How common is aphantasia? Prevalence and research figures
Reliable figures from current research — from global population to regional data, from the spectrum to genetics.
For decades, aphantasia was treated as a curious one-off — today we know that about 1 % of people have it under a strict definition, up to roughly 4 % under broader definitions. Worldwide, that's roughly 80–320 million, depending on definition. This page summarizes the reliable figures from current research.

The imagery spectrum
Aphantasia is a spectrum — from complete absence of imagery to extremely vivid mental images.
Aphantasia
~1 %
Hypophantasia
~3 %
Average
~90 %
Hyperphantasia
~6 %
Where do these numbers come from?
The most reliable estimates come from Wright et al. (2024, Frontiers in Psychology, n=9,063) — the largest prevalence study to date — and Dance et al. (2022, Consciousness and Cognition, n=1,004). Both use the VVIQ, but apply different cut-offs:
- Strict (VVIQ = 16 of 80, Wright et al. 2024): ≈1 % of population
- Broader (VVIQ ≤ 32, Dance et al. 2022): ≈3.9 %
- Hypophantasia (VVIQ 17–32, Wright et al. 2024): ≈3.3 %
The 1–4 % range isn't uncertainty — it's a question of where the definition threshold is drawn. The Aphantasia Network's community survey (n > 14,000) offers additional self-selected data but is not a peer-reviewed study, so its figures aren't included above.

Differences between men and women
The largest peer-reviewed studies find no meaningful gender difference in aphantasia prevalence. Dance et al. (2022) reported no gender bias, and Milton et al. (2021) likewise found no significant difference (χ² = 3.98, p = .136). Claims of a specific percentage gap between men and women are not supported by the peer-reviewed literature.
Family clusters — hint at genetics
Aphantasia runs in families, pointing to a genetic component.
(Zeman et al., 2020)
Aphantasia runs in families — first-degree relatives of someone with aphantasia are more likely to also have it (Zeman et al. 2020, Cortex). That points to a genetic component, though a precise, robustly published clustering factor doesn't yet exist. Which genes are involved is not yet conclusively known as of 2026 — candidates include genes related to connectivity between visual cortex and frontal lobe.
Spectrum, not switch
Aphantasia is not a yes/no state but a spectrum. The VVIQ scale ranges from 16 (complete absence of imagery) to 80 (extremely vivid images). About 1 % are at the very low end under a strict definition (up to ~4 % more broadly, aphantasia), about 6 % at the high end (hyperphantasia, Wright et al. 2024), the rest distributed in between. Someone with a VVIQ of 24–35 ("markedly below average") doesn't have "mild aphantasia" — they simply have less vivid mental images than average.
~1–4 % isn't uncertainty — it's a threshold question
Different numbers in different studies don't come from researcher uncertainty. They come from different VVIQ cutoff values including different populations.
With a strict cutoff (VVIQ = 16) it's ~1 % (Wright 2024). With the common definition (VVIQ ≤ 32) it's ~3.9 % (Dance 2022). For everyday purposes, ~4 % (incl. hypophantasia) is a reliable guide value.
- VVIQ = 16: strict definition — ~1 % (Wright 2024)
- VVIQ ≤ 32: common definition — ~3.9 % (Dance 2022)
Frequently Asked Questions
Is aphantasia equally common in children and adults?
Likely yes. Aphantasia is congenital in most cases, so prevalence stays constant over life. It has been hard to study in children because the VVIQ requires verbal reflection from age 12+.
Are there countries or cultures with more/less aphantasia?
Current studies show no relevant regional differences. Prevalence in the US, UK, Germany, Australia, and Japan is comparable. This supports a biological rather than cultural basis.
How many people don't know they have aphantasia?
Self-report estimates suggest over half of affected people discover aphantasia only after age 25. Many lived decades assuming "imagine that" was metaphorical for everyone.
Is there a connection to specific talents?
A study with a self-selected sample found an association between aphantasia and technical-mathematical professions and software development (Zeman et al. 2020, Cortex). Whether that reflects a real overrepresentation, a causal effect (less visual distraction when coding), or selection (jobs that work without mental images) is an open question — and the sample bias means the finding shouldn't be overstated.
Where are you on the spectrum?
Take the VST-16 in 5 minutes and find out if you are among the ~1–4 % (methodology modeled on the VVIQ, Marks 1973).
