Dogmatism manifests in lowered information search under uncertainty

Search and Choice under Uncertainty

This thesis presents and analyzes the result of experiments including small decision problems. In the experiments, subjects are asked to choose one of two alternatives for a few thousand times. Two experiments are conducted. First experiment, where payoff structure is clearly told, is carried out in order to explore choice under uncertainty by examining whether expected utility theory holds or ...

Planning Information Gathering Under Uncertainty

We describe a decision-theoretic approach to information gathering from a distributed network of uncertain information sources. Our approach uses an explicit representation of the user’s decision model and a database of responsiveness information about information sources in order to plan and execute information gathering actions. The information gathering planner issues requests based on the v...

Search for Choquet-optimal paths under uncertainty

Choquet expected utility (CEU) is one of the most sophisticated decision criteria used in decision theory under uncertainty. It provides a generalisation of expected utility enhancing both descriptive and prescriptive possibilities. In this paper, we investigate the use of CEU for path-planning under uncertainty with a special focus on robust solutions. We first recall the main features of the ...

Sequential Search and Selection Problem Under Uncertainty

This paper formulates and discusses a series of sequential decision problems of the following common structure: A decision alternative of multiple attributes-that is, a job, an employee, or an investment alternative-is to be selected within a certain fixed length of time. An unknown number of alternatives are presented sequentially, either deterministically or in a random manner. The decision m...
