From Osher Doctorow

D. Bar of Bar-Ilan U. Israel and Karel V. (K. V.) Kuchar of U. Utah
may be considered arguably to have founded Probabilistic Quantum
Gravity, despite an onslaught so to speak of probability-
statistics-"stochastic" papers in arXiv since the early 1990s, and
despite possible disagreement by Bar (Kuchar's papers in arXiv stopped
in 2001, so I don't know if he's still alive although I think that he
was still giving a class or two at U. Utah until at least 2006).
Before I get into the topic of Bar's and Kuchar's papers and their
relationship to Probable Influence/Causation (PI), I'll briefly
indicate why an "onslaught" of papers in the probability-
statistics-"stochastic" fields seems to have produced so few
applications to Quantum Gravity.
Perhaps the most important reason is that Probability-
Statistics-"Stochastic" (Stochastic just means Probability)
researchers in pure or applied mathematics seem to have been self-
selected or perhaps even evolution-wise selected for one-track-
mindedness somewhat reminiscent of the way in which many physics
researchers believe that the Mainstream and "Past Research" and Peer
Review are the essence of Creative Genius (if these are the essence, I
wonder what the outer form looks like!). Researchers or even
students might like to look up "Compulsive-Obsessive" as keywords on
the internet, which roughly speaking describes one-track-minded people
who react outrageously to the slightest disruption of their routine
(if anybody has watched the "Monk" detective series on TV, that's the
same idea).
So if you look up keywords in arXiv or even Front for the Mathematics
ArXiv with "probability", "statistics", "stochastic" in them, you'll
typically get something like one of the following:
1) The relative frequency or limiting relative frequency school, also
called "frequentist".
2) The conditional probability or its subtype Bayesian probability-
statistics school.
3) The "quantum-is-related to nothing else" school.
4) The "cosmology is related to nothing else" or "0 vs 1" school.
5) The "discrete and nothing else" school.
6) The anti-probability-statistics school ("God does not play dice"
and its descendants/adherents)
7) The "one Max Born result but nothing else" school (in Schrodinger
equation).
8) The Independent Probability-Statistics school (roughly, nothing
causes anything else, or if does it's a mistake).
9) The "entropy and statistical thermodynamics/statistical mechanics
uber alles" school, also known as the information (more appropriately
disinformation) school.
I'll let readers look up some of the papers in these categories and
others, just adding here that "gravitational quantization" produces 21
papers, "quantum probability" produces 176 papers, "quantum
stochastics" produces 191 papers, "stochastic mechanics" produces 38
papers, "statistical thermodynamics" produces 91 papers in arXiv.
