Model Uncertainty and Policy Choice:A Plea for Integrated Subjectivism
models decision theory subjectivism climate science economics policy
2016/6/13
A question at the intersection of scientific modeling and public choice is how to deal with uncertainty about model predictions. This "high-level" uncertainty is necessarily value-laden, and thus must...
Stem cells are defined by capacities for both self-renewal and differentiation. Many different entities satisfy this working definition. Explicating the stem cell concept reveals it to be relational a...
Distinguishing Risk and Uncertainty in Risk Assessments of Emerging Technologies
risk uncertainty carbon nanotubes real-world experiments deliberation decision theory precaution
2011/9/8
Economist Frank Knight drew a distinction between decisions under risk and decisions under uncertainty. Despite the significance of this distinction for decision theory, we argue that there has been i...
Ignorance, Uncertainty, and the Development of Scientific Language
values agnotology uncertainty value judgments science and values language concepts
2011/9/8
Robert Proctor has argued that ignorance or non-knowledge can be fruitfully divided into at least three categories: (1) ignorance as native state or starting point; (2) ignorance as lost realm or sele...
Uncertainty is a necessary condition for the sound moral and scientific conduct of research involving human subjects. If the expert scientific communities, medical or otherwise, lacked uncertainty abo...
VARIETIES OF POSSIBILITY: HOW ITERATED MODALITIES SOLVE A METHODOLOGICAL DILEMMA OF SIMULATING UNDER UNCERTAINTY
simulation climate change prediction limits of science
2009/3/25
This paper sketched a conceptual framework for expressing uncertain, possibilistic knowledge. A framework which allows to express our foreknow-ledge in a more nuanced way than simply by labelling some...
Photons uncertainty removes Einstein-Podolsky-Rosen paradox
Einstein-Podolsky-Rosen paradox locality
2008/4/22
Einstein, Podolsky and Rosen (EPR) argued that the
quantum-mechanical probabilistic description of physical reality
had to be incomplete, in order to avoid an instantaneous action
between distant m...
Non-collapse theories of quantum mechanics have the peculiar characteristic that, although their measurements produce definite results, their state vectors remain in a superposition of possible outcom...
In this paper I argue that two domains of uncertainty should inform our strategies for making social policy on new genetic technologies. The first is biological complexity, which includes both unknown...
Everettian accounts of quantum mechanics entail that people branch; every possible result of a measurement actually occurs, and I have one successor for each result. Is there room for probability in s...
Identity and uncertainty in Everett's multiverse
Everett many-worlds uncertainty probability identity branching
2008/4/14
In the current debate on the concept of probability in the Everett interpretation of quantum mechanics Saunders and Wallace argue for a notion of pre-measurement uncertainty whilst Greaves and Myrvold...
Heisenberg's uncertainty principle is usually taken to express a limitation of operational possibilities imposed by quantum mechanics. Here we demonstrate that the full content of this principle also ...
Correlation coefficients and Robertson-Schroedinger uncertainty relations
uncertainty relations correlation coefficients
2008/4/10
Calling the quantity; 2ΔAΔB/|<[A, B]>|, with non-zero denominator, the uncertainty product ratio or UPR for the pair of observables, (A, B), it is shown that any non-zero correlation coefficient betwe...
Complementarity and Uncertainty in Mach-Zehnder Interferometry and beyond
Complementarity principle uncertainty principle joint measurement
2008/4/10
A coherent account of the connections and contrasts between the principles of complementarity and uncertainty is developed starting from a survey of the various formalizations of these principles. The...
Branching and Uncertainty
Everett many worlds Branching
2008/4/10
Following Lewis, it is widely held that branching worlds differ in important ways from diverging worlds. There is, however, a simple and natural semantics under which ordinary sentences uttered in bra...
