AI Research GUIDE

Getting Reliable Results When AI Finds Your Sources

AI tools like ChatGPT, Perplexity, Claude, and Gemini can now search the web and pull together sources for you in seconds — whether through NotebookLM's Deep Research, ChatGPT's web browsing, or Claude's web search.

That's incredibly useful, but it also shifts a key responsibility: instead of choosing your own sources, you're evaluating ones the AI chose for you.

This guide covers three parts to help you get better results and trust what comes back:

Part 1: Prompting for Better Sources

When you ask an AI to research something, the quality of your prompt influences the quality of sources it finds. You can't force perfect results, but you can guide the AI toward more reliable material.

The Problem with Basic Prompts

"Research the benefits of intermittent fasting"

...will return sources, but you have no influence over:

  • Whether they come from credible publishers

  • Whether they represent balanced perspectives

  • Whether they're current

  • Whether they're primary or secondary sources

  • The AI will find something. Your job is to steer it towards something useful.

Five Principles for Better Research Prompts

1. Specify the source types you want

Tell the AI what kinds of sources to prioritise and what to avoid.

Instead of:

"Research electric vehicle adoption in Europe

Try:

"Research electric vehicle adoption in Europe. Prioritise peer-reviewed studies, official government statistics, and reports from established research organisations. Avoid opinion pieces and industry marketing materials."

2. Request recency where it matters

For fast-moving topics, specify a time frame.

Instead of:

"Research AI regulation in the UK"

Try:

"Research AI regulation in the UK, focusing on developments from 2024 onwards. Prioritise official government sources, legislation, and analysis from legal or policy experts."

3. Ask for multiple perspectives on contested topics

Prevent one-sided source selection by making balance explicit.

Instead of:

"Research the effectiveness of remote work"

Try:

"Research the effectiveness of remote work. Include sources presenting different perspectives — both research supporting remote work benefits and research highlighting challenges or limitations. Prioritise academic studies and surveys with clear methodology over opinion pieces."

4. Request primary sources explicitly

Push toward original material rather than summaries and commentary

Instead of:

"Research the recent Supreme Court ruling on [topic]"

Try:

"Research the recent Supreme Court ruling on [topic]. Prioritise the original court decision, official court documents, and legal analysis from qualified legal scholars. Include the primary source document if possible."

5. Exclude source types you don't want

Be explicit about what to filter out.

Example:

"Research health benefits of meditation. Prioritise peer-reviewed medical and psychological research. Exclude wellness blogs, product marketing sites, and sources without named authors or citations."

Prompt Templates by Use Case

Adapt these templates to your specific research needs.

Academic or Professional Research

Research [TOPIC].

Source requirements:

- Prioritise peer-reviewed academic sources, official reports, and recognised expert analysis

- Include sources published within the last [X] years unless historical context is needed

- Exclude opinion pieces, blogs without citations, and marketing content

- Where possible, find primary sources rather than secondary reporting

If the topic is contested, include credible sources representing different positions.

Current Events or Policy

Research [TOPIC], focusing on developments from [DATE] onwards.

Source requirements:

- Prioritise official government sources, established news organisations with editorial standards, and recognised policy experts

- Include primary documents (legislation, official statements, court filings) where available

- For news reporting, prefer outlets with clear editorial policies and named journalists

- Exclude anonymous sources, unverified social media, and overtly partisan commentary

Note any significant disagreements between sources.

Business or Market Research

Research [TOPIC].

Source requirements:

- Prioritise industry reports from recognised analysts, official company filings, government statistics, and trade publications with editorial oversight

- Be cautious with company-produced content — include it for stated positions but note it may be self-serving

- Include multiple perspectives if there are competing views on market trends

- Note publication dates — market conditions change quickly

Flag any sources that may have conflicts of interest.

Health or Medical Information

Research [TOPIC].

Source requirements:

- Strongly prioritise peer-reviewed medical journals, official health body guidance (NHS, WHO, CDC), and systematic reviews

- Include the level of evidence where possible (randomised controlled trial, observational study, expert opinion)

- Exclude wellness blogs, alternative health sites without medical credentials, and anecdotal sources

- If scientific disagreement exists, represent the consensus view and note where credible dissent exists

This is for informational purposes — note that it does not constitute medical advice.

Investigative or Fact-Checking Tasks

Research [TOPIC/CLAIM].

Source requirements:

- Prioritise primary sources: original documents, official records, direct statements from people involved

- For secondary sources, prefer established investigative journalism with clear sourcing

- Cross-reference key claims — find multiple independent sources where possible

- Note the provenance of each source: who published it, when, and what access they had

- Flag any sources that rely on anonymous claims or cannot be independently verified

I need to verify this information, so source quality is critical.

What Prompts Can and Cannot Do

They can:

  • Guide the AI toward better source types

  • Reduce (but not eliminate) low-quality sources

  • Encourage balance on contested topics

  • Make your requirements explicit

They cannot:

  • Guarantee the AI follows instructions perfectly

  • Prevent all hallucinated or misrepresented sources

  • Replace your own verification

  • Force the AI to find sources that don't exist

Better prompts improve your starting point. You still need to check what comes back.

