What Are The Main Types of Evidence?
Evidence
Observations and measurements that support, contradict, or refine a hypothesis or theory.
- In three main types of evidence you'll be dealing with are:
- Textual evidence (quotations, key moments, patterns in language or structure)
- Contextual evidence (relevant information about author, audience, purpose, or historical/cultural setting)
- Research evidence (information from primary and secondary sources that supports an interpretation)
- A useful way to think about evidence selection is this chain:
- Question or task → Claim → Evidence → Explanation (analysis) → Conclusion
- If any link is weak (for example, evidence that does not truly match the claim), the whole argument becomes shaky.
What Are Primary and Secondary Sources?
Primary Source
A source with a direct, first-hand connection to what is being studied, such as eyewitness accounts, interviews, surveys, photographs, audio/video recordings, and experimental data.
Secondary Source
A source that describes, interprets, evaluates, or comments on primary sources (without being first-hand itself), such as reviews, criticism, and many explanatory articles.
- Evidence selection is closely tied to source choice.
- In research, you usually draw evidence from primary and secondary sources, and you should be able to identify which is which.
- Primary sources are often powerful because they are close to the event or text, but they can still be biased or incomplete.
- Secondary sources can offer expertise and interpretation, but may introduce their own assumptions or agendas.
- In English, the literary text itself is typically a primary source for literary analysis.
- A review or a critical essay about that text is a secondary source.
What's The Role of Credibility and Bias?
Credibility
The degree to which a source or text is believable and trustworthy, based on evidence, expertise, transparency, and fairness.
Bias
Bias refers to a systematic preference or inclination that shapes how theories are constructed and applied.
- In an age of mass information, selecting evidence is not only about finding something that supports your point; it is also about deciding whether it is credible.
- A practical credibility check (especially useful for digital and media texts) asks:
- Who created this information, and what are their qualifications or role?
- Why was it created (to inform, persuade, sell, entertain, attack, defend)?
- What evidence is shown, and what is missing?
- When was it created (is it current and relevant)?
- How does it compare with other independent sources (corroboration)?
How Is Relevance A Filter?
- After credibility, the next test is relevance: does the evidence directly support the specific claim you are making?
- A piece of evidence can be true but irrelevant. For example:
- A quotation can be beautifully written but not connected to your argument.quotation can be beautifully written but not connected to your argument.
- A contextual fact can be interesting but not explain the author's choices.contextual fact can be interesting but not explain the author's choices.
- A statistic can be accurate but not measure what your claim is about.statistic can be accurate but not measure what your claim is about.
- To figure out if evidence is relevant, ask: "If I removed my explanation, would a reader still see how this evidence supports the claim?"
- If the answer is "no," either the evidence does not fit, or your analysis needs to do more work.
What's The Difference Between Representative vs. Cherry-Picked Evidence?
- Even credible, relevant evidence can be weak if it is unrepresentative.
- This happens when you choose only the details that suit your viewpoint and ignore the rest.
- In English, cherry-picking often looks like:
- Selecting one extreme quote that is not typical of the textone extreme quote that is not typical of the text
- Ignoring later moments that complicate your claimthat complicate your claim
- Using a single source that agrees with you, without checking alternatives that agrees with you, without checking alternatives
- Instead, aim for evidence that is:
- Representative (fits broader patterns in the text or across sources)
- Sufficient (enough to justify the claim, not just one thin example)
- Balanced (acknowledges complexity, especially for debatable claims)
- Do not confuse "strong" with "shocking."
- Evidence is strong when it is reliable and clearly supports your reasoning, not when it is the most dramatic line you can find.
How Can You Integrate Evidence?
- Evidence does not "speak for itself." In analysis, your job is to show how the evidence proves the claim.
- A reliable integration pattern is:
- Point (claim) → Evidence (quote/detail) → Method (technique or feature) → Meaning (what it suggests) → Effect (on audience/purpose)
- Also remember:
- Use quotation for precise language analysis.
- Use paraphrase for plot moments or broader ideas.
- Use summary sparingly, only to set up analysis.
- Aim for a 1:2 ratio: for every 1 line of evidence, write about 2 lines of explanation.
- If you have more evidence than explanation, you are probably under-analysing.
- What is the fundamental difference between a primary source and a secondary source when analyzing a literary text?
- What are the four specific criteria used to perform a credibility check on a source?
- How does cherry-picked evidence differ from representative evidence, and why does it weaken an argument?
- In the "Integration Pattern" (Point → Evidence → Method → Meaning → Effect), why is the Method step crucial for analysis?
