Comprehensive Study Notes on Political Science: Citizen Competence, Public Opinion, and Electoral Behavior
Citizen Competence
In the influential work An Economic Theory of Democracy (), Downs presents a theoretical framework using a spatial model to explain how political parties converge toward the ideological center. This strategic convergence ensures parties remain distant enough from one another to retain extremist supporters while capturing median voters. Downs argues that parties develop policies specifically to win elections, rather than the alternative view that elections are tools to implement pre-existing policy agendas. Central to this theory is the concept of bounded rationality, describing a state where voters are rational actors who nonetheless possess insufficient knowledge to make perfect decisions. To navigate this, voters compute "party differentials" by comparing actual utility and perceived probable utility. According to Downs, voters only resort to evaluating performance when the calculated party differential equals . Downs' calculus of voting, based on the perceived benefits of an election, leads to the mathematical finding that it is technically irrational for almost any individual to vote. Later, Riker and Ordeshook () revised this model by adding the variable of civic duty to the equation, formally represented as . Downs also posits that shifts in the cost () of voting can alter the distribution of political power, noting that the combined costs of information acquisition and the physical act of voting often disenfranchise those in low-income brackets.
Converse (), in The Nature of Belief Systems in Mass Publics, posits that the vast majority of the public lacks a sophisticated understanding of politics. He identifies a hierarchy of conceptualization levels among voters: ideologues, near-ideologues, group interest, nature of the times, and those with no issue content. His research found that only individuals categorized as ideologues or near-ideologues exhibit any measurable level of ideological constraint. Converse cites historical movements such as the Nazi Party and the Abolitionist Republicans to illustrate these phenomena, suggesting that mass support often lacks underlying ideological depth.
In contrast, Ansolabehere et al. () argue in The Strength of Issues: Using Multiple Measures to Gauge Preference Stability, Ideological Constraint, & Issue Voting that citizens are more politically sophisticated than typically credited. Their theory suggests that issue preferences possess significant explanatory power in presidential vote choice, reaching levels nearly equivalent to party identification. They found that most variations in preferences—such as the instability identified by Converse—are actually the product of measurement error. By averaging survey items regarding the same issue areas, a clearer and more stable picture of voter preference emerges.
Achen and Bartels (), in Democracy for Realists: Why Elections Do Not Produce Responsive Government, challenge the existence of a truly responsive democracy. They argue that citizens do not make political choices based on policy preferences but are instead poorly informed agents who vote according to social identities. Partisanship, in their view, is not a vessel for ideology but a reflection of social belonging and group judgments. Any policy content found in election outcomes stems from the existing relationship between political parties and established social groups. Their work includes a critique of the retrospective voting model, which suggests voters exert control by assessing incumbent performance. They argue that while effective accountability depends on the ability to attribute well-being to government actions, "blind retrospection"—retrospective voting without sufficient knowledge—fails to provide meaningful accountability. Critics of Achen and Bartels argue that their framework unfairly blames individual voters while failing to account for structural inequality.
Public Opinion
Zaller (), in The Nature & Origins of Mass Attitudes, provides a nuanced account of public opinion, suggesting that even when people appear inconsistent or contradictory over time, they are expressing genuine feelings rather than a lack of authenticity. Zaller bridges the perspectives of Achen and Converse, arguing that true opinions exists but are complex. He introduces the Receive-Accept-Sample (RAS) Model, defined by four axioms. The Reception Axiom states that greater cognitive engagement with an issue increases the likelihood of understanding political messages about that issue. The Resistance Axiom posits that people resist arguments that conflict with their predispositions, but only if they recognize the relationship between the message and those predispositions. The Accessibility Axiom describes a "top of the head" effect where recently recalled thoughts are more easily accessed. Finally, the Response Axiom states that individuals formulate responses based on considerations that are most immediately salient to them.
Delli Carpini et al. (), in What Americans Know About Politics & Why It Matters, observe that when measured against the standards of what a citizen "ought" to know, the American public appears largely ignorant of government and political details. They clarify, however, that the public is not apathetic; rather, people attempt to interpret the world through plausible answers that reflect biases found in their information environment. Their findings emphasize that a broadly and equitably informed citizenry is vital for democratic success. Critics argue that Delli Carpini et al. set excessively high knowledge standards and overlook the impact of political inequality.
