Ignorance is generally pictured as an unwanted state of mind, and the act of willful ignorance may raise eyebrows. Yet people do not always want to know, demonstrating a lack of curiosity at odds with theories postulating a general need for certainty, ambiguity aversion, or the Bayesian principle of total evidence. We propose a regret theory of deliberate ignorance that covers both negative fee...

On a continuum that begins with risk and progresses through uncertainty, ignorance is the third, final, and most extreme state in the sequence. With risk and uncertainty, the possible future states of the world are known. With ri...

The choice of membership functions plays an essential role in the success of fuzzy systems. This is a complex problem due to the possible lack of knowledge when assigning punctual values as membership degrees. To face this handicap, we propose a methodology called Ignorance functions based Interval-Valued Fuzzy Decision Tree with genetic tuning, IIVFDT for short, which allows to improve the per...

In this paper, the possibility of modeling the phenomenon “pluralistic ignorance” from social psychology, using epistemic/doxastic logic, is investigated. It is shown that the straightforward formalization of pluralistic ignorance does not capture the phenomenon completely. What is needed in addition is an assumption about the interplay between different agents’ beliefs or an assumption about h...
