Concept
Rosy retrospection
Summary
Rosy retrospection refers to the psychological phenomenon of people sometimes judging the past disproportionately more positively than they judge the present. The Romans occasionally referred to this phenomenon with the Latin phrase "memoria praeteritorum bonorum", which translates into English roughly as "memory of good things having passed". Rosy retrospection is very closely related to the concept of nostalgia. The difference between the terms is that rosy retrospection could be understood as a cognitive bias, whereas the broader phenomenon of nostalgia is not usually seen as based on a biased perspective.
Although rosy retrospection is a cognitive bias, which distorts a person's view of reality to some extent, some people theorize that it may in part serve a useful purpose in increasing self-esteem and a person's overall sense of well-being. For example, Terence Mitchell and Leigh Thompson mention this possibility in a chapter entitled "A Theory of Temporal Adjustments of the Evaluation of Events" in a book of collected research reports from various authors entitled "Advances in Managerial Cognition and Organizational Information Processing".
Simplifications and exaggerations of memories (such as occurs in rosy retrospection) may also make it easier for people's brains to store long-term memories, as removing details may reduce the burden of those memories on the brain and make the brain require fewer neural connections to form and engrain memories. Mnemonics, psychological chunking, and subconscious distortions of memories may in part serve a similar purpose: memory compression by way of simplification. Data compression in computers works on similar principles: compression algorithms tend to either (1) remove unnecessary details from data or (2) reframe the details in a simpler way from which the data can subsequently be reconstructed as needed, or (3) both. Much the same can be said of human memories and the human brain's own process of memorization.
