Sources

Every number here has an origin.

This is the page that makes the rest of the site worth trusting. Below is each major claim, traced to the study, report, or record it came from — including notes on where the evidence is strong and where it’s still contested.

Youth & exposure

Common Sense Media (2023)

  • “Teens and Pornography.” Nationally representative survey of 1,358 U.S. teens aged 13–17. Source of the age-12 average, the 15%-by-age-10 figure, the 73% exposure figure, and the finding that a majority encountered aggressive content. commonsensemedia.org
  • Peter, J. & Valkenburg, P. M. “Adolescents and Pornography: A Review of 20 Years of Research.” Journal of Sex Research (2016). Basis for the associations with gender-stereotyped beliefs, earlier sexual debut, and aggression. Note: largely observational.
Women & the industry

Documented cases & analysis

  • “French Bukkake” case — French authorities indicted multiple men for rape, human trafficking, and aggravated pimping tied to pornography production (Le Monde / The Guardian, 2023).
  • Traffickinghub campaign & New York Times reporting (Kristof, 2020) documenting child sexual abuse material and non-consensual content on a major platform; led Visa, Mastercard, and Discover to suspend transactions and prompted government investigations in Canada and elsewhere.
  • U.S. federal definition of sex trafficking (force, fraud, or coercion) — basis for the “no list” point that coerced performance is trafficking by law.
  • Contested: The “#1 venue for trafficking” claim derives from National Human Trafficking Hotline calls/reports, which represent suspicions reported, not confirmed cases. We present it as a signal, not a count.
Men & health

Erectile dysfunction & problematic use

  • De Win, G. et al. “Associations Between Online Pornography Consumption and Sexual Dysfunction in Young Men.” JMIR Public Health and Surveillance (2021), n=3,419, ages 18–35. Source of the ~21% ED figure and the 27.7% vs 18.9% habituation figures. Key finding: problematic use — not porn use by itself — was associated with ED. publichealth.jmir.org
  • Park, B. Y. et al. “Is Internet Pornography Causing Sexual Dysfunctions? A Review with Clinical Reports.” Behavioral Sciences (2016). Basis for the rise in dysfunction among men under 40. Note: review including case reports.
  • Counter-evidence: Some studies (e.g., Prause & Pfaus) find no direct link, and an integrative review notes much evidence is cross-sectional and cannot establish causation. Cited on the page for honesty.
Marriage

Pornography use & divorce

  • Perry, S. L. & Schleifer, C. “Till Porn Do Us Part? A Longitudinal Examination of Pornography Use and Divorce.” Journal of Sex Research (2017). Three-wave GSS panel data; beginning use roughly doubled divorce probability (OR 2.19), holding for both sexes. pubmed.ncbi.nlm.nih.gov
  • Zitzman, S. T. & Butler, M. H. (2009) on hidden use and deception as an attachment threat in marriage.
  • Context: Reviews note the broader literature contains positive, negative, and null findings, and effects vary by gender, solo vs shared use, and initial marital happiness.
Our citation policy If a claim can’t be traced to a study, a court record, or a government report, it doesn’t go on this site. Where evidence is observational, we say so — observational research shows patterns but cannot prove cause and effect. Where a popular statistic is weaker than commonly claimed, we flag it rather than repeat it. Full citations with DOIs can be added as this library grows.
