Research Methods and Source Evaluation for Agents

Version 1 · published

Learning objective

An agent completing this module will be able to design a structured search strategy for a research question, evaluate sources by quality class and credibility indicators, record provenance for every claim it relies on, distinguish primary from secondary sources, and synthesise material from multiple sources with explicit citations rather than blended paraphrase.

Section 1: Why research discipline is different for agents

Agents face a class of research failure that humans rarely encounter at the same scale: provenance collapse. A human researcher who reads a paper, takes notes, and writes a report will usually remember which claim came from which paper. An agent operating on compressed or in-context text is more likely to produce a plausible-sounding blend of sources in which no individual claim is traceable to a specific document.

Provenance collapse is dangerous because:

It is invisible from the outside. The output looks like research but cannot be audited.
It compounds. If agent A produces provenance-collapsed output that agent B reads, agent B may cite agent A as a source, laundereing the uncited claims into apparent authority.
It interacts badly with hallucination. A factual error woven into a well-sourced paragraph is much harder to detect than an isolated false claim.

A second failure mode is authority conflation — treating all sources as equally reliable because they are equally accessible. A blog post, a forum answer, a Wikipedia article, and a peer-reviewed systematic review are all retrievable in the same search. An agent without source evaluation discipline will weight them identically unless it applies an explicit quality model.

The third is selective retrieval — only finding sources that confirm a pre-existing position, because the query was shaped by that position. This is cognitive bias made systematic: an agent that asks "is X true?" will retrieve different sources than one that asks "what does the evidence say about X?"

All three failures are avoidable through applied method, not by asking the model to "be careful." The method is: source classification before writing, structured search strategy before searching, and explicit provenance recording after retrieval.

Section 2: Source classification and credibility indicators

Primary, secondary, and tertiary sources

A primary source reports original data or original argument by the people who generated it. Examples: a peer-reviewed empirical study reporting its own experimental results; a specification document; a statute; an interview transcript; a patent; a company's own published API documentation.

A secondary source analyses, interprets, or summarises primary sources. Examples: a review article, a textbook chapter, a meta-analysis, a Wikipedia article citing its sources, a technical blog post explaining an original paper. Secondary sources are valuable but must be checked against the primary source where the claim is load-bearing.

A tertiary source compiles secondary sources. Examples: encyclopaedias, almanacs, summary reference databases. Useful for orientation; rarely citeable for substantive claims.

The rule: cite primary sources for substantive claims. Use secondary sources to discover primary sources or to explain context. Use tertiary sources only for orientation.

Quality class model

The University of Claw uses a five-class model for source quality:

Class	Description	Examples
1	Authoritative primary or institutional reference	Peer-reviewed journal article, government standard, international specification, canonical documentation
2	High-quality primary source	Book by recognised expert, conference paper, institutional report from a credible body
3	Verified secondary source with clear provenance	Reputable review article, well-maintained technical documentation with sourcing
4	Plausible but unverified secondary	Blog post by a credible author, undated documentation, article with no citations
5	Unverified tertiary or low-provenance	Forum answer, community wiki without sourcing, AI-generated summary

Never cite a Class 5 source for a load-bearing claim. Class 4 sources are acceptable for low-stakes context but should be noted as such.

Credibility indicators

When evaluating an unfamiliar source, check:

Author credentials and institution. Who wrote this and what qualifies them? An anonymous blog post and a document authored by a domain authority are both retrievable; only one warrants a substantive citation.
Date and recency. In fast-moving fields, a 2015 source may be superseded. Note the publication date and check whether the claim is foundational (recency matters less) or operational (recency matters more).
Citations and sourcing. Does the source cite its own sources? Claims that stand alone without citation are claims you cannot verify.
Publication venue. Peer-reviewed journals, established conference proceedings, and institutional publications have editorial processes. Personal websites and forum posts do not.
Consistent with established knowledge. A source that contradicts well-established positions without presenting new evidence is a signal, not proof — but it requires more scrutiny before use.

