Much research shows that judgmental estimation could be improved by combining estimates from independent judges as well as within judges. These results have been obtained mostly with judgments about matters of fact, that is, for which there are objective truth criteria. In the present research, we extend these findings to performance evaluations. In a controlled field study, expert judges provided evaluations of a large number of essays written b…
False Negotiations
The usual purpose of negotiations is to explore options and reach an agreement, if possible. We investigated a notable exception to this generalization, where a party negotiates without any intention of reaching an agreement. False negotiation occurs when a party gains more by stalling the negotiations until an external change takes place that improves its position considerably. While false negotiators aim to avoid agreement within the current fr…
When guessing what another person would say is better than giving your own opinion
Exploiting the Wisdom of Others to Make Better Decisions
Although decision makers often consult other people's opinions to improve their decisions, they fail to do so optimally. One main obstacle to incorporating others' opinions efficiently is one's own opinion. We theorize that decision makers could improve their performance by suspending their own judgment. In three studies, participants used others' opinions to estimate uncertain quantities (the caloric value of foods). In the full‐view condition, …
Agency and the construction of social preference
The term social preference refers to decision makers' satisfaction with their own outcomes and those attained by comparable others. The present research was inspired by what appears to be a discrepancy in the literature on social preferences--specifically, between a class of studies demonstrating people's concern with inequality and others documenting their motivation to increase social welfare. The authors propose a theoretical framework to acco…
Decision Framing and Support for Concessions in the Israeli-Palestinian Conflict
The purpose of the study is to explore, in the context of the Israeli-Palestinian conflict, the influence of framing a decision task as inclusion or exclusion on Israeli Jewish respondents' support for the concession of Jewish settlements in the West Bank and Gaza. Respondents received a list of 40 Jewish settlements. Details such as the number of residents and geographical location were provided for each settlement. The respondents were randomly…

Receiving other people’s advice
Combining advice
We present two studies that evaluate how people combine advice and how they respond to outlying opinions. In a preliminary study, we found that individuals use discounting strategies when they encounter an extreme opinion in a small sample of opinions taken only once (a one‐shot advice‐taking situation). The main study examines the influence of outlying opinions (which may or may not be accurate) within a learning paradigm with feedback. This stu…

Advice Taking in Decision Making
Elimination and Inclusion Procedures in Judgment
Consider two judgment procedures for selecting an answer from a set of multiple alternatives. One could answer a question either by including likely alternatives from the initial set of alternatives or by eliminating the least likely alternatives from that same initial set. An interesting question is whether the two judgment processes are equivalent and yield the same final selection. The results from two studies indicate that individuals generat…
Inferring accuracy for judges and items
This study explores the relationship between the precision and the accuracy of forecasts using either judge or item as the unit of analysis. Participants in five experiments answered general-knowledge questions by indicating intervals that were likely to include the correct answer. Results indicate that the precision of an interval estimate is not a straightforward cue to the likelihood that such an interval includes the truth (hit rate). Whereas…
Precision and accuracy of judgmental estimation
Whereas probabilistic calibration has been a central normative concept of accuracy in previous research on interval estimates, we suggest here that normative approaches for the evaluation of judgmental estimates should consider the communicative interaction between the individuals who produce the judgments and those who receive or use them for making decisions. We analyze precision and error in judgment and consider the role of the accuracy–infor…
A case study of expert judgment
In this case study of economists' forecasts concerning economic downturn, we examine key issues concerning the psychology of prediction and the controversy surrounding the value of expertise in forecasting. We examine when experts' knowledge promotes forecast accuracy and whether biases found in psychological studies (including underutilization of relevant base rates and tendencies to extreme prediction) occur in these economic forecasts. Experts…
Measures of discrimination skill in probabilistic judgment
People's ability to assess probabilities of various events has been the topic of much interest in the areas of judgment, prediction, decision making, and memory. The evaluation of probabilistic judgments, however, raises interesting logical questions as to what it means to be agood judge. In this article, we focus on a normative concept of probabilistic accuracy that we call discrimination and present a measure of a judge's discrimination skill. …
