive of their policy positions after reading the experimental vignettes. However,

    measurement of posttreatment policy preferences or agreement with the Courts

    decision were not included in the survey instrument, limiting the ability to make

    any firm conclusions about participants postexperiment policy attitudes.

    680 Ramirez

    Posttreatment agreement with the Courts decision was not utilized in this

    experiment since the content of the manipulation might bias responses to the policy

    preference measures. The prestimulus measure also prevents opinions from being

    influenced by the legitimizing function of the Court. The purpose of this study is

    not to determine the Courts power to persuade the public to accept unfavorable

    decisions, but to determine the relationship between perceptions of procedural

    justice and support toward the Court, independent of policy preferences.

    Furthermore, the outcomes of the cases are not experimentally manipulated.

    For instance, the Court upheld the three-strikes law in all of the crime vignettes

    and opposed Boeings claim that the company was entitled to export subsidies

    from the government in all of the economic subsidies vignettes. Therefore, all

    participants supporting the three-strikes law prior to reading the Courts decision

    are assumed to have a predisposition congruent with the Courts ruling. All

    participants opposing the three-strikes law are coded as having a predisposition

    incongruent with the Courts decision. The congruence or incongruence of each

    participants predisposition with the outcome of the export subsidies case are

    determined in the same manner.

    The response options to the policy questions are on a 4-point ordinal scale

    ranging from favor to oppose with a dont know response option.4 Within

    the three-strikes vignette 45% of the participants have a policy predisposition in

    the same direction as the Courts ruling, and 54% of participants have a policy

    predisposition incongruent with the Courts decision. Within the economic subsi-

    dies vignette 44% of participants have a policy predisposition congruent with the

    Courts decision, and 55% of participants have a policy predisposition incongruent

    with the Courts decision.

    Procedural justice treatment. The procedural justice variable is manipulated

    by altering how the Court proceedings are depicted in the fictitious newspaper

    article. Half of the participants read an article where the vignette portrays the

    Supreme Courts procedures as being fair. The other half read articles where the

    vignette portrays the Supreme Courts procedures as unfair.

    In the fair or baseline condition, the vignette describes the Supreme Courts

    processes as objective, trustworthy, and inclusive. Comments from spokespersons

    on each side of the debate are provided indicating each had an equal and influential

    voice prior to the Supreme Courts decision. Unidentified eyewitnesses report the

    justices listened carefully to arguments on both sides of the debate before retiring

    to their chambers to deliberate on the pros and cons of each argument. Court

    commentators emphasize their satisfaction with procedural aspects of the decision.

    Finally, the vignettes highlight the Supreme Courts objectivity and ability to use

    legal precedent and principles instead of being politically motivated in formulating

    their decision.

    Participants in the unfair condition read vignettes describing the Court as

    untrustworthy, unrepresentative, and biased. These are the three procedural dimen-

    sions indicated by Tyler (1988) to be important in how individuals evaluate

    decision-making organizations. The lack of representation of the Court is manipu-

    lated by mentioning that the Supreme Court makes its decisions without jury

    deliberations and its justices are not elected by the public. The trustworthiness

    of the Court justices is called into question when the article mentions one justices

    interaction with special interest groups associated with the case and vote switching

    by another justice. Finally, the objectivity or legal image of the Court is challenged

    by Court commentators tired of seeing the U.S. Supreme Court becoming politi-

    cally involved in this issue.5

    The contents from the unfair vignettes are an adaptation and amalgamation of

    actual published accounts of the procedural activities of the Court (Biskupic, 1997;

    Lazarus, 1998; Lane, 2004), but are not associated with the cases described above.

    Although actual reporting of Court procedures is not as extreme as depicted in

    the vignettes (but see Cannon, 2004; Lane, 2006a; Lane, 2006b), the purpose of

    the experimental design is to provide a counterfactual of what if citizens were

    exposed to heavy-handed procedural information about the Court. The ability of

    experimental designs to test counterfactuals or unrealistic occurrences should be

    viewed as a virtue instead of a vice (Lavine, Lodge, Polichak, & Taber, 2002;

