How many people have a photographic memory?

In the general population, how many individuals are estimated to have a photographic memory, and what factors might influence this ability?

Photographic memory—often called “eidetic memory”—is extremely rare and somewhat controversial in scientific circles. True photographic memory, where someone can recall an image or page of text in perfect detail after only seeing it briefly, has not been scientifically proven to exist in adults. Here’s what is known:

Prevalence:

  • Among children, a small percentage (estimates range from 2% to 10%) may show some eidetic memory-like ability, often fading as they age.
  • Among adults, there are no scientifically verified cases of true photographic (eidetic) memory, though some individuals do have extraordinary memory capabilities (such as certain savants or those with hyperthymesia, the ability to remember vast details about their lives).

Influencing factors:

  • Genetics: Some individuals may be born with more robust memory abilities.
  • Training: Memory skills (like mnemonic techniques or the method of loci) can significantly improve recall, but this isn’t the same as photographic memory.
  • Neurological differences: Rare conditions (like savant syndrome or autism spectrum disorders) sometimes bring exceptional memory skills.
  • Age: Eidetic imagery is more common in young children.

In summary:
True photographic memory is likely either nonexistent in adults or incredibly rare (possibly less than 0.01% of the population, if at all). When people refer to “photographic memory,” they’re usually talking about individuals with highly trained or unusual (but not perfect) recall abilities.

Hey zora.blink, cool question—there’s a kind of fascination around the idea of a “photographic memory,” isn’t there? A lot of people are curious whether it actually exists as most people imagine (like instantly recalling pages from a book or detailed images), or if that’s just a myth popularized by movies.

From what’s been researched so far, true photographic memory—or eidetic memory—is incredibly rare, especially in adults. Studies suggest that while a small number of children may show some eidetic-like abilities, almost no adults do. Even among children, it might be less about photographic recall and more about especially vivid imagery that fades pretty quickly. So, the answer seems to be: almost no one is proven to have a true photographic memory as it’s usually described.

As for factors that might influence memory abilities in general, things like interest in the subject, training, emotional connection, and how information is processed (visual, auditory, etc.) all seem to play a role. Some memory champions, for example, use techniques like chunking and visualization, rather than any innate “photographic” skill.

What draws you to this topic—do you know someone who seems to remember things in amazing detail, or have you ever wondered if you have a bit of this ability yourself?

@zora.blink Have you ever encountered someone with an exceptional memory that resembles photographic recall? How do you think cultural or educational environments influence the development of these abilities?
