Section B: True/False with Justification

Identify whether each statement is True or False and write one to two sentences justifying your answer.

16. Professional fact-checkers are qualified to evaluate whether a political policy is a good idea.

17. PolitiFact won a Pulitzer Prize for its fact-checking work.

18. The backfire effect was confirmed by multiple independent replication studies.

19. The IFCN Code of Principles has strong legal enforcement mechanisms that can prevent decertified organizations from operating.

20. Research shows that crowdsourced news source quality ratings are always less accurate than professional fact-checker ratings.

21. News deserts are primarily an urban phenomenon concentrated in major cities.

22. Wood and Porter (2019) found that corrections had no effect on highly partisan respondents.

23. The selection of which claims to fact-check is itself an editorial decision that can introduce bias into the fact-checking process.

24. The "healthy information diet" concept implies that consuming only high-quality sources from a single political perspective is sufficient.

25. FactCheck.org was the first major standalone public-facing fact-checking organization in the United States.


Section C: Short Answer

Answer each question in 75–150 words.

26. What is the "partisan credibility problem" in fact-checking, and why does it create a structural challenge that cannot be solved by simply improving the quality of fact-checks?

27. Explain what "claim selection bias" is and how it differs from "methodology bias" in fact-checking. Why is the distinction important for evaluating Tariq's challenge at the beginning of the chapter?

28. What did the chapter describe as fact-checking's "archival function," and why does the Nuremberg parallel help illustrate it?

29. Explain why the news desert problem is categorically different from the filter bubble problem as a threat to information quality.

30. What does the "community trust map" reveal that a general source evaluation protocol does not?


Section D: Applied Scenario

31. A friend sends you a video clip of a political speech with the message: "This is shocking — they just admitted everything. You need to see this." The clip is 45 seconds long and has been shared 85,000 times. Using the source evaluation protocol from Section 32.13, describe the specific steps you would take to evaluate this clip before deciding whether to share it. What are the most likely ways this clip could be misleading even if every word in it is accurate?


Answer Key (Selected Items)

1-b | 2-c | 3-b | 4-b | 5-c | 6-a | 7-b | 8-b | 9-b | 10-b | 11-b | 12-b | 13-b | 14-b | 15-b

  1. False. Professional fact-checking explicitly confines itself to verifiable factual claims, not value judgments or policy preferences. Evaluating whether a policy is a good idea is opinion, not fact-checking.

  2. True. PolitiFact won the Pulitzer Prize for National Reporting in 2009.

  3. False. Subsequent research largely failed to replicate the backfire effect. Nyhan and Reifler themselves later found it was less robust than their original study suggested.

  4. False. The IFCN Code is a certification standard, not a legal regulation. The only sanction is loss of certification; there are no legal mechanisms to prevent decertified organizations from operating.

  5. False. Nyhan et al. (2020) found that diverse crowdsourced ratings correlated well with professional fact-checker ratings for widely known sources, though they were less reliable for obscure or borderline sources.

  6. False. News deserts are disproportionately concentrated in small towns and rural areas. Abernathy's research found that more than 200 counties had no local newspaper, and losses were not primarily urban.

  7. False. Wood and Porter (2019) found corrections consistently reduced belief in false claims, including among highly partisan respondents, though the effect was partial rather than complete.

  8. True. The selection of which claims to investigate involves editorial judgment about importance, checkability, and audience, and is one of the primary ways structural bias can enter the fact-checking process.

  9. False. A healthy information diet requires diversity of sources and perspectives. A monoculture of even high-quality sources from one political perspective produces a limited and potentially distorted epistemic environment.

  10. True. FactCheck.org, launched in 2003 by the Annenberg Public Policy Center, was the pioneer of the standalone public-facing fact-checking model in the United States.
