What is the opposite of realism in quantum mechanics?

Click For Summary

Discussion Overview

The discussion revolves around the concept of realism in quantum mechanics and its opposite, exploring terminology and philosophical implications. Participants examine whether "anti-realism" or "non-realism" is appropriate in this context, and they delve into the implications of various interpretations and theories related to realism.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants suggest that "anti-realism" is the opposite of realism in quantum mechanics, while others propose "non-realism" as a more suitable term.
  • There is interest in the mathematical formalisms that define realism and how they can be tested or falsified.
  • One participant notes that the term "local realism" is tied to Bell's theorem and that relaxing the assumption of realism does not significantly alter the conclusions about nonlocality in quantum mechanics.
  • Another participant argues that realism implies the existence of properties independent of observation, while contextuality challenges this notion by suggesting that reality is dependent on specific contexts.
  • Some contributions highlight the confusion surrounding nonlocality and its distinction from locality, emphasizing that nonlocal correlations do not allow for signaling.
  • A participant mentions that many physicists hold both realist and materialist views, and discusses the orthogonality of locality and realism.
  • References to papers by Gisin are provided, discussing the nature of realism and its compatibility with quantum mechanics, particularly regarding measurement outcomes and randomness.

Areas of Agreement / Disagreement

Participants express a range of views on the terminology and implications of realism and its opposites, indicating that there is no consensus on the definitions or the philosophical interpretations of these concepts.

Contextual Notes

Some discussions point to the vagueness of terms like "local anti-realism" and "local non-realism," and the limitations in the literature regarding theories that relax criteria for realism. The conversation also touches on the dependence of definitions and the unresolved nature of certain philosophical questions in the context of quantum mechanics.

I'm sorry to say I don't know of any interesting up to date works on the subject. Contextualist theories are just beginning to establish themselves and the evidence is still pouring in at a brisk pace. Photosynthesis and animal navigation abilities that apparently can only be explained by room temperature entanglement for example. Physicists are rediscovering the world all over again and often feeling a bit humbled by it being oh so much more complex then they imagined as well as excited at the prospects. Not unlike the transition we went through from Newtonian mechanics to modern physics.

Ok, thanks, wuliheron. I've seen and think I've mentioned this sort of notion in other contexts ((:), but hadn't seen much applied in this one, too.

Yeah, it adds new meaning to "quantum weirdness" to assume they are contextual and forces people to re-evaluate their behavior in every context including classical ones.

Very fascinating thoughts, indeed!
