The confidence-accuracy (C-A) relation for general knowledge (GK) and eyewitness memory (EM) was compared in both within-and between-subjects analyses. Researchers in the cognitive tradition tend to use within-subjects designs and to find moderately positive C-A relations, whereas those in the forensic tradition tend to use between-subjects designs and to find no relation. Eighty subjects took part in one of two conditions-EM or GK. No difference between conditions was found on the

There was a strong positive C-A correlation (r = .58, p < .01) for GK but not for EM (r = -.11, ns). One source of this difference may be the differing opportunities for calibration offered by the two kinds of memory.
