If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

Quantum Limits of Knowledge 2021

Wednesday 31st March, 2021

QBism (Quantum Bayesianism or Quantum Bettabilitarianism) has an instrumentalist, and therefore anti-realist, ancestry. Yet, it accommodates a non-conventional form of realism that still has to be assessed. Christopher Fuchs calls it "participatory realism". It is a form of realism for someone who cannot be dissociated from the "reality" she explores. Here, I explore several features and consequences of "participatory realism". I first connect it with the archetypal definition of "anti-realism" by Michael Dummett. I then explore the atypical connection between "reality" and theoretical symbolisms it involves: in "participatory realism", representationalism is discarded, and normativism is advocated instead. I finally compare "participatory realism" with other alternative forms of realism, such as relational realism.