    Mook, 1983).6

    In the posttreatment questionnaire, respondents were asked three questions

    regarding their perceptions of procedural justice in the Courts decision-making

    process. The three indicators attempt to capture the aforementioned dimensions of

    procedural justice (representation, objectivity, and trustworthiness). Measures of

    participant perceptions of representation in the Supreme Courts decision are

    measured by asking participants, To what extent or amount do you think people

    who share your views were given a say in the decision-making process in the

    Supreme Court case mentioned above? Responses range on a 5-point scale from

    a Great Amount to None at All. Perceptions of the objectivity of the Supreme

    Court are measured by asking participants, On the whole, how accurate do you

    think it is to say that no one interest or point of view seemed to have more input

    and consideration than others in producing the Courts decision? with responses

    ranging on a 5-point scale from Very Accurate to Very Inaccurate. Participant

    perceptions of the honesty of the individual justices are measured by asking

    participants, On the whole, how trustworthy do you think the Supreme Court

    5 The unfair vignettes also make reference to the procedural conflict around the votes of the justicespresenting a potential confound to this designan issue taken up in the anlaysis below.

    6 The manipulations might lead some to correctly argue the results are not generalizable, however,li bili i i f f h d I i hi h b hi d

    Justices intentions were in coming to their decision? with responses ranging on

    a 5-point scale from Very Trustworthy to Very Untrustworthy.

    A confirmatory factor analysis demonstrates these individual measures load

    on a single dimension of procedural justice.7 These indicators are combined into a

    procedural justice variable ranging from one to five with higher values indicating

    greater perceptions of procedural justice. Cronbachs alpha (.6) shows the proce-

    dural justice index is moderately reliable.

    Dependent variable. Traditionally, scholars of the Court have differentiated

    between specific and diffuse support (e.g., Easton, 1965; Caldeira & Gibson,

    1992). Research also indicates individuals are able to distinguish between political

    institutions and the individual members within those institutions (Hibbing &

    Theiss-Morse, 1995). Specific support involves attitudes toward the immediate

    justices and policy outcomes of the Court and diffuse support involves attitudes

    toward the Court as an institution. Previous research shows specific actions or

    outcomes of the Court do not influence diffuse support (Caldeira & Gibson, 1992),

    but rather influence specific support (Caldeira, 1986). The latter distinction is

    important because it means having a policy preference incongruent with a specific

    Court ruling might create discontent toward individual justices, but citizens will

    nevertheless continue to adhere to the Courts legitimacy. It is possible perceptions

    of procedural justice affect attitudes toward the justices and not the Court as an

    institution, the reverse, or both.

    The dependent variable consists of two indicators of support toward the U.S.

    Supreme Court. The first indicator asks participants to rate the Supreme Court as an

    institution reading, thinking of the Supreme Court as an institution, do you approve

    strongly, approve somewhat, neither approve nor disapprove, disapprove some-

    what, or disapprove strongly of the Supreme Court, no matter who the Justices are?

    The second question asks participants their attitude toward the individual justices

    currently serving on the Supreme Court. Thinking about the people on the Supreme

    Court, please tell me if you approve strongly, approve somewhat, neither approve

    nor disapprove, disapprove somewhat, or disapprove strongly of the way the nine

    justices on the Supreme Court are handling their job? These measures are adapted

    from previous research on public support for political institutions (Hibbing &

    Theiss-Morse, 1995; Hoekstra, 2003). Each 5-point scale is reflected in the analysis

    where higher scores indicate greater levels of support toward the political object

    being analyzed. The ordering of these questions is randomly reversed to prevent any

    systematic biases in the responses. A difference of means test shows participants

    differentiate between evaluations toward the Supreme Court as an institution and the

    Supreme Court justices. Support for the institution, M= 3.9, is higher than support

    for the members of the Supreme Court,M= 3.4, (t= 8.1,p < .001). The correlation

    indicators measure distinct concepts.

    Manipulation check. The procedural justice index provides a means to

    observe whether participants in the fair procedural condition perceived the

    Supreme Court as being more procedurally representative, objective, and trust-

    worthy than participants in the procedurally unfair condition. The results indicate

    clear differences between groups receiving procedurally fair versus procedurally

    unfair treatments.

    Perceptions of procedural justice are higher for participants receiving a

    procedurally fair three-strikes vignette, M= 3.80 .06, than participants receiv-

    ing the procedurally unfair three-strikes vignette, M= 3.08 .07 (t= 6.87,

    p < .001). Perceptions of procedural justice are also higher for participants

    receiving a procedurally fair export subsidies vignette, M= 3.72 .06, than

    participants receiving the procedurally unfair export subsidies vignette,

    M= 2.90 .08 (t= 7.64, p < .001). In addition, the issue domain does not make

    a difference in procedural justice evaluations. Perceptions of procedural justice

    are not statistically different for participants receiving the crime vignette,

    M= 3.4 .06, relative to participants receiving the economic subsidies vignette,

    M= 3.3 .06 (t= 1.2, p < .2). These data support the internal validity of the

    experimental design.