Chong et al. (), in When Self-Interest Matters, explore the conditions under which citizens act on their own interests. They argue that people are more likely to recognize and act according to self-interest when the stakes are clearly defined or specifically primed. While priming sociotropic (nation-wide) considerations can weaken this relationship, it does not eliminate it. Furthermore, individuals with a smaller stake in an issue are more likely to be swayed by symbolism and values. The authors conclude that while self-interest is significant when evident, internal predispositions can override it in other contexts.
Jennings et al. (), in Politics Across Generations: Family Transmission Reexamined, investigate partisan socialization within families. They theorize that children are most likely to adopt the political orientations of their parents if the household is highly politicized and if the parents offer consistent cues. Their findings show that parental influence on partisanship occurs at a rate similar to influence over religious beliefs and church attendance. They conclude that children from politicized households are generally more attuned to the broader political landscape.
Groenendyk and Krupnikov (), in What Motivates Reasoning? A Theory of Goal-Dependent Political Evaluation, propose that information processing is driven by whichever goals are made salient by a particular context. Their findings suggest that when politics is framed as a debate, individuals are motivated to argue in favor of their own side. Conversely, if politics is framed as deliberation, individuals are motivated to engage in open-minded processing and seek consensus.
Heuristics & Cue-Taking
Brady and Sniderman (), in Attitude Attribution: A Group Basis for Political Reasoning, argue that citizens use a "likability heuristic" to estimate where strategically important political groups stand on major issues. This heuristic is based on personal feelings toward opposing groups and an "us vs. them" dynamic. Citizens simplify political calculations by assessing their own beliefs and their feelings toward a pair of opposing groups.
Dawson (), in Behind the Mule, explores the "Black utility heuristic," which reinforces the concept of "linked fate" among African Americans. His theory posits that class differences have not replaced race as the primary driver of political interest. He finds that African American political choices are heavily shaped by perceptions of racial group interests, and that limited political choices often mask significant internal group differences.
Lupia (), in Shortcuts versus Encyclopedias, examined California insurance reform elections to determine if voters need deep knowledge to make informed choices. His findings show that voters who lack "encyclopedic" information use heuristics—specifically shortcuts about which organizations support or oppose a measure—to vote effectively as if they were fully informed. These signals allow voters to make accurate inferences regardless of their technical knowledge.
Fortunato and Stevenson (), in Heuristics in Context, theorize that there is contextual variation in how people use heuristics. Their research found that constituents represented by loyal partisan senators are more likely to utilize the partisan heuristic compared to constituents represented by senators with less consistent loyalty to their party.
Broockman et al. (), in Heuristic Projection: Why Interest Group Cues May Fail to Help Citizens Hold Politicians Accountable, identify a phenomenon termed "heuristic projection." Their findings suggest that when an interest group misalignment exists—specifically when a group with views different from the voter gives a politician a positive rating—voters mistakenly infer that both the group and the representative share their own views. This leads to an erroneous increase in approval for the representative, demonstrating that cues can sometimes hinder accountability.
Participation & Turnout
In Downing's () spatial model, voter turnout is linked to the calculus of voting. He posits that since parties formulate policies to win elections and voters operate under bounded rationality, voters calculate a party differential to decide if voting is worthwhile. Because the perceived benefits of an election are often low compared to the costs () of information and the act of voting, the model suggests a disenfranchisement of low-income groups for whom these costs are relatively higher.
Brady et al. (), in Beyond SES: A Resource Model of Political Participation, move past simple socioeconomic status to outline a specific resource model. They identify time, money, and civic skills as the critical resources required for political involvement. Their findings demonstrate that these three factors have a powerful and direct effect on an individual’s overall level of political activity.
Lewis-Beck et al. (), in The American Voter Revisited, argue that citizens can understand broad party differences without possessing granular knowledge. For a citizen, the act of voting involves a calculation that the election is important enough to warrant the effort. They identify parents as primary agents of socialization who pass down partisanship. Findings suggest that higher psychological involvement leads to a higher propensity to vote, with other significant factors including close elections, age, education, mobilization, and registration status. While they find citizens have sophisticated political reasoning, they note a lack of views based on abstract principles.
Valentino et al. (), in Election Night’s Alright for Fighting: The Role of Emotions in Political Participation, examine emotional catalysts for voting. They found that anger is a significantly more powerful motivator for political participation than either anxiety or enthusiasm, demonstrating a distinctive influence on mobilization.
