Error caused by inaccurate or incomplete recollection of events. A particular concern for retrospective survey questions.
Read First
- Lower salience and longer recall periods increase forgetfulness [1]
- How long is "too long" for a recall period for a survey question? It depends on the type of event: infrequent events (e.g. purchases of major assets) will be memorable for longer periods of time than routine events (e.g. use of public transportation).
Guidelines
How to avoid?
Useful strategies:
- Where possible, use methods to reduce recall periods for key indicators. For example, more frequent follow-up surveys by phone, or personal diaries
- When Piloting your Survey, carefully test different recall periods; if possible try shorter and longer periods and check for differences in variance