    Additional analysis shows there is no difference between Republicans and

    Democrats in their perceptions of procedural justice within the procedurally fair

    and unfair conditions. Democrats in the three-strikes condition do have higher

    levels of procedural justice perceptions, M= 3.6, than Republicans in the crime

    condition, M= 3.4, t(1, 102) = 1.50, p < .07. Although we might expect Demo-

    crats to view this issue as more important than Republicans, subsequent testing

    did not show perceptions of issue importance influencing procedural justice

    perceptions among Democrats in the three-strikes condition. More important,

    analysis not reported here shows this difference did not lead to any substantial

    differences in the main variable of interestsupport for the Court.

    Results

    There are several estimators available for analyzing the data. First, I use an

    ANOVA to show differences in levels of support for groups assigned to different

    conditions. The results demonstrate participants receiving an unfair portrayal of

    the Court have less support than participants receiving a fair portrayal of the Court.

    Next, a path analysis shows levels of support for the Court differ because the fair

    and unfair conditions lead to differences in perceptions of procedural justice.

    Finally, an ordered probit analysis shows differences in levels of support for

    individuals, while also generating predicted probabilities for substantively inter-

    increase the clarity of the presentation. When the results do differ between issue

    domains, these differences are shown.8

    A 2 2 between groups ANOVA yielded a significant main effect for both the

    procedural condition and opinion-policy congruence with the Courts decision.

    Participants in the fair condition have more support for the institution of the

    Supreme Court, M= 4.07, than participants in the unfair condition, M= 3.78,

    F(1, 225) = 7.85, p < .001, while participants with a predisposition congruent with

    the Courts decision have higher levels of support for the institution, M= 4.02,

    than participants whose predisposition is incongruent with the Courts decision,

    M= 3.83, F(1, 225) = 3.40, p < .06. There are no differences in support for

    the Court as an institution when the three-strikes and economic conditions are

    analyzed separately. The interaction between participants in the procedural con-

    dition and opinion-policy congruence is also statistically insignificant.

    I also compared the level of support for the Court as an institution among

    participants that chose the dont know response option to the policy preference

    question. The mean level of support for the Court as an institution between

    subjects choosing the dont know response opinion, M = 3.89, and subjects with

    a policy predisposition incongruent with the Courts decision is statistically indis-

    tinguishable, M = 3.83, t(1, 154) = 0.36, p < 0.35. The mean level of support for

    the Court as an institution between subjects that dont know their policy pref-

    erence, M = 3.89, is also statistically equivalent to subjects with a policy predis-

    position congruent with the Courts decision, M = 4.02, t(1, 131) = 0.94, p < 0.82.

    A separate 2 2 between groups ANOVA also shows a significant main effect

    for each factor on support for the Court justices. Participants in the procedurally

    fair condition are more supportive of the Court justices,M= 3.67, than participants

    in the procedurally unfair condition, M= 3.18, F(1, 225) = 14.88, p < .001.

    Having a policy predisposition congruent with the Courts decision also leads to

    higher levels of support for the Court justices, M= 3.51, relative to participants

    with a policy predisposition incongruent with the Courts decision, M= 3.28,

    F(1, 225) = 4.82, p < .001. Participants in the procedurally fair condition who have

    a policy predisposition congruent with the Courts decision exhibit marginally

    step with the Courts decision, rather than congruent with the decision. The latter

    results suggest that even when the publics preferences are incongruent with the

    immediate actions of the Court, positive information regarding the Court (i.e., fair

    portrayal) can sustain the Courts support.

    Support for the justices among participants choosing the dont know option

    to the relevant policy preference question show participants choosing dont

    know, M = 3.6, have higher levels of support for the justices currently serving

    on the Court than subjects with a policy predisposition incongruent with the

    Courts decision, M = 3.2, t(1, 154) = 2.17, p < 0.01. None of the other compari-

    sons with dont know participants are statistically significant. Analysis of

    support for the justices within each issue condition indicates participants in the

    crime condition with policy preferences incongruent with the Courts decision

    have lower levels of support for the justices, M = 3.0, compared to subjects in

    the economic condition with policy preferences incongruent with the Courts

    decision, M = 3.5, t(1, 126) = 3.08, p < .01. It seems support for the Justices is

    more sensitive to the issue domain than evaluations of the institution, but no other

    important difference across issue domains are observed in these data.

