How to go down a rabbit hole

The method

The layers, in order

1. 0

   Write the question down first

   Before you open a tab. One sentence, in question form, on paper or in a note. Eight seconds. Later it is the only way to tell whether four hours answered anything or whether you just drifted.

   The difference “Why are all bananas the same variety?” is a question. “Bananas” is a browsing session.
2. 1

   Read the summary for what it is made of

   Almost nothing starts with an article. It starts with a forty-second clip, or a Reel your friend sent you, or a video essay you put on while doing something else. All of it is somebody’s summary, and the same question works on every kind: what is this built out of?

   On a short clip — TikTok, a Reel, a Short: there is no citation list and there was never going to be one. What you can get is the claim itself and any proper noun in it: a name, a place, a year, a piece of jargon. Screenshot it or write it down, because the specific numbers are usually in on-screen text rather than the audio, and captions get rewritten every time the video is reposted. Check the comments once for somebody naming a source, then leave the app. You are not going to find the bottom of anything inside it.

   Reposts are the trap. The clip you saw is often the fourth account to run the same footage, so the claim is travelling with no author attached and no way to ask anybody what they meant. If you search the exact phrasing and find eleven accounts saying it in the same words, you have found eleven copies, not eleven sources. Same failure as layer 7, arriving much faster.

   On a longer video, the description and the pinned comment are the citation list. Forty links or none tells you in five seconds what kind of thing you are holding. Open the transcript panel and you can search two hours of talking the way you search a page.

   On a wiki page, the article body is the least useful part. Go to References for what it is built from, Talk for what editors are still fighting over, and View history for what changed and who objected. The language sidebar is the underrated one: the German or Japanese article on your topic often cites entirely different material.

   From a chatbot, you have exactly one useful thing and it is in the next layer. It is not a source. It will hand you citations that look correct and do not exist, so treat every reference it gives you as a claim to check rather than a finding. Claude is free with a Pitt login. Always double-check what it tells you.

   Tell A claim with no footnote — in an article, or under a video, or in a chat window — is usually where the dive starts paying off.
3. 2

   Get the specialist’s word for it

   Specialists do not call it what you call it, and until you have their word you are searching a language nobody publishes in. “Why do old buildings have that green metal” gets you nothing. Patina and copper carbonate get you a century of literature.

   The term is usually sitting in the first paragraph of the Wikipedia article, or in its category tags at the bottom, or on a museum caption. This is also the one job a chatbot is good at: ask it what a field calls the thing you are describing, keep the words, discard everything else it said. And if the topic is not American, the word may not be in English.

   The moment you have it, run every search again from the top. You are looking for different documents now.

   Then move the query Same words, three indexes: Google Scholar, then the library catalog, then caption search. Three different worlds.
4. 3

   Chase the citation until nobody is summarizing

   A retelling loses something at every hop — a sample size, a date, a “may.” So follow the chain down: blog cites news story, news story cites press release, press release describes a study. Keep going until you reach something nobody is retelling. The study. The court filing. The annual report. The statute. The dataset. The interview transcript.

   Video cites by clipping. Thirty seconds of an interview means a full interview exists somewhere, often uploaded separately, often in an archive. Go get that. And when you cite a video yourself, link the timestamp — add &t= and the number of seconds — so the next person can check one sentence instead of watching an hour.

   This is the layer the rest of the guide exists to support, and it is the slowest. The chain is usually three or four hops and one of them is a dead link.

   What you’ll find down there The popular version is often off by a decade, an order of magnitude, or one word — and the original authors said something more careful and more interesting than the retelling.
5. 4

   Search like you’re hunting a document, not an answer

   Put exact phrases in quotes. Use site: to pin a domain — site:pitt.edu, site:gov. Use filetype:pdf when you want the actual report instead of eleven articles about the report. Add a year, or a range, when the thing you want is old.

   Then there is caption search. Internet Archive searches the closed captions of US television back to 2009, and C-SPAN’s library goes back to 1987 with clip links you can point at a single sentence. If somebody said it on television, it is text now and you can search it.

   When nothing works You have the wrong word, not the wrong tool. Go back to layer 2.
6. 5

   Ask somebody who already knows

   At some point the fastest route is a person. A subject librarian will find in ten minutes what you would hunt for in three hours, and that is the job, not a favor. The author of the paper will answer an email about the thing they have spent a career on. So will the retired engineer who ran the plant.

   There are also places built to hold that kind of answer. r/AskHistorians removes answers that are speculative, anecdotal or unsourced, and gives standing flair to people who repeatedly demonstrate expertise, which makes its long answers usable as bibliographies. Stack Exchange works the same way for technical questions. Specialist forums and Discord servers are where practitioners argue with each other, which is more informative than anywhere they explain themselves to outsiders.

   How to write the email One paragraph. Who you are, the single specific question, and what you have already read. People answer that. Nobody answers “can you tell me about your research.”
7. 6

   Go where the search box doesn’t reach

   Some of what you want was never indexed. Some was quietly changed after publication. Some sits behind a paywall your tuition already covers.

   Archived pages show you what a site said before somebody edited it. Library databases and newspaper archives cover the decades the open web never touched. Court dockets, agency filings and government reports are public and more readable than their reputation. Patents make an inventor explain the mechanism, by law.

   And a collection that was never digitized can still be read. Archives publish finding aids — a document listing what is in the boxes, box by box. Those are searchable, they are often the only evidence a collection exists, and you get at the boxes by making an appointment.

8. 7

   Check it before you repeat it

   Five questions, every time. Who is asserting this? How would they know? Who paid for it? When was it true? Is this the primary source, or someone’s summary of it?

   Date everything. Wrongness usually starts as a fact that was true once — and nothing about the sentence changes when it stops being true.

   Video is the hardest thing here to check, because you watched a person say it and that feels like testimony. It is a paraphrase with a face. Put it through the same five questions you would put a blog post through. And if a chatbot supplied the citation, open the citation: confirm the paper exists, the author is real, and the page says what you were told it says.

   If you only ever find one source, that is not a failure — say “one source claims” out loud when you report it. Stating how sure you are is part of the finding.

   Watch for the loop Four websites agreeing means nothing if all four are copying the same original. Follow each of them back; sometimes they collapse into one blog post from 2009.
9. 8

   Come back up with a five-minute version

   Say it out loud to another person: the question, the answer, your best source, the thing that surprised you, and the question you have now. If you cannot get through that in five minutes you are not finished reading. Get through it and you have a presentation, and that last line is where the discussion starts.
