To Remember, the Brain Must Actively Forget

“Researchers find evidence that neural systems actively remove memories, which suggests that forgetting may be the default mode of the brain.”

“Without forgetting, we would have no memory at all,” said Oliver Hardt, who studies memory and forgetting at McGill University in Montreal. If we remembered everything, he said, we would be completely inefficient because our brains would always be swamped with superfluous memories. “I believe that the brain acts as a promiscuous encoding device,” he said, noting that at night many people can recall even the most mundane events of their day in detail, but then they forget them in the following days or weeks.
