alt Hacker NewsI'm not really sure what the hostility is about. That's an interesting study albeit small: 42 non-aphantasiacs and 18 self-diagnosed phantasiacs. If one really wanted to quibble I'm sure there are other possible confounding variables which could be involved in both pupil dilation and self-reported aphantasia. I'm not "blaming" neuroticism, I'm pointing out that these self-reporting surveys are subjective in a way that can be influenced by personality traits.
A lot of people here are insisting, with no evidence whatsoever, that a lot of other people are deluded, or are in it to make money, or for an ego boost, or to get pity, etc. ad nauseam ... so don't play dumb.
Aphantasia, hypophantasia, phantasia, and hyperfantasia are all real, per the evidence. Absolutely no evidence supports the contrary claim.
I won't respond further.
