Cryptomnesia

Cryptomnesia operates by disrupting the normal memory retrieval process. When individuals retrieve information, they should ideally recall its context and source. However, in cryptomnesia, the retrieval is partial or flawed—contextual details or the original source are not correctly recalled, making the information appear novel. Memory reinforcement after the fact can solidify these incorrect associations, leading to the conviction that the ideas are original.

• An author might draft a story believing it to be entirely new, when, unbeknownst to them, it closely resembles a book they read years ago.
• A songwriter could create a melody, genuinely believing it to be original, only to realize later it closely mirrors a tune they've heard before.
• A person might recount 'their' innovative solution to a problem, unaware that they had learned this solution in a forgotten workshop.

Critics of cryptomnesia suggest that its interpretations often rely on subjective judgments regarding the originality of actions or ideas, making it difficult to empirically study. Some argue that cryptomnesia might be a convenient explanation for alleged instances of plagiarism or intellectual theft without clear evidence. Moreover, its identification can sometimes lead to unnecessary self-censorship, stifling creativity under the fear of unintentional imitation.
