The role of prior knowledge and missing information in multiattribute evaluation

Article Abstract:

The degree to which people possess information does not necessarily indicate a correspondence with the confidence and intensity of decisions made. A study proves that individuals can make judgments on another's attitudes, regardless of the amount of information they possess about that person. The same applies for perceptions of attributes of inanimate objects. Although people with lower prior knowledge cannot easily identify and overcome misinformation, those with higher prior knowledge can detect misinformation and act accordingly when presented with a lack of information.

Contextual influences on judgment based on limited information

Article Abstract:

Contextual factors hasten judgment by increasing decision maker's sensitivity to the lack of weight of a given evidence. This sensitivity relatively increases judgmental moderation when assessment differs from object's descriptive attributes and when object is differentiated by a huge amount of attributes. Overall, the amount and type of information on the context factor largely affect the weighting and valuation of evidence on objects with limited information.

Weighting and trimming: heuristics for aggregating judgments under uncertainty

Article Abstract:

Weighting and trimming heuristics in compiling judgments under uncertainty increase accuracy of estimation. Computer simulation tests these heuristics over normative and cognitive schemes of the compiling process where the decision maker is faced with conflicting opinions and uncertainties. Results suggest cognitive weighting and trimming heuristics as vital in compounding people's opinion.
