PATTERNS OF FORGETTING AND TELESCOPING: An Analysis of LEAA Survey Victimization Data

The research reported in this article sought to estimate the feasibility of measuring patterns of forgetting and forward telescoping in victimization survey data. It was suggested that if these two sources of memory bias could be accurately and reliably measured, victimization survey data could be adjusted to produce improved estimates of both the amount of crime and of changes in the crime rate over time. Examination of the data suggests that the likelihood of developing a general model for correcting mnemonic biases is very low. ll?is conclusion follows from: (I) evidence indicating differential victimization survey recall across reported and unreported crime events; (2) the apparent dissimilarities of telescoping/forgetting patterns across samples and seasons; and (3) the lack of a stable comparison estimate of the “true” distribution of incidents with which to calibrate a correction model.