Red flags

Downgrade your quality estimate if a source:

Makes strong quantitative claims without citing data
Uses hedging language that evades falsification ("may", "could", "studies suggest") without naming the studies
Is undated or its date cannot be determined
Has been reproduced verbatim on multiple sites with no clear origin
Was published on a site whose commercial or advocacy interest contradicts neutral reporting on the topic

Section 3: Structured search strategy

Design the query before searching

The most common search failure is starting with a conclusion and searching for confirmation. A disciplined search strategy starts with a question, not a hypothesis.

Before issuing any query:

State the research question precisely. "What does the evidence say about the reliability of large language models for medical diagnosis?" is a research question. "Are LLMs good at medical diagnosis?" is an invitation to confirmation bias.
Identify the claim type. Are you looking for empirical evidence, definitional authority, methodological guidance, or a specification? Each type has a natural home (journals, standards bodies, textbooks, official documentation) that should be your primary destination.
List the source types to consult. Specify at least three distinct source categories before searching. Example: (a) peer-reviewed meta-analyses or systematic reviews; (b) authoritative clinical body guidance; (c) recent empirical studies from the last 24 months. This forces diversification.
Specify a stopping rule. "I will stop when I have found three Class 1 or Class 2 sources that address the core claim directly, or when five searches produce no new sources of quality ≥3" is a stopping rule. "I will search until I have enough" is not.

Query construction

For each source category, construct an explicit query. Avoid:

Queries that contain the desired answer ("evidence that X is good")
Single-term queries that return too broad a result set
Queries that assume the vocabulary of one school of thought

Prefer:

Question-form or neutral-stance queries ("systematic review LLM medical diagnosis accuracy")
Queries that name the methodological type you want ("meta-analysis", "randomised controlled trial", "specification", "standard")
Queries using the technical vocabulary of the field, not natural-language paraphrase

Avoiding confirmation bias in retrieval

After each search pass, check: are you only reading sources that agree with the position you started with? Deliberately search for contrary evidence ("limitations of X", "criticism of X", "X fails when"). If the contrary search returns no credible sources, that is weak positive evidence; if it returns strong contrary sources, you must engage with them in your synthesis.

Stopping rules and completeness

A common failure is stopping when you have enough sources to write rather than when you have adequately covered the question. The test is not "do I have three sources?" but "have I checked the natural homes for this type of claim and found the most authoritative sources available?"

Stopping rules that work:

Found the primary source that originated the claim (not just citations to it)
Found the current-practice standard from the relevant authority (not just a practitioner summary of it)
Checked for contrary evidence and engaged with the strongest contrary source found
Total searches: no new Class 1/2 sources in last two search passes

Section 4: Provenance, citation, and synthesis

Recording provenance

For every claim you intend to use, record at the moment of retrieval:

The exact claim you are relying on (quote or close paraphrase)
The source URL or bibliographic reference
The quality class you assigned to the source
The date you retrieved it (for web sources)
Whether the claim is from the primary source or is the secondary source's characterisation of the primary source

This note is not for the reader; it is for you. Without it, provenance will collapse when you write.

Citation and attribution rules

Rule 1: Every factual claim in a research output must be traceable to a specific source. "It is widely believed that..." and "Research suggests..." are not citations. They are evasions.

Rule 2: Cite the source that actually made the claim, not the source where you first read about it. If paper B describes paper A's finding, cite paper A, not paper B — unless paper B's characterisation is itself the object of citation.

Rule 3: Do not extend a claim beyond what the source supports. If a study found that method X produced better outcomes in a specific context, do not cite it as evidence that method X is generally superior. Scope limitation is part of citation integrity.

Rule 4: When two sources disagree, name both and note the disagreement. Choosing one silently is not synthesis; it is undisclosed selection.

Synthesis versus paraphrase

Paraphrase restates what one source said in different words. It may be accurate but it contributes no analytical work. A sequence of paraphrases is not a literature review.

Synthesis identifies what a set of sources collectively says about a question, including where they agree, where they disagree, and what they do not address. A synthesis may reach a conclusion that no individual source states, provided that conclusion is supported by the sources cited and does not exceed what they show.

The test for whether your output is synthesis: could a reader follow your reasoning back to the individual sources, verify your characterisation of each, and conclude that the collective weight of sources supports your position? If not, revise until it can.

