Have you ever been sure that you remember something from your past, only to have someone tell you that it never happened? If so, you may have experienced cryptomnesia—a memory delusion in which you mistakenly believe that a memory is real, despite evidence to the contrary. While cryptomnesia is relatively rare, it can be quite alarming when it happens. In this blog post, we’ll explore what cryptomnesia is, its causes and symptoms, and how to treat it. We’ll also discuss some famous cases of cryptomnesia and dispel some common myths about it. So if you’re curious about this little-known phenomenon, read on!
Cryptomnesia is a person’s belief that they are not recalling something that it actually had been. It can result from muscle memory, where some movement learned by repetition may become automatic and be forgotten over time. It was first suggested in 1874 by Stainton Moses (1), who studied hypnosis and how it could influence memory recall. Originally called “Retroactive Habituation” the term “cryptomnesia” later came afterward due to phonetic similarity with another word (pseudomnesia) which literally means false memory and describes an artificial or fictitious recollection of events experienced as true memories.
Is cryptomnesia dangerous?
Cryptomnesia can happen to anyone even the most focused introverts. The trick is that it only becomes dangerous if you just repeatedly forget what has happened to yourself or others. If you’re constantly forgetting your own memories, then it’s time to visit the doctor because something might be going on with your health.

Cryptomnesia is a rare form of memory disorder in which an idea that was previously used unconsciously to help create or remember new information becomes conscious. The person often realizes that they are remembering something familiar, but don’t remember the first time it happened. The sufferer may feel as though somebody else added this detail to their memory and start questioning the validity of what they thought were original thoughts. It happens most commonly when the sufferer has just absorbed new information and then engages in conversation about their recent experience, eg., after reading an article on art history, not recalling before going out that night that they had read this article earlier that same day.

What Is Cryptomnesia and How to Avoid ?
The definition of cryptomnesia is really broad and some people are using it interchangeably with plagiarism. For example, someone might take an idea from something they read and rather than credit the source you distorted or change it to make your work unique. Basically, when you can’t remember where you learned something but still use it (or forget to attribute). Cryptomnesia is not always intentional – often times this happens because of faulty human memory – but intentionally falsifying information is also included.
Many writers on the subject of cryptomnesia attribute memory lapses to absorption in writing and outlining, or the tendency to take too many drafts without referencing other work. Ever worry you’re plagiarizing an idea from a dream? Fear not! You’re probably just experiencing “cryptomnesia.” It’s basically our brain’s way of taking notes by merging memories with imagination during deep thought, according to Psychology Today. The basic idea behind cryptomnesia omissions is that we have ideas stored deep within our subconscious (probably because there are many avenues through which they could be reached).

The Causes of Cryptomnesia
Cryptomnesia is thought to happen when a person can’t recall any of the details about an event, but years down the line they are confronted by a similar experience. The neuro-scientific explanation for this phenomenon happens in regards to the “limbic system.” It’s believed that sometimes parts of our memories just vanish without us taking notice and new unassociated memories replace them. Through further study, they have still trying to understand how this occurs or if it’s even possible at all past understanding.
Cryptomnesia, which is also called misattributed memory (MA), is an unconscious form of plagiarism. It occurs when a person might struggle to recall information from their past and instead create new information that has the feeling of familiarity. It’s common for people under high amounts of pressure or stress to have cryptomnesia incidents because they are under more external stress as opposed to internal conscious stress.
The idea behind this is that it often takes less energy for our brains to rewrite something without making any changes than it does to create a completely new thing from scratch. Furthermore, studies have found that people with higher IQs are significantly more likely than those with lower IQs to commit cryptomnesia.
The Symptoms of Cryptomnesia
Cryptomnesia is a form of amnesia where the subject falsely remembers information to be true. It is caused when someone cannot think of an incident and experiences feelings or motivations associated with it, so they invent false details to fill in the gaps (such as specifying who was at a meeting instead of just saying that it was attended by most people).
It is a phenomenon in which a person falsely recalls memories of information contained in documents, conversations, or other media. The term was coined in 1874 by Stainton Moses. While cryptomnesia can be helpful at times (such as when one forgets how to spell words), it is usually undesirable and often leads to inaccuracies and mistakes.
