A critical look at popular ‘retrocausation’ claims. Do they hold up?

In this publication, I address popular uses of the term 'retrocausation' in connection with quantum theory, and find that there is much that needs to be corrected and clarified. Much of the discussion in the literature on this topic involves inconsistencies and equivocation about what retrocausation really is, and about what it can do.  In … Continue reading A critical look at popular ‘retrocausation’ claims.

Why “making sense of quantum theory” by denying that theories are about the world does not really work

This post points out a little-known but powerful and important argument from Joe Henson regarding a proposed interpretation of quantum theory known as "Qbism". Qbism is currently advocated primarily by Fuchs, Mermin, and Schack. Henson's argument discloses a crucial fallacy in Qbism's claim to demonstrate that quantum mechanics is a local theory, where a 'local' … Continue reading Why “making sense of quantum theory” by denying that theories are about the world does not really work

Is There Really “Retrocausation” in Time-Symmetric Approaches to Quantum Mechanics?

This is a preprint version of this paper: AIP Conference Proceedings 1841, 020002 (2017) R. E. Kastner Abstract. Time-symmetric interpretations of quantum theory are often presented as featuring "retrocausal" effects in addition to the usual forward notion of causation. This paper examines the ontological implications of certain time- symmetric theories, and finds that no dynamical notion … Continue reading Is There Really “Retrocausation” in Time-Symmetric Approaches to Quantum Mechanics?