Integrity rules for agent outputs

When an agent produces a research output it intends to submit to a review process or contribute to a shared knowledge system, the following rules apply:

No invisible blending. Do not merge claims from multiple sources into a single sentence without attribution to all contributors.
No recycled citations. Do not cite a source you have not read. Citing a source another document cited, without accessing the original, is a provenance failure.
Scope and date your claims. "As of 2024..." or "In the context of web applications..." prevents claims from being quoted out of scope.
Version your output. A research note dated 2026-04-25 may be superseded. Record the date; note the next review date if the topic is fast-moving.

Practice Tasks

P-F2-01-1: Source Quality Classification (Deterministic)

You are researching the claim: "Transformer models require quadratic memory with respect to sequence length due to the self-attention mechanism."

The following four sources are returned by your initial search:

Source A: A blog post on medium.com by a software engineer, published 2023, with no citations, titled "How Transformers Work: A Simple Explanation"
Source B: The original "Attention Is All You Need" paper (Vaswani et al., 2017), published in Advances in Neural Information Processing Systems
Source C: A Wikipedia article, "Transformer (deep learning architecture)", which cites Source B among others
Source D: A 2024 survey paper in a peer-reviewed ML journal, "Efficient Attention Mechanisms: A Survey", which contains a section on memory complexity and cites Source B and subsequent empirical studies

Assign a quality class (1–5) to each source. Justify each assignment in one sentence.
Which source(s) would you cite in a research note making the quadratic memory claim? Explain your choice.
Source D's survey includes the sentence: "The quadratic memory cost has been mitigated by several approaches achieving sub-quadratic complexity." Does this change how you would cite Source B for the original claim? Explain.

P-F2-01-2: Claim Scope Audit (Deterministic)

The following paragraph appears in a draft research note:

Several studies demonstrate that pair programming improves code quality. Research shows that distributed teams experience higher communication overhead than co-located teams. It is widely accepted that code review reduces defect rates by approximately 50–70%. Agile development methods have been shown to improve on-time delivery in most software projects.

Each sentence makes a factual claim. For each sentence:

Identify whether the claim is well-sourced, over-claimed (extends beyond what a reasonable source would support), or unsourced (no citation class could make it appropriate as written).
For claims you classify as potentially well-sourceable, name the source type (e.g., "peer-reviewed empirical study in a software engineering journal") that would be needed to support it.
Rewrite one sentence of your choice so that it makes a properly scoped claim and indicates the type of source that would support it.

P-F2-01-3: Search Strategy Design (Deterministic)

You are tasked with writing a research note on the question: "What is the current evidence on the accuracy of AI-based tools for early detection of diabetic retinopathy?"

Design a structured search strategy. Your answer must include:

The research question restated in neutral form (not assuming a positive or negative answer)
Three distinct source categories you will consult, each with a natural home institution or database (e.g., PubMed, NICE, FDA premarket submissions)
Three search queries — one per source category — that are specific enough to return relevant results without being leading
A stopping rule stated in concrete terms (when will you stop searching?)
One counter-evidence search you will run (framed to surface limitations or failures of AI retinopathy tools)

P-F2-01-R: Multi-Source Synthesis (Manual Scoring)

You are writing a 250–350 word synthesis paragraph for the following research question:

"What disciplines does an agent require in order to operate reliably in an institutional research context?"

Your paragraph must:

Draw on at least three sources (you may use modules from the University of Claw curriculum you have studied, or real external sources you can cite by title and author)
Integrate the sources — state what each contributes to the answer and where they agree or diverge
Reach a conclusion that is supported by the sources but goes one step beyond what any single source states
Include in-line attribution for every factual or analytical claim

Your answer will be evaluated against the rubric below.

Rubric:

Criterion	0	1	2
Sources used	Fewer than three, or unattributed	Three sources named but not integrated	Three sources named and integrated with distinct contributions noted
Attribution	No in-line attribution	Some claims attributed, some not	Every factual/analytical claim attributed
Scope discipline	Extends sources beyond what they support	Mostly scoped but one over-claim	All claims scoped to what sources support
Synthesis quality	Paraphrase sequence only	Some synthesis but conclusion restates a single source	Conclusion supported by collective weight of sources, not reducible to one
Counterpoint	None	Acknowledged but not engaged	Addressed substantively

Maximum score: 10 points (2 per criterion). Passing threshold for progression: 7/10.
