Watch for
Nostalgic statements like "things were better when..." that ignore the full picture of the past.
Outcome & SelfBias #38
Declinism
The past always looks better than the present.
The predisposition to view the past more favourably and the future more negatively, believing that society or institutions are in decline despite evidence to the contrary.
Why it matters: Explains why every generation believes the next is "going downhill" despite consistent improvements in quality of life metrics.
Try this
Compare like-for-like data across time rather than comparing memories of the best of the past with the full range of the present.
Real-world example
Claiming music was better "back in the day" while ignoring the low-quality songs that have been forgotten and only the best have survived.

Psychological mechanism
Differential Memory Decay. The human mind acts as an emotional filter; memories of acute emotional distress, fear, and daily annoyances fade faster than generalized positive memories, leaving a rosy composite of the past that never actually existed.
Seminal research
Explored under memory architecture frameworks by Laura Carstensen (2005) regarding age-related shifts in memory processing and positivity bias.

Debrief
Biases are not character flaws. They are recurring patterns in how minds compress uncertainty, save energy, and narrate reality. Once you recognise the pattern, you can slow the decision down, test the assumption, and make space for a better explanation.
