Physicists Still Split on What Quantum Mechanics Means for Reality | Keith King
Physicists Still Split on What Quantum Mechanics Means for Reality Introduction Quantum mechanics is one of the most successful and experimentally verified theories in science, underpinning technologies from semiconductors to MRI scanners. Yet more than a century after its birth, physicists remain deeply divided over what the theory actually says about the nature of reality, according to a new Nature survey of over 1,000 researchers. Key Details Mathematical Success vs. Philosophical Disagreement • The equations of quantum mechanics reliably describe how particles behave at microscopic scales. • The disagreement lies in interpretation — what those mathematical wavefunctions actually represent in the physical world. Contrasting Views from Leading Physicists • Anton Zeilinger (University of Vienna): “There is no quantum world” — quantum states describe information in the observer’s mind, not an objective physical reality. • Alain Aspect (University of Paris-Saclay, 2022 Nobel Laureate): Disagrees, asserting that quantum states do reflect something real in nature. Survey Findings • More than 1,000 physicists from diverse fields were polled, revealing no consensus on fundamental questions such as: • Is the wavefunction real or just a tool for predictions? • Does quantum mechanics imply determinism, randomness, or something else entirely? • How should paradoxes like wavefunction collapse and entanglement be understood? Why It Matters These philosophical divides shape how scientists design experiments, interpret results, and envision the future of quantum technologies. The lack of consensus suggests that even as quantum mechanics drives practical innovation, its deeper meaning remains one of science’s most enduring and profound mysteries.

Jan R. BoehnkeInvestigating functioning of the #EQ5D -Y-5L in five countries shows that participants can differentiate ordinal response levels, but that measurement quality and scaling functions differ by country and age:

Since this is conceptually similar to violations of invariance in other measurement models, I wonder whether the #utility #valuation literature needs a more formal framework for this and whether #Psychometrics might help with this?

This #CostUtilityAnalysis of 'academic detailing' to enhance naloxone distribution for opioid users (i) shows it potentially cost-effective at WTP of US$50,000 per #QALY and (ii) it used #UtilityScores developed from #NIDA shared data*

* To develop these we used National Institute on Drug Abuse-published #RCT data

Enhancing Naloxone Distribution for Opioid Users in the USA: A Cost-Utility Analysis of Academic Detailing to Clinicians - Applied Health Economics and Health Policy
Background Opioid overdose remains a leading cause of mortality in the USA. Although distributing naloxone to laypersons for use during witnessed opioid overdoses has been shown to effectively reduce overdose deaths, clinician awareness of naloxone prescribing remains low. Academic detailing (AD) has been reported to be an effective strategy to increase naloxone distribution to individuals at risk of opioid-related overdose/death. Objective This study evaluated the cost effectiveness of an academic detailing program aimed at promoting naloxone prescribing for adults at risk of opioid-related overdose compared to no intervention (non-AD program). Methods A Markov model with an integrated decision tree was developed to estimate the costs and outcomes associated with the AD program over a lifetime horizon from the US payer perspective. Model robustness was tested using sensitivity and scenario analyses. Results The results indicated that the AD program incurred a total direct cost of US$6280 and achieved 16.52 quality-adjusted life years (QALYs). In comparison, the non-AD program incurred a total direct cost of US$5971 and achieved 15.92 QALYs. The incremental cost-effectiveness ratio for the AD program was US$514 per QALY gained with an incremental net monetary benefit of US$29,739. Sensitivity and scenario analyses confirmed the robustness of these findings, which suggest that AD is a cost-effective strategy for improving survival and quality of life in individuals at risk of opioid overdose. Conclusions For decision makers seeking to address the opioid crisis, implementing an academic detailing program represents a cost-effective option at a willingness-to-pay threshold of US$50,000 per QALY gained.
