Memory helps us make sense of our past, but it is prone to error, distortion, and retrospective bias. Some studies have shown that our recollection of our past political views can be distorted by our present political beliefs. Many studies have shown that inaccurate memories are often expressed as unshakable beliefs about the past.
Implicit prejudices, biases, assumptions, and blind spots influence our decisions and our actions. We cannot help but distort the past, because memory is not an archival recording and is constantly reinvented by exposure to new learning. The conscious mind does not accurately reflect the process whereby we come to a decision or an opinion.