    Path Analysis

    The previous results demonstrate support for the Court is higher when

    participants receive procedural fair rather than unfair information regarding the

    Courts decision-making process. Furthermore, this relationship holds when

    controlling for the congruence of the participants policy predisposition with the

    Courts ruling. The results, however, fail to demonstrate the precise mechanism

    that mediates support for the Court. If the procedural theory is correct, support for

    the Court is not a function of simply being exposed to a procedural fair or unfair

    account of a Court case (e.g., media framing effects). Instead, the theory argues it

    is how those portrayals alter perceptions of procedural justice regarding the

    Courts decision-making process that influences Court approval. Therefore,

    perceptions of procedural justice should have a positive and significant relation-

    ship with support for the Court independent of the procedural condition and

    opinion-policy congruence.

    Estimating the influence of procedural justice perceptions while controlling

    for the procedural justice condition also controls for the length of the vignettes and

    potential confounds within the vignettes. The unfair condition contains more

    information than the fair condition. To ensure it is not the amount of information

    but the type of information that influences Court approval, the following models

    estimate the influence on procedural justice perceptions on support for the Court

    while controlling for the procedural condition.

    A path analysis can also help control for other potential confounds in

    686 Ramirez

  • 8/8/2019 Procedural Perceptions and Support for the U.S. Supreme Court

    13/25

    procedural justice or because of potential confounds in the vignettes. If something

    about the issue portrayed in the vignettes is shaping support, then opinion-policy

    congruence should measure some of this effect. Even more important, controlling

    for procedural condition (fair vs. unfair) should account for any other systematic

    factor within the vignettes that are influencing support for the Court, independent

    of procedural justice. The path analysis shows subjects in the fair or unfair

    conditions have different levels of support because of differences in their percep-

    tions of procedural justice and not because of anything else inherent in the

    conditions since there is no main or direct effect of procedural condition on

    support.

    For ease of presentation, a single path analysis is estimated for support for the

    Supreme Court as an institution and for the members on the Courts bench.9

    Perceptions of procedural justice are measured using the procedural justice index

    where higher values indicate a greater perception of procedural justice. In addition,

    a new opinion-policy congruence variable is created that uses the complete

    responses to each participants policy predisposition question where 1 = oppose,

    2 = somewhat oppose, 3 = somewhat favor, and 4 = favor. The variable is

    coded where higher values indicate a predisposition more consistent with the

    Supreme Courts ruling.

    Figure 1 shows standardized regression coefficients for the path analysis

    for support for the Supreme Court. Solid lines indicate statistically significant

    coefficients. A standardized regression coefficient of .80 between the procedural

    condition and perceptions of procedural justice confirms that exposure to a pro-

    cedurally fair vignette increases positive perceptions of procedural justice. Further,

    the results fail to show a relationship between opinion-policy congruence and

    perceptions of procedural justice. This suggests that perceptions of procedural

    justice were not influenced by participants policy predisposition. Other studies do

    find agreement with the Courts decision does influence perceptions of procedural

    fairness (Baird & Gangl, 2006; Gibson, Caldeira, & Spence, 2003). However,

    these studies dealt with a case on civil liberties and the 2000 presidential election,

    respectively, that should be more important to respondents than the cases selected

    here. It is possible that cases more important to the public may result in policy

    preferences having a larger influence on how they perceive procedural aspects of

    the Court.

    However, there is evidence that more visible cases might not alter the effect of

    the Courts policy decisions on support for the Court. Gibson, Caldeira, and

    Spence (2003) find views of the outcome of the election [Bush v. Gore] influence

    judgements of decisional fairness, but have little impact on institutional loyalty

    (p. 549). These authors also add that support is insulated from contemporary

    events. Given the high profile of this Supreme Court case in their study, their

    687Procedural Perceptions and Support for the U.S. Supreme Court

    research provides stronger evidence that the relationship between policy and

    support would be similar to the findings in these data even if the cases were of

    higher importance. When scholars have found Court decisions influencing support

    for the Court, it has been among subgroups who we might believe are more

    affected by the outcomes of the case (Hoekstra, 2003).

