A cardiologist and a macroeconomist both publish articles on the effects of proposed healthcare legislation on hospital funding. Whose credibility should be weighted more heavily on the economic projections in the article?
AThe cardiologist, because their clinical experience gives them direct insight into hospital costs
BThe macroeconomist, because their domain expertise aligns with the economic modeling the projection requires
CNeither — only peer-reviewed journal articles count as credible sources for policy questions
DWhichever author has more total publications, regardless of subject area
Credibility is domain-specific: a cardiologist is an expert on coronary disease, not on macroeconomic modeling of healthcare funding. The macroeconomist's training, methodology, and professional experience align directly with the type of claim being made. This is the key insight — 'credibility' is never a single global attribute of a person, but a claim about their expertise relative to a specific question. The cardiologist may have useful qualitative insights, but their medical expertise does not transfer to econometric projection.
Question 2 Multiple Choice
You find two sources with opposing conclusions about the effects of a minimum wage increase. One is from a conservative economic think tank; one is from a progressive policy institute. Both use real data and cite peer-reviewed research. How should you treat this disagreement?
ADismiss both sources because think tanks and policy institutes are inherently biased
BAccept the progressive source because minimum wage increases are associated with worker welfare
CInvestigate what the sources actually disagree about — methodology, values, or scope — rather than simply picking the one that aligns with your view
DDefer to the source from a more prestigious institution, as institutional prestige determines credibility
Credible sources can and do disagree, and the right response is to analyze the nature of the disagreement — not to pick a winner or dismiss both. Think tanks have perspectives, not necessarily bias. A perspective means the analysis operates from a viewpoint; bias means systematic distortion of evidence. Both sources may be credible while disagreeing about underlying values (should we prioritize employment or wages?), methodology (what statistical controls are appropriate?), or scope (does this finding generalize nationally?). Naming the real disagreement is more intellectually honest than declaring one side correct.
Question 3 True / False
A peer-reviewed journal article can be trusted as correct because peer review guarantees the research is rigorous and error-free.
TTrue
FFalse
Answer: False
Peer review is a higher bar than editorial judgment or no review at all, but it does not guarantee correctness. Reviewers can miss methodological flaws, studies can be underpowered or poorly designed, and publication bias can skew what gets published. High-profile replication failures in psychology, medicine, and economics have demonstrated this. The right interpretation: peer review is a quality signal worth noting, not a guarantee of truth. A peer-reviewed source deserves more initial credibility than a blog post, but still requires scrutiny of methodology, sample size, conflicts of interest, and whether the findings have been replicated.
Question 4 True / False
A source written by an author with a clear political perspective can still provide credible, well-evidenced information.
TTrue
FFalse
Answer: True
Perspective and bias are distinct. Every source has a perspective — a viewpoint from which it sees the world. A perspective only becomes bias when it causes systematic distortion: cherry-picking data, misrepresenting opposing arguments, or suppressing contrary evidence. A conservative policy analyst and a progressive researcher can both produce credible, well-supported arguments within their frameworks. You assess bias by examining the reasoning, evidence selection, and treatment of counterarguments — not merely by identifying that a viewpoint exists.
Question 5 Short Answer
Explain the difference between 'perspective' and 'bias' in source assessment, and why the distinction matters.
Think about your answer, then reveal below.
Model answer: A perspective is a viewpoint or framework from which a source approaches a topic — every source has one, including ostensibly 'neutral' ones. Bias, in the relevant sense, means systematic distortion: selectively presenting evidence, misrepresenting opposing views, or suppressing contrary findings in ways that mislead the reader. The distinction matters because dismissing all sources with identifiable perspectives as 'biased' would eliminate most credible scholarship. You should instead assess whether the source's perspective leads to distortion by examining its evidence, methodology, and treatment of counterarguments — not by simply detecting that it has a viewpoint.
This distinction is particularly important in research writing. A student who conflates perspective with bias will either dismiss too many legitimate sources or naively accept sources as neutral when they are not. The practical skill is examining the source's reasoning process: Does it engage with contrary evidence? Does it represent opposing views fairly? Does it acknowledge limitations? These questions reveal bias; a political or disciplinary perspective alone does not.
