Watch for
Being unsure whether an event happened weeks or months ago.
Memory & AttentionBias #75
Telescoping Effect
We misplace events in time.
The tendency to perceive recent events as farther back in time or older events as more recent than they actually are distorting the temporal distance.
Why it matters: Well-documented in survey research where respondents misremember when events occurred.
Try this
Use a calendar or timestamp rather than relying on temporal intuition.
Real-world example
Feeling like a vacation from three months ago happened much longer ago or like a meeting from last week happened yesterday.
Key researchers
Norman Bradburn
First described in 1987
Psychological mechanism
Temporal reconstruction errors. Without precise temporal tags the brain estimates time based on memory vividness and contextual cues which are imperfect proxies.
Seminal research
Norman M. Bradburn, Lance J. Rips, and Steven K. Shevell (1987), "Answering autobiographical questions: The impact of memory and inference on surveys."

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.
