Evidence Dossier

Every consequential claim, rated and sourced. Statuses: Established · Strong · Moderate · Anecdotal · Unresolved · Unsupported · Contradicted. Last updated: 2026-08-23.

Ratings change only when the underlying evidence changes. Historical assessments are never silently rewritten — see corrections for the change history.

EV-001
DMT alters visual processing in the human brain.

Claimant: Mainstream neuroscience (multiple peer-reviewed studies)

Supporting: EEG-fMRI work (Timmermann et al., PNAS 2023, DOI 10.1073/pnas.2218949120) and a broad pharmacological literature on 5-HT2A agonism.

Counter/limits: None material; effects magnitude varies by dose and measure.

EstablishedTimmermann et al. 2023, PNAS
EV-002
Coherent laser light passing through a diffraction grating produces structured speckle/interference patterns.

Claimant: Classical optics

Supporting: Standard laser optics: coherent light through gratings and rough surfaces produces stable diffraction lattices and speckle.

Counter/limits: None.

EstablishedLaser diffraction / speckle literature (textbook physics)
EV-003
Some observers under DMT report code-like or glyph-like imagery when viewing the diffracted 650 nm lattice.

Claimant: Danny Goler; Veilbreak participant reports; pilot study

Supporting: Goler's IPI Letters News & Views report describes consistent descriptions of code-like structures; Veilbreak records many 'code observed' reports.

Counter/limits: Self-reported, unblinded, expectation-rich context; no objective record of the imagery.

Well documented observationallyGoler, IPI Letters (2025), DOI 10.59973/ipil.158
EV-004
Everyone who attempts the experiment sees the phenomenon.

Claimant: (implicit strong reading of project claims)

Supporting: Majority of Veilbreak experiments are marked 'observed'.

Counter/limits: Veilbreak also contains null results ('not observed'), including sober conditions; self-selection of reporters likely inflates positives.

ContradictedVeilbreak null-result records
EV-005
Different observers see exactly identical symbols.

Claimant: Strong version of Goler's claim; The Discovery promotional claims

Supporting: Project statements assert recurring, consistent forms across participants.

Counter/limits: No publicly auditable participant-level dataset demonstrates exact same-symbol correspondence between blinded independent observers. Goler himself has framed Vision Pro research as an attempt to determine whether exact correspondence exists (2026).

Not demonstratedShawn Ryan Show #320 (July 9, 2026)
EV-006
Reported symbols occupy identical spatial coordinates across observers.

Claimant: Documentary/project claims

Supporting: Promotional materials describe same characters in same positions.

Counter/limits: Vision Pro experiment explicitly aims to test this; no public blinded cross-subject coordinate dataset exists.

Not demonstratedThe Discovery project claims
EV-007
The reported glyphs contain objective information (a transmissible message).

Claimant: Interpretation associated with the project

Supporting: Subjective reports of 'reading' structured forms.

Counter/limits: No decoding, prediction, or information-transfer test has succeeded publicly; identical-information tests have not been run at controlled standard.

Not demonstrated
EV-008
The experiment proves we live in a simulation.

Claimant: Popular framing (media, promotion)

Supporting: None beyond interpretation of subjective reports.

Counter/limits: Even full confirmation of shared percepts would not establish a computational substrate; multiple mundane hypotheses remain open.

UnsupportedVice coverage framing (Jan 28 2025) — example of popular framing, not support
EV-009
The IPI Letters paper is a peer-reviewed scientific proof of the phenomenon.

Claimant: —

Supporting: Paper exists with DOI 10.59973/ipil.158, published 8 Jan 2025, reporting >1,000 participants.

Counter/limits: IPI Letters categorizes it as 'News and Views'; the journal's own rules identify News and Views as non-peer-reviewed. No participant-level public dataset supports reconstructing the >1,000-participant figure.

Contradicted (as stated); paper itself is genuine but non-peer-reviewedIPI Letters article page — section: News and Views
EV-010
DMT can cause symbol-like forms to emerge from ordinary laser speckle (optical/perceptual hypothesis).

Claimant: At least one Veilbreak participant; several independent commentators

Supporting: Consistent with known speckle physics + psychedelic pattern-completion; some participants explicitly interpreted their experience this way.

Counter/limits: Does not by itself explain reports of high-information glyph structure without priming.
