About · Authorship and accuracy

Who writes this course, and how we check it.

Nobody here is a clinician. That makes “why believe any of this?” a fair question, and the answer isn't our qualifications — it's a process you can inspect.

Who wrote it

Nightshore is made in the United Kingdom, and the course is written by the Nightshore team. Jun Le, who founded it and wrote most of the course, is a software engineer — not a doctor, a therapist or a counsellor. We hold no clinical accreditation and claim none. So the course doesn't speak as a professional: it reports what the research found, names who found it, and says how strong that finding is — including when the honest answer is that nobody knows.

What this is not

Not therapy, not medical advice, not a diagnosis. The course will not tell you that you are an addict, because it is not in a position to. If porn use is costing you your job, your relationship or your safety, or if you are depressed, anxious or in crisis, see a doctor or a qualified therapist — the course's third lesson, if things get heavy, says the same.

How every claim is checked

Four things:

  1. A register, graded. The course cannot state anything that isn't in the evidence register: 68 claims, graded 31 well established, 28 mixed evidence, 8 anecdotal, 1 myth, each listing its sources by name. The register is live, so read it rather than trust these counts.
  2. A citation lock. Every DOI, PMID, PMCID and arXiv id in the register is resolved against Crossref, Europe PMC, arXiv and DataCite and pinned in scripts/claims_citations.lock.json; scripts/test_citation_lock.py fails our build if one cannot be resolved, or if the author, year, journal, volume or pages we print disagree with the record behind it.
  3. Ten claims we refuse to make — a blocklist beside the register, so a popular line can't arrive by accident. It bars porn rewiring your brain like cocaine, fried dopamine receptors, any reboot timeline (“90 days to rewire”), “porn causes ED” as a flat fact, retention boosting testosterone, and any moral claim about porn in our voice.
  4. Corrections, on request. In September 2026 a researcher wrote in because a page described his study without citing it: our renderer was cutting each source list at its first editor's note and dropping most of the papers. He was right. Every paper the register holds now reaches the page.

The course is free, needs no account and no email address, and keeps no streak or day count.

How to report an error

Email support@nightshore.app with the page and what you think is wrong. What happens next: we re-check the claim against the source. If we got it wrong we correct the page — or re-grade the claim, or cut it — and record what changed and when. If we think it's right, we write back and say why.