    The standardized regression coefficient between perceptions of procedural

    justice and support for the Court is .22, demonstrating support for the Court

    increases as perceptions of procedural justice increase. Furthermore, the proce-

    dural condition variable does not have a direct effect on support when controlling

    for perceptions of procedural justice, providing evidence the amount of informa-

    tion or any potential confounds within the vignettes are not shaping support for the

    Court. Differences in support for the Supreme Court among individuals are not

    because the participant was simply included in the procedurally unfair or fair

    condition. Inclusion in the procedurally fair or unfair condition shapes support for

    the Supreme Court because it creates differences in perceptions of procedural

    justice. Finally, the standardized coefficient of .12 between opinion-policy con-

    The path analysis shows subjects in the fair or unfair conditions have different

    levels of support because of differences in their perceptions of procedural justice

    and not because of anything else inherent in the conditions. There is no direct

    effect of procedural condition on support. Instead, the effect is mediated through

    procedural justice perceptions. If there was something else within the vignettes not

    accounted for by procedural justice perceptions that was systematically influenc-

    ing the Court, we would expect the procedural condition variable to influence

    support directly. It does not.

    Substantive Interpretations

    The predicted probabilities of the different levels of support for the Court is

    estimated using Clarify (King, Tomz, & Wittenberg, 2001). Table 1 shows the

    results of an ordered probit analysis with the same specification as the path

    analysis models for support for both the Court as an institution and the Court

    justices. Wald tests for parameter equivalency suggest no difference between

    models of support within participants in the crime and economic conditions. Both

    perceptions of procedural justice and opinion-policy congruence are statistically

    significant in both models. The ordered probit analysis is used to simulate

    predicted probabilities of support for the Court. Of particular interest is the

    relationship between procedural justice and support when the participant agrees

    with the Courts ruling. A policy predisposition congruent with the Courts ruling

    should sustain positive support for the Court. The theory suggests, however,

    support for the Court will decrease when perceptions of procedural justice

    decrease, despite a participant having a predisposition congruent with the Courts

    substantive decision. Holding the opinion-policy congruence variable constant at

    its maximum value, the procedural justice variable is changed from its maximum

    to its minimum value. Additionally, the procedural condition variable is held at 0

    to simulate what happens when people receive an unfavorable account of a

    Supreme Court case.

    The results in Table 2 show that the predicted probability of strongly approv-

    ing of the Supreme Court as an institution decreases by .28 when procedural

    justice perceptions shift from their maximum to minimum values. It appears

    participants were unwilling to completely disapprove of the Court as an institution,

    but negative perceptions of procedural justice do lead individuals to gravitate

    toward a more moderate position on the scale by .22 rather than the typical high

    levels of support awarded to the Court. Additionally, these changes occur when the

    participants policy predisposition is congruent with the Courts decision. When

    the procedural justice index is moved from its maximum to minimum value when

    the participants attitude is incongruent with the Courts decision, the predicted

    probability of strongly approving of the Court as an institution decreases by .19

    and the predicted probability of approving of the Court decreases by .14.

    Participants become more likely to disapprove of the Court (.11) when their

    predisposition is incongruent with the outcome of the case and their perception of

    procedural justice decreases. Finally, the predicted probability of strongly

    approving of the Court decreases by .13 when opinion-policy congruence is

    moved from its maximum congruence to incongruence with the Courts decision,

    while perceptions of procedural justice are held at their mean value (3.36).

    Supreme Courts decision, as procedural perceptions move from their maximum

    to their minimum the predicted probability of strongly approving of the

    Supreme Court justices decreases by .25 and the predicted probability ofapproving of the justices decreases by .15. The most substantively interesting

    change comes when perceptions of procedural justice are moved from their

    maximum to minimum value and participants policy predisposition is incon-

    sistent with the Courts decision. In this simulation, approval of the Court

    justices decreases by .32 and disapproval of the justices increases by .26.

    Perceptions of procedural justice do influence support for the Supreme Court

    justices. Negative perceptions of procedural justice decrease the predicted prob-

    ability of approving of the Supreme Court justices even when participants were

    simulated to favor the policy direction of the Supreme Courts ruling. Theseresults suggest policy matters, but so does how the public perceives the Supreme

    Court goes about conducting its business.

    Conclusion

    This research sought to uncover the psychological mechanism that mediates

    media coverage of the Court and subsequent support for the Court. Previous

    research has shown that the depiction of Court motives (i.e., legalistic, political,

    practical) shaped public support for the Court in its decision in the 2000 presi-

    dential election (Nicholson & Howard, 2003) and that media coverage of the

    research agenda by showing that differences in support for the Court can be

    attributed to how media coverage alters perceptions of procedural justice.

    Respondents in the procedurally fair condition have more support for the Court

    than respondents in the procedurally unfair condition. Moreover, the differences

    in levels of support can be attributed to how the media conditions affected per-

    ceptions of procedural justice.