Coppock and Green (), in Is Voting Habit Forming? New Evidence from Experiments & Regression Discontinuities, theorize that individuals can become habituated to voting in certain types of elections. Their findings confirm that habituation occurs, though the degree to which the habit persists varies based on individual attributes and the specific electoral context.
Social But Mostly Partisan Identification
MacKuen et al. (), in Macropartisanship, propose that national-level partisanship varies systematically and follows a punctuated equilibrium model. They found that macropartisanship is influenced by economic evaluations (consumer sentiment) and presidential approval. While the underlying party system remains stable, medium-term shifts are large enough to have significant electoral consequences.
Huddy et al. (), in Expressive Partisanship: Campaign Involvement, Political Emotion, & Partisan Identity, distinguish between two forms of engagement. "Instrumental partisanship" suggests candidates succeed by syncing with public preferences, while "expressive partisanship" prioritizes symbolic identity and emotional connection. Their research found strong evidence that political engagement is primarily driven by expressive partisanship, emphasizing the importance of symbolic belonging.
Junn (), in The Trump Majority: White Womanhood & the Making of Female Voters in the US, utilizes intersectionality to analyze the positionality of white women, whom she describes as occupying a "velvet glove" position: in sex but in race. She theorizes that political rhetoric invoking "White womanhood" explain why a majority—specifically —of White women voted for Trump in , urging political scientists to adopt intersectional analytical lenses.
Partisan Polarization
Abramowitz and Saunders () argue in Is Polarization a Myth? that ideological polarization has dramatically increased among both the public and political elites since the . Countering researchers who suggest polarization is overstated, they find that it effectively energizes the electorate and stimulates overall participation.
Druckman et al. () explore How Elite Polarization Affects Public Opinion Formation, finding that polarization among elites directly impacts the public. Their findings show that elite polarization intensifies the power of party endorsements on personal opinions and reduces the impact of substantive information. Furthermore, citizens develop greater confidence in these new opinions, even if they are less grounded in facts.
Mason (), in “I Disrespectfully Agree”: The Differential Effects of Partisan Sorting on Social & Issue Polarization, makes a distinction between social and issue position polarization. Social polarization is characterized by partisan bias, activism, and anger. Mason found that while social polarization is rising due to "sorting" (the alignment of partisan and ideological identities), issue position polarization is not. Consequently, the United States is a nation that largely agrees on actual policies but remains bitterly divided socially.
Iyengar et al. (), in The Origins & Consequences of Affective Polarization in the United States, define affective polarization as the animosity between political parties originating from partisanship's role as a social identity. Their research finds that this affect influences behaviors outside of politics; for instance, individuals are increasingly unwilling to socialize across party lines.
Egan (), in Identity as Dependent Variable, identifies a process of self-categorization and depersonalization. He theorizes that because partisanship and ideology have become dominant social identities, a small but significant portion of Americans will actually shift their secondary identities to bring them in alignment with their political views.
Vote Choice
Downs () provides the baseline for vote choice through the spatial voting model, where voters choose the party closest to them in ideological space to maximize utility. As previously noted, this involves calculating party differentials and evaluating incumbent performance as a tie-breaker. This economic approach emphasizes that voters are rational actors minimizing costs and maximizing benefits.
Fiorina (), in Economic Retrospective Voting in American National Elections, proposes an Economic Retrospective Voting Model where personal economic conditions impact presidential vote choice. He found no systematic relationship between personal economics and the decision to vote or abstain. However, personal economic health does affect who someone votes for. Interestingly, this relationship was positive before and became negative thereafter.
Achen and Bartels () reiterate that vote choice is largely driven by social identities rather than policy. They focus on the retrospective voting model, pointing out that voters assess the performance of incumbents to exert control. However, they maintain that unless voters can accurately attribute well-being to government action, this form of accountability is flawed.
White and Laird (), in Steadfast Democrats, theorize the existence of "racialized social constraint." This is defined as the enforcement of group-aligned behavior through social sanctioning, driven by high levels of group consciousness and residential segregation. In an experiment manipulating the race of an interviewer, they found that the presence of a Black confederate significantly increased the social pressure for Black respondents to donate to Barack Obama's campaign.
