Aphantasia Research Library
A personal research collection on aphantasia — the absence (or marked reduction) of voluntary visual mental imagery. Compiled by 8 parallel research agents on 2026-05-06, each covering one independent domain.
Roughly 25,000 words across 8 files, with ~250 cited sources.

Quick orientation
If you're newly exploring this, a sensible reading order:
- 01 — what aphantasia is and isn't (debunks the common misconceptions)
- 04 — take the VVIQ to see where you land on the spectrum
- 06 — read accounts from people whose phenomenology probably matches yours
- 08 — the cognitive implications you may have already noticed
- 02 + 03 — what's happening in the brain and what's new in research
- 05 — co-occurring conditions worth knowing about
- 07 — what (if anything) can be done
Headline findings worth knowing
- It's real and measurable. Pupillometry (Kay 2022) shows pupils don't dilate to imagined bright scenes in aphantasics — an objective marker independent of self-report.
- It's stable but not necessarily uniform. Voluntary vs involuntary imagery, object vs spatial, and modality (visual / auditory / motor / taste) can dissociate.
- You're not alone in surprising company. Pixar co-founder Ed Catmull, Disney animator Glen Keane, Firefox co-creator Blake Ross, and author Andy Weir all have aphantasia.
- It runs in families. ~10× elevated risk in first-degree relatives (Bainbridge group via Nature 2026).
- There may be an upside. Wicken / Keogh / Pearson 2021 found flatter physiological response to scary scenarios — a possible protective effect against intrusive imagery in PTSD.
- Counter-intuitive 2026 finding. "Hypophantasia" (very weak imagery) may correlate with worse mental-health outcomes than "core aphantasia" (no imagery at all).
- No validated treatment exists. Psychedelic case reports are the most striking but N≈2 published, and Pearson et al. (Cortex 2025) warn explicitly about irreversibility risks.
- Live debate. Whether decodable V1 patterns in aphantasic brains represent unconscious sub-threshold imagery (Pearson camp) or just perceptual residue (Cabbai / Phillips camp) is unresolved.

Notes on the collection
- Each file is self-contained with its own Sources section.
- Cross-cutting topics (e.g., SDAM appears in 05 and 08; Catmull in 06 and 03's Pixar / creativity context) are handled by deferring to the primary file as flagged in the agent briefs.
- A few sources behind paywalls or login walls (Blake Ross's original Facebook essay, ScienceDirect PDFs) were accessed via secondary aggregators or archives; flagged in the relevant files.
