Knowledge, calibration, and resolution: a linear model
Article Abstract:
The 1977 results of a study by Lichtenstein and Fischhoff on the relationships between knowledge, calibration and resolution are debunked by a new study. Comparison and contrast of individual and group study results show that knowledge positively affects resolution and calibration, but that only the former expresses a distinct relationship with knowledge. The study further proves that knowledge, calibration and resolution are personal characteristics that change between individuals. Group composition, research procedures and tabulated results are discussed.

Outcome feedback effects on under- and overconfident judgments (general knowledge tasks)
Article Abstract:
The influence of outcome feedback on judgments of confidence in general knowledge tasks is investigated. Outcome feedback is theorized to have a twofold effect, namely, corrective and confidence increasing. Experiments show that outcome feedback reduces bias and improves calibration of underconfident judgments if items are nonindependent and related. Differences between with- and without-feedback groups on the dependent variables are found to be nonsignificant.

Judgment by outcomes: why is it interesting? A reply to Hershey and Baron: "Judgment by outcomes: when is it justified?" (response to J.C. Hershey and J. Baron, Organizational Behavior and Human Decision Processes, vol. 53, p. 89)
Article Abstract:
The response to the evaluation of a study on judgment by outcomes is presented. Judgment by outcomes is considered invalid because outcomes cannot be used as the basis of decisions. Bad decisions can also result into favorable outcomes while good decisions can result into unfavorable outcomes. The provision of identical information for decision makers and judges is also said to be unnecessary for decision making.