Mass Media Effects
Prior () examines how increased media choice—driven by cable television and the internet—affects political knowledge. He theorizes that greater choice allows people to easily find their preferred content. His findings show that this widens the gap in political knowledge and turnout: those who prefer news becomes more informed, while those who prefer entertainment "tune out" and succumb to the distraction.
Gerber et al. () conducted the first large-scale randomized field experiment on televised campaign advertising. They found that while televised ads have a strong persuasive effect on voting preferences, this effect is psychological in nature and is highly short-lived, much like the effects of priming.
Cacciatore et al. (), in The End of Framing as We Know it, argue for a categorization of framing types in communication scholarship. They distinguish between "equivalence framing" (where logically identical information is phrased differently) and "emphasis framing" (where specific parts of information are intentionally highlighted).
Lajevardi (), in The Media Matters: Muslim American Portrayals, finds that media coverage of Muslims is overwhelmingly negative and has increased over time. Her research demonstrates that these negative portrayals increase hostility toward Muslim Americans and bolster public support for policies that target them.
Kim et al. () investigate toxicity in social media comments. Their theory of The Distorting Prism of Social Media suggests that frequent Facebook commenters are typically more interested in politics, more polarized, and more likely to use toxic language. They found that exposure to toxic comments increases the toxicity of subsequent comments, creating a self-reinforcing cycle.
Campaigns
Ansolabehere et al. () argue that negative "attack" advertising demobilizes the electorate. Their theory suggests that voters exposed to negative ads develop cynical attitudes regarding politician responsiveness. Their research found that negative ads can cause as many as of potential voters to abandon their intention to vote.
Valentino et al. () explore how subtle racial cues in ads prime racial attitudes, altering voting criteria. They found that while a wide range of implicit cues can prime these attitudes, "counter-stereotypic" cues (which challenge racial stereotypes) can dampen the effect. Importantly, the effect is triggered by the visual/narrative pairing rather than the simple presence of a Black image.
Brader (), in Striking a Responsive Chord, finds that political ads use images and music to evoke emotions, which then change how citizens participate. Cueing enthusiasm was found to motivate participation and activate existing loyalties. In contrast, cueing fear stimulates vigilance, increases the individual's reliance on contemporary evaluations, and facilitates easier persuasion.
Erikson and Wlezien () analyzed aggregate poll results from presidential elections between and . They found that campaigns do indeed impact outcomes. The observable variations in polling reflect real movements in electoral performance rather than mere survey error, suggesting voter preferences evolve in patterns throughout the campaign.
Kam and Zechmeister () highlight the power of name recognition. They theorize that name recognition influences candidate support by making the candidate seem more viable. A field study using yard signs in a county election demonstrated the robustness of this effect.
Misinformation & Conspiratorial Thinking
Oliver and Wood () found that half of the American public consistently endorses at least one conspiracy theory. Their findings indicate that conspiracism is not a product of authoritarianism or ignorance, but is predicted by a willingness to believe in unseen intentional forces and an attraction to Manichean (good vs. evil) narratives.
Flynn et al. () argue that political misperceptions are rooted in directionally motivated reasoning. This cognitive process limits the effectiveness of corrections, as facts are vulnerable to pre-existing biases. This leads to a state of polarization over the nature of reality itself.
Berinsky () investigated whether survey responses regarding political rumors (e.g., that Obama is a Muslim) reflect genuine belief or "expressive responding" (partisan cheerleading). His research found very little incidence of expressive responding, suggesting that surveys are generally accurate windows into the true, albeit potentially misinformed, beliefs of the public.
Schaffner and Luks () used the controversy over the crowd sizes at the inaugurations of Obama and Trump to test the same theory. In contrast to Berinsky, they found clear evidence of expressive responding, suggesting that some misinformation reported in surveys is the result of partisan cheerleading.
Anspach and Carlson () found that social media comments can distort the information found in news articles. Individuals presented with social media commentary were more likely to be misinformed, often reporting factually incorrect information found in the comments rather than correct information presented in the news preview itself.
Emotions
Banks and Valentino () argue that the primary emotional trigger of White racial attitudes has shifted. While disgust once accompanied beliefs about biological inferiority, anger has now fused with contemporary conservative ideas about race. Anger is uniquely powerful at boosting opposition to racially redistributive policies among radical conservatives.
Gadarian and Albertson () theorize that citizens who are anxious about immigration will seek out more information. However, they found that these subjects exhibit biased processing: they are specifically attracted to and more likely to remember and believe threatening information.
