Personal accounts preserve what a participant remembers from a particular position. Several witnesses can describe the same event differently because they saw different parts of it and had different access to information. Comparing the points they share and the points on which they disagree helps reconstruct what happened. Each account also needs to be weighed against the witness's role and opportunity to know about the decisions involved. Treating any one recollection as a complete account obscures those limits.

Participants' memories become more useful when compared with other accounts and tested against what each witness could have known.
