Confabulation is a symptom of various memory disorders in which made-up stories fill in any gaps in memory.
German psychiatrist Karl Bonhoeffer coined the term “confabulation” in 1900. He used it to describe when a person gives false answers or answers that sound fantastical or made up.
While this condition may at first sound like lying, confabulation only occurs when you have a condition that affects your memory. This is why confabulation is often described as “honestly lying.”
Someone with confabulation has memory loss that affects their higher reasoning. They subconsciously create stories as a way to conceal their memory loss. They aren’t aware that they aren’t telling the truth. They don’t have any doubt about the things they are saying, even if those around them know the story is untrue.