Banks et al. () explore how anger influences Black political action. While Black voters are generally homogenous in their support for equality, they differ on political strategies. Findings show that experiencing anger about race increases participation in indigenous Black organizations and protests, rather than supporting universalistic organizations or traditional voting.
Chudy () defines "racial sympathy" as White distress over Black misfortune. This sentiment shapes public opinion for a nontrivial set of White Americans, motivating support for policies that benefit African Americans. This sympathy is particularly activated when policies draw attention to Black beneficiaries and often persists even when negative stereotypes are present.
Mobilization
Rosenstone and Hansen () outline a hierarchy of mobilization targets, beginning with people known by the candidate, followed by people in central social network positions, those whose actions are most effective, and those likely to respond. They identify two paradoxes: the voting paradox (one vote doesn't change the outcome) and rational ignorance. They find that mobilization works by subsidizing the costs of participation and that personal-level variables do not explain changes in turnout over time; instead, one must look at strategic mobilization and social networks.
Valenzuela and Michelson () analyzed ethnic and national identity appeals to Latinos in California and Texas. They found that the effectiveness of these appeals is conditional on the strength of identity within different communities and specific Latino subgroups.
Kalla and Broockman () conducted field experiments to test campaign persuasion. They found that campaign contacts and advertising generally have a "minimal effect" on vote choice. Persuasion only emerges if candidates take extremely unpopular positions, if campaigns invest heavily in identifying the few persuadable voters, or if contact occurs long before Election Day—though these early effects tend to decay.
Hall and Thompson () found that extremist candidates perform poorly because they inadvertently mobilize the base of the opposing party. They quantified extremism using the nominate scores of candidates' donors.
Walker () identifies a negative feedback loop regarding the criminal justice system. Proximal contact with the system results in mobilization because affected individuals are less likely to experience self-blame and are instead mobilized by a sense of injustice.
Beyond Voting
Hopkins () proposes the "politicized places hypothesis," suggesting that hostile reactions to immigrants occur when a community undergoes a sudden influx of immigrants at the same time as salient national rhetoric reinforces the immigrants as a threat.
Brown () utilizes intersectional analysis to show that women of color experience different styles of mobilization and interest. While Latinas and Black women may lag behind White and Asian women in traditional participation, they have outpaced their male counterparts. Privileged women are more likely to participate in nontraditional political forms.
Anoll () finds that race and neighborhood context moderate the social value of political activity. While Whites see less community incentive for participation, neighborhood characteristics generally outpace individual-level indicators in predicting how much a community rewards political activity.
Wasow () introduces "agenda seeding," describing how activists use disruptions to capture media attention. Nonviolent activism in the , particularly when repressed, moved media framing and public opinion toward civil rights. In contrast, protester-initiated violence shifted the media frame toward the need for social control.
Hopkins et al. () found surprisingly strong stability in partisan identity among Asian Americans and Latinos during the early Trump era, contradicting theories that these groups lack strong partisanship. They found little evidence of situational shifts in identity despite social threats.
Supplemental Theoretical Perspectives
Lazarsfeld et al. () argue in The People's Choice that mass media reaches a small subset of influential people who then pass information to less avid consumers. Lodge and Hamill () found that "political sophisticates" use partisan schemas to incorporate new information; they are less likely to recall information that is schematically inconsistent. Luskin () defined political sophistication as an additive measure of belief systems, composed of knowledge size, range, and interconnectedness.
Page and Shapiro () argue that the American public as a collective makes rational policy choices and possesses stable preferences. Lenz (), however, suggests that what looks like priming is actually learning: people learn their party's stance on an issue and then adopt it as their own. Levendusky () found that increased ideological sorting among the public is the result of polarized terms used by political leaders to define their parties.
In the realm of vote choice, Campbell et al. () in The American Voter argue that party identification is largely inherited and is the primary driver of the vote, with independent voters being the least involved. Key () countered this, famously stating "voters are not fools." Fiorina () frames partisanship as instrumental and endogenous, meaning citizens evaluate a party's past performance to predict its future actions. Sinclair () emphasizes peer networks, finding that social pressure and influence significantly impact turnout and choice. Finally, Plutzer () describes the path to becoming a habitual voter through a developmental framework, and Gerber et al. () found that social pressure and potential sanctioning are powerful tools to increase voter turnout in large-scale field experiments.
