Is Ignorance Bliss?
ignorance is bliss, 'tis folly to be wise. " Thomas Gray If ignorance were bliss, there is information you would pay not to have. Hence the question is whether a rationally-behaving agent would ever do such a thing. This paper demonstrates that 1. A Bayesian agent with a proper, countably additive prior never maximizes utility by paying not to see cost-free data. 2. The definition of " cost-fre...
متن کاملWhen Ignorance is Bliss
It is commonly-accepted wisdom that more information is better, and that information should never be ignored. Here we argue, using both a Bayesian and a non-Bayesian analysis, that in some situations you are better off ignoring information if your uncertainty is represented by a set of probability measures. These include situations in which the information is relevant for the prediction task at...
متن کاملIgnorance is bliss: the information malleability effect
In this dissertation, I propose that, post-action, people tend to be more optimistic about outcomes when their actions were based on malleable (vague) information compared to when their actions were based on unmalleable (precise) information. However, pre-action, no such difference occurs. I term this inconsistency in optimism in the pre and post-action stage, the Information Malleability Effec...
متن کاملIgnorance is bliss: general and robust cancellation of decoherence via no-knowledge quantum feedback.
A "no-knowledge" measurement of an open quantum system yields no information about any system observable; it only returns noise input from the environment. Surprisingly, performing such a no-knowledge measurement can be advantageous. We prove that a system undergoing no-knowledge monitoring has reversible noise, which can be canceled by directly feeding back the measurement signal. We show how ...
متن کاملPhonetic ignorance is bliss: Inves phonetic information reduction o
Perception studies have long argued that phonetic confusions are more likely to happen across some phonetic features than other (e.g., place of articulation rather than manner) [1]. Similarly, we and others have noted that pronunciation variation occurs more frequently in unstressed syllables, and in syllable codas. This suggests that a phonetic information structure is at play, where for decod...