Part 2: Verifying AI-Found Sources

AI research tools can hallucinate sources, misrepresent what sources say, or select sources that aren't appropriate for your needs. Before relying on AI-found sources, run through these checks.

The Seven-Point Verification Check

1. Does the source actually exist?

AI can hallucinate URLs or mangle web addresses

  • Click through to the actual page

  • If you get a 404 error, search the article title directly

  • If you still can't find it, don't use it

Red Flag: A URL that looks plausible but leads to nowhere

2. Does it say what the AI claims?

The source exists, but the AI may have misrepresented it.

  • Read the relevant section yourself and not just the AI's snippet

  • Look for context that changes the meaning

  • Check whether opinions are presented as facts (or vice versa)

Red Flag: The AI's summary sounds more definitive than the original text

2. Does it say what the AI claims?

The source exists, but the AI may have misrepresented it.

  • Read the relevant section yourself and not just the AI's snippet

  • Look for context that changes the meaning

  • Check whether opinions are presented as facts (or vice versa)

Red Flag: The AI's summary sounds more definitive than the original text

3. Who published this and why?

Not all sources deserve equal trust.

  • Identify the publisher (news outlet, academic journal, company, individual)

  • Check if the author is named and has relevant expertise

  • Look for an "About" page; who runs this site?

  • Consider whether the publisher has a financial or ideological stake

Generic trust hierarchy:

  • Higher trust: Peer-reviewed journals, official government sources, established news organisations with editorial standards, recognised professional bodies

  • Medium trust: Reputable trade publications, named expert commentary, well-sourced journalism

  • Lower trust: Anonymous articles, company blogs on topics where they're selling something, content farms, unverified user-generated content

Red Flag: No author, no about page, no way to identify who's behind the content

4. When was it published?

Information ages at different rates.

  • Check the publication date

  • Consider whether the situation has changed since then

  • For fast-moving areas (technology, health, policy), even 6-12 months can matter

Red Flag: No visible date, or the date suggests the information may be outdated

5. Is this a primary or secondary source?

Primary sources are closer to the truth.

  • Primary: Original research, official documents, court filings, direct interviews, first-hand accounts

  • Secondary: News-reporting, summaries, analysis, commentary on primary sources

Where possible:

  • Trace secondary sources back to the primary source they cite

  • Prefer primary sources for important claims

  • be cautious if a claim only appears in secondary sources

Red Flag: Multiple articles all citing the same single source (circular sourcing)

6. What's Missing?

AI research finds sources, but not all sources

  • Consider what perspectives might be underrepresented

  • On contested topics, did it find sources from different viewpoints?

  • Are there obvious types of sources missing (academic research, official data etc.)?

  • Think about what search terms might find sources the AI missed

Red Flag: All sources share the same perspectives on a genuinely contested issue

7. Do multiple independent sources agree?

Corroboration increases confidence.

  • Cross-reference key claims across different sources

  • Check that sources are genuinely independent (not all citing eachother)

  • If only one sources makes a claim, treat it with more scepticism

Red Flag: A striking claim that appears in only one source

Quick Authority Checks

You don't need specialist software to assess source credibility. These quick checks work for most situations:

Check

What It Tells You

Can you find an "About" page?

Legitimate organisations identify themselves

Is the author named with credentials?

Anonymous content is harder to verify and trust

Does the site have ads everywhere?

Ad-heavy sites often prioritise traffic over accuracy

Does the site have ads everywhere?

Commercial motive may bias the information

Can you find this organisation mentioned elsewhere?

Real institutions have external footprints

Does the URL match a known organisation?

Watch for typosquatting and impersonation sites

When to Do a Full Check vs. a Quick Check

Full check (all seven points):

  • High-stakes decisions (health, legal, financial, professional)

  • Content you'll publish or share publicly

  • Claims that seem surprising or too good to be true

  • Contested or politically-sensitive topics

Quick check (existence, authority, currency):

  • Background research and general understanding

  • Low-stakes personal decisions

  • Well-established factual matters

Quick check (existence, authority, currency):

  • Casual exploration

  • Topics where you already have expertise and can spot errors yourself

Part 3: Choosing the Right Approach

AI research tools sit on a spectrum between convenience and control.

Approach

Speed

Control

Best For

AI finds and synthesises sources
(Deep Research, Perplexity, ChatGPT browsing)

Fast

Low

Initial exploration, time-pressured research, broad overviews

AI works with sources you provide
(NotebookLM with uploaded docs, ChatGPT/Claude with files)

Medium

High

Initial exploration, time-pressured research, broad overviews

Traditional research
(you find and read sources yourself)

Slow

Full

Critical decisions, original research, maximum reliability

For important work, consider a hybrid approach:

  1. Use AI research for initial exploration and source discovery

  2. Verify and filter the sources it finds

  3. Upload the vetted sources to a tool that works only from what you provide

  4. Generate outputs from the verified material

This captures the speed benefit of AI research while maintaining quality control

Final Reminder

AI research tools make finding information faster. They don't make verification unnecessary — they make it more important. The citations exist so you can check them. Use them.
