Summary

Peer-reviewed study analyzing ~63,000 Reddit threads (r/UFO and r/UAP, 2014–2024) to test whether government uap-disclosure events reduce conspiratorial and disinformation narratives in online UFO communities. Using LLM-assisted content coding (Gemma 9B / Gemini 2.0 Flash) and cross-correlation time-series analysis against a 50+ event timeline, the authors find a statistically significant transparency-effect: official disclosures (congressional hearings, aaro reports, declassified documents) drive immediate Reddit activity focused on transparency and analysis, while conspiratorial content drops. The paper documents distinct cultures of the two subreddits — r/UAP emphasizes trust, government, and national security discourse, while r/UFO leans toward spirituality, paranormal belief, and entertainment. The study provides an extensive literature review of U.S. government UFO disinformation campaigns from the robertson-panel through project-blue-book to the Bennewitz Affair, framing these as confirmed conspiracy theories that justify community distrust.

Key Claims

  • Government disclosures produce a measurable transparency-effect — Reddit activity shifts toward disclosure/transparency discussion (CCF r = .10 at lag 0–1 day) while conspiratorial and debunking content is deemphasized (cross-correlation analysis)
  • The r/UFO subreddit (3.5M users) features more conspiracy theory, debunking, spirituality, and entertainment content than r/UAP (200K+ users), which focuses on trust, government, and national security (LLM topic classification)
  • 46% of r/UAP users also post on r/UFO; cross-posting users are disproportionately engaged with disclosure and conspiracy content (network analysis)
  • Historical U.S. intelligence disinformation campaigns (robertson-panel, AFOSI/richard-doty operations, majestic-12 forgeries) constitute confirmed conspiracy theories requiring academic reassessment of conspiracy-theory pathologization (Parker 2024, Brewer 2017, Pilkington 2010)
  • david-grusch’s whistleblower testimony and david-fravor’s uss-nimitz-uap-incident account are positioned as milestones in disclosure that shifted mainstream discourse (Lomas et al. 2025, Baio 2023)
  • jacques-vallee’s three-category “cover-up” framework (negative institutional attitudes, obfuscation, phenomenon’s own silencing capacity) remains relevant to understanding information suppression (Vallee 1975)
  • LLM-based qualitative coding of Reddit achieved Krippendorff’s alpha of .701 and Cohen’s kappa of 0.69 against human coders
  • Hector Quintanilla (last project-blue-book head) admitted USAF “routinely lied about UFO cases to protect classified programs” (Quintanilla 1974)

Notable Quotes

“The transparency effect driven by government disclosures effectively counters the erosion of trust fueled by conspiratorial narratives.” — Bastos & Duarte (abstract)

“US government disclosures about UAPs are significantly more likely to drive conversations and deliberation about disclosure (r = .10, lag = 0) and transparency (r = .10, lag = -1) than conspiratorial, debunking, or sightings content.” — Bastos & Duarte (results)

“The pathologization of [conspiracy] narratives can obscure legitimate critiques of institutional and government power, particularly when intelligence agencies, corporations, and political elites are the purveyors of conspiratorial slamming that later gained official acknowledgment.” — Bastos & Duarte (literature review)
