Telescoping

Definition

A memory error in which respondents misplace events in time, typically drawing incidents from outside the reference period into it (forward telescoping), leading to over-counting of recent crime. Forward telescoping is the more common direction.

Field
Victimisation surveys / memory research
Error type
Misplacing events in time
Common direction
Forward telescoping (events pulled into the reference period)
Effect
Over-counting of recent crime

Common questions

Why is forward telescoping more common than backward telescoping?+

Recent, salient events feel psychologically closer than they actually are, so respondents tend to recall an incident that happened before the survey's reference window as if it occurred within it, inflating counts for the recent period more often than events are mistakenly pushed backward out of it.

How do survey designers reduce telescoping error?+

Common techniques include bounding interviews, where a respondent's answers from a prior survey wave are used to flag and exclude previously reported incidents, and using landmark or event-anchored questions that help respondents place incidents more accurately in time.
