Unethical amnesia is the tendency for humans to forget the dishonest actions they committed, or to remember them in a blurred or very limited way. While people tends to remember the immoral actions of others with precision, they tend to remember their own similar actions less easily. [1] This phenomenon is thought to help maintain self-esteem and limit bad conscience or fear of punishment. [2] [3] The phenomenon has been studied by Harvard University in the US, and by the CNRS in France.
