User: Is there a scientific explanation for the phenomenon of déjà vu?
Assistant: Yes, there is a scientific explanation for the phenomenon of déjà vu. Déjà vu occurs when a person has a strong feeling of familiarity for something, even when it is actually not yet experienced. It is believed that the phenomenon is caused by a mismatch between short term and long term memory. This can be due to a delay in the transfer of information from short-term to long-term memory, or a misattribution of the memory to a previous experience.
