Multiple Choice

Answer: c
3. The knowledge gap hypothesis predicts that new information entering the media environment will:
a) Reduce political knowledge inequality by making information available to all b) Increase knowledge inequality because better-positioned groups benefit disproportionately from new information c) Have no effect on knowledge inequality because uptake is equally distributed d) Primarily benefit low-knowledge groups because high-knowledge groups are already saturated
Answer: b
4. Bakshy, Messing, and Adamic's 2015 study of 10.1 million Facebook users found that:
a) Algorithmic filtering was the primary driver of selective exposure to political content b) Individual choice, rather than the algorithm, was the primary driver of exposure to like-minded content c) Facebook users were heavily filtered into ideological bubbles with no cross-cutting exposure d) Social media algorithms had no measurable effect on political information exposure
Answer: b
5. The research finding that municipal borrowing costs increase after local newspaper closures is evidence of:
a) Newspapers' direct economic impact on municipal bond markets b) Reduced government accountability when local journalism disappears c) The preference of municipal governments for low-transparency financial arrangements d) The correlation between newspaper closures and economic decline in rural areas
Answer: b
6. Which statement about social media political information environments is most supported by the chapter's discussion?
a) Social media creates effective filter bubbles that prevent most users from encountering cross-cutting political content b) Twitter/X is representative of the general public's political views because it has the largest political discussion community c) False news spreads faster and further through social networks than true news d) Algorithmic curation of social media feeds has no effect on political information exposure
Answer: c
7. The Fairness Doctrine's repeal in 1987 is significant for the development of partisan media because:
a) It required cable news channels to provide balanced political coverage b) It removed a regulatory requirement for balance on controversial public issues, enabling explicitly partisan media formats c) It established the legal framework for Fox News to operate as a partisan outlet d) It required television stations to give equal time to all political candidates
Answer: b
8. ODA's Sam Harding documents that the media monitoring dashboard "covers traditional and mainstream digital media" but not community and informal digital media. This acknowledgment illustrates which of the textbook's recurring themes?
a) Data in Democracy: Tool or Weapon? b) The Gap Between the Map and the Territory c) Measurement Shapes Reality d) Who Gets Counted, Who Gets Heard?
Answer: c (Note: "d" is also defensible as a secondary theme; the primary connection is that measurement choices shape what counts as "the" media ecosystem.)
9. Levi Boxell, Matthew Gentzkow, and Jesse Shapiro's research found that polarization increased most rapidly among:
a) Heavy social media users in the 18-35 age group b) Older Americans with the lowest rates of social media and digital news consumption c) College-educated urban Democrats who consume the most political content d) Rural Republicans with limited access to broadband internet
Answer: b
10. Which media measurement tool would be most useful for tracking how different demographic groups are consuming political news across online platforms?
a) Nielsen People Meters b) comScore audience measurement c) Google Trends d) Wesleyan Media Project
Answer: b
Short Answer
11. Explain why the "three-network era" of American broadcasting did not produce informational equity despite creating a shared information environment. (3-4 sentences)
Model Answer: The shared information environment of the broadcast era was shared primarily among white, middle-class, English-speaking Americans who were the intended audience for network news. People of color, women, working-class communities, and other marginalized groups were systematically underrepresented both as subjects and producers of network news content. The apparent universality of "American" news actually reflected a dominant-group perspective that rendered other communities' experiences and concerns invisible. Shared information is not the same as equitable information.
12. Distinguish between "cross-cutting exposure" and "hostile cross-cutting exposure" and explain why the distinction matters for the filter bubble debate. (3-4 sentences)
Model Answer: Cross-cutting exposure refers to encountering political information from across ideological lines; hostile cross-cutting exposure specifically refers to encountering outgroup content that is hostile to one's own group or views. The distinction matters because research on incidental cross-cutting exposure (e.g., seeing political content from friends with different views on social media) finds that encountering hostile outgroup content may increase polarization rather than reduce it. This means that "opening" filter bubbles does not automatically reduce polarization: if what flows in is adversarial framing of political conflict, increased cross-cutting exposure could intensify rather than moderate polarization.
13. What is "intermedia agenda-setting" and how does media fragmentation affect it? (3-4 sentences)
Model Answer: Intermedia agenda-setting refers to the process by which elite legacy media (major newspapers, wire services) influence what other media outlets cover—setting a media agenda that then propagates through the broader information ecosystem. In the fragmented media environment, this process continues but is more contested and slower: social media now creates alternative agenda-setting pathways through viral content and trending topics that can elevate issues to salience independently of legacy media. The result is a more complex, multi-directional agenda-setting process rather than the one-directional flow from elite press to other media that characterized the three-network era.
14. Sam's ODA dashboard tracks six different data streams rather than relying on a single measurement source. Why is multi-stream monitoring analytically superior to single-source measurement, and what does this illustrate about measurement in political analytics? (4-5 sentences)
Model Answer: Single-source measurement captures only the portion of the media ecosystem that source covers, producing systematic blind spots—a television-only monitor would miss all digital political discourse; a Twitter-only monitor would miss older voters' media environments. Multi-stream monitoring reduces these blind spots by triangulating across different data sources, each of which covers different portions of the ecosystem with different strengths and weaknesses. When multiple independent data sources point to the same pattern, confidence in that pattern is substantially higher than when it rests on a single source. This illustrates a broader principle in political analytics: measurement choices shape what analysts can see, and no single measurement tool captures the full reality of the phenomenon being studied. Explicitly documenting what each measurement approach misses is as important as documenting what it reveals.