    In addition, the results show procedural perceptions influence both support for

    the justices and support for the Court as an institution. Although diffuse support for

    the Court is relatively high and stable because it is grounded in core democratic

    values, the Courts legitimacy appears to be reinforced by a bias in information

    that focuses on the legality and fairness in the Courts decison-making process.

    Media frames provide one conduit of that information, but surely others exist. For

    instance, Gibson, Caldeira, and Spence (2003) find that there are multiple path-

    ways in which perceptions of the Courts rule by law can influence support. The

    results also indicate specific supportor at least support for the justicesis more

    malleable than support for the institution. To the extent the latter measure captures

    diffuse or long-term support for the Court, it would suggest that frequent exposure

    to negative procedural information over an extended period of time would erode

    the Courts legitimacy. Since the research design provides participants with a

    single exposure, it can only provide limited or suggestive evidence on the question

    of diffuse support for the Court. Cross-sectional and experimental data of the type

    in this study are also inadequate in addressing how people update their long-term

    attitudes about the Court. I leave questions associated with the latter to future

    research.

    A shortcoming of the research design is the empirical findings are attributed

    to all three dimensions of procedural justice equally. Although this is consistent

    with Tylers (1988) conceptualization of procedural justice, the dimensions of

    procedural justice should be independent of each other. It is conceivable some

    people can view the justices as untrustworthy or biased, while at the same time

    viewing the Court as representative. One dimension might play a stronger role in

    both perceptions of procedural justice and support for the Court.

    Additional research should also examine how expectations of the Court

    and perceptions of the Courts ability to meet those expectations shape support

    for the Court. Functional theories of communication show that information that

    directly addresses the psychological motivation(s) of the targeted attitude are

    perceived as higher in quality and containing more relevant information (Lavine

    and Snyder 1996). Information about the procedural justice should be effective

    at shaping citizens judgments about the Court because people perceive proce-

    dural justice as an important function of the judicial branch. The Court is

    suppose to function as an objective body making decisions based on the law

    rather than political or personal considerations. To the extent that perception is

    the case Ewing v. California. Eyewitnesses report the justices listened carefully to

    arguments on both sides of the debate before retiring to their chambers to deliberate

    on the pros and cons of each argument. A spokesman for Mr. Ewing released a

    statement prior to the Courts announcement today saying Mr. Ewing felt confident

    the U.S. Supreme Court would deliver a fair and neutral decision. The case

    originated after Mr. Ewing was sentenced to life in prison under Californias three

    strikes and youre out law for stealing three golf clubs. Attorneys for Mr. Ewing

    argue the penalty is too severe for the crime, but Californias attorney general argued

    the law targets career criminals. The District Court and Court of Appeals agreed to

    uphold the law, but Mr. Ewing appealed to the Supreme Court. Ed Lazarus, a law

    legal precedent. Although I do not agree with the law, one justice commented, it

    is not the Courts duty to compose legislation, but interpret and uphold the existing

    law. Donald Fagan, a supporter of Mr. Ewing, said that although he did not agree

    with the Supreme Courts decision, he applauded the Courts willingness to hear

    the case and will continue to fight against the California law. Walter Becker, a

    Washington D.C.The Supreme Court recently ruled by a 5-4 split to uphold

    the U.S. governments claim that it does not have to compensate Boeing Airlines

    for past export subsides in the case Boeing v. the United States. Eyewitness reports

    of the debate describe the oral arguments among the lawyers and justices as fierce.

    At one point, one justice appeared ready to argue the case himself for an attorney

    who could not answer his questions. A spokesperson for Boeing released a state-

    and the citizens of this country are tired of seeing the U.S. Supreme Court

    becoming politically involved in this issue. The Los Angeles Times and the

    Associated Press have recently been reporting accounts of Supreme Court Justices

    accepting vacations from special interest groups associated with the case. One

    justice declined requests to voluntarily excuse himself from the case due to a

    conflict of interest. The case originated after Boeing sought to collect government

    nine U.S. Supreme Court Justices who are not elected by the public announced

    their decision on this politically charged topic. Ed Lazarus, a law clerk for Justice

    Kennedy, reported the debate in the justices closed chamber was intense.

    Kennedy served as the swing vote, ruling against Boeing Airlines after defecting

    from a previous alliance within the Court. Lazarus remarked, The switched vote

    became so sensitive Kennedy told me to hide his work from other law clerks to

    avoid pressure from other justices to change his decision. Donald Fagan, an
