This research determined the extent of judgment achievement (i.e., accuracy) across different decision-making domains (e.g., medicine, business, education, psychology). Judgment achievement was examined in terms of the lens model equation (Tucker, 1964). A meta-analysis of 29 studies incorporating 1,032 people across 43 judgment tasks was performed. Overall judgment achievement across different tasks was found to be moderate (r = .42), ranging from .22 for studies in the area of psychology to .58 for those in other professional areas. Methodological moderator factors (type of correlation, database) used in task analysis or the number of cues used in tasks were also considered. The findings indicated that research on judgment achievement should examine judgment tasks relating to specific research areas. © 2009 by Verlag Hans Huber.
