Recall bias is bias caused by inaccurate or incomplete recollection of events by the respondent. It is a particular concern for retrospective survey questions.

Guidelines

How long is "too long" for recall?

It depends on the type of event respondents are being asked to recall. Research shows strong evidence of recall bias in food consumption, but little evidence for agricultural production. As a rule of thumb, 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).

How to avoid recall bias?

Useful strategies:

  1. Reduce recall periods as much as possible. For example, add follow-up surveys by phone, or personal diaries.
  2. Conduct focus groups to understand salience of the indicator in question, and gauge a reasonable recall period.
  3. When Piloting your Survey, carefully test recall periods; if possible try shorter and longer periods and check for differences in variance
