Every claim, tied to
a real source.
A Deep Dive is only as good as what it reads. Here is how we choose the sources, weigh them, and make every claim checkable.
How we choose sources
For every topic we gather a wide pool of candidate material — videos, academic papers, long-form articles and transcripts — then evaluate each for relevance, credibility and recency before it earns a place in your dive. A typical dive draws on 50+ evaluated sources.
The kinds of sources we read
Video & lectures
Talks, courses and explainers — transcribed and timestamped so claims point to the exact moment.
Academic papers
Peer-reviewed research and preprints, weighted by venue and citation.
Long-form articles
Reporting and essays from credible publications and primary authors.
Interviews & transcripts
First-hand accounts and conversations, attributed to the speaker.
Our citation standard
Every factual claim in a Deep Dive carries a numbered citation that links to the source behind it. Where sources agree, we say so. Where they conflict, we show both and tell you which is stronger — never a single confident answer with nowhere to check it.
What we won’t do
- We don’t invent sources or quotes.
- We don’t hide where a claim came from.
- We don’t present one view as settled when the sources disagree.
For rights holders
Dives summarise, synthesise, and cite; they are not reproductions — we want readers clicking through to originals. If you believe a Deep Dive reproduces your work beyond fair synthesis and citation, or you want your attribution corrected, contact sources@speedlearning.com [TBD — confirm mailbox] with the dive topic, the material in question, and your relationship to it. Formal DMCA notices: [TBD — register a designated agent with the US Copyright Office and list the agent’s contact details here].
