Measures of lineup fairness: Do they postdict identification accuracy?

For non-choosers, decision time did not postdict accuracy.

A third question which has been the major theme in the investigation of estimator variables, is how well these variables postdict accuracy.

Response latency may be a useful and simple way to postdict eyewitness accuracy for people who choose suspects from lineups.

Did Herbert Fröhlich predict or postdict the isotope effect in superconductors?

However, when these postdictors are combined, two measures could be combined to postdict eyewitness accuracy: decision time and lineup fairness.

For improvements in the ability to postdict accuracy, research should aim to find factors that compliment the predictive utility of decision time, such as lineup fairness.

Because time must be measured before any feedback could be given, feedback could not reduce the ability of time to postdict accuracy.

Because these measures are made after the fact, lineup fairness would be an estimator variable in this case, and could be used to postdict eyewitness accuracy.

On the other hand, such evidence probably exists in many cases and finding methods to postdict the accuracy of such decisions could be extremely useful at the investigative stage even if never presented in court.

However, to the extent that the legal system will continue to rely on estimator variables, research in the area should focus on finding variables that can postdict accuracy independently of measures of decision time.
