It is well known that complete prior ignorance is not compatible with learning, at least in a coherent theory of (epistemic) uncertainty. What is less widely known, is that there is a state similar to full ignorance, that Walley calls near-ignorance, that permits learning to take place. In this paper we provide new and substantial evidence that also near-ignorance cannot be really regarded as a...

Engineers and scientists are increasingly required to design, test, and validate new complex systems in simulation environments and/or with limited experimental results due to international Epistemic Uncertainty Workshop, Sandia National Laboratories, Albuquerque, NM, August 6-7, 2002 © Ayyub 2002 2 and/or budgetary restrictions. Dealing with complex systems requires assessing knowledge and inf...

Purpose: The aim of this paper is to present, in an integrated manner, the knowledge acquired about pluralistic ignorance in the fields of social psychology, sociology and business. Particularly, to identify the factors that work as antecedents of pluralistic ignorance, as well as its consequences, in various research contexts.
