I had stated all philosophical issues [pragmatism* aside] are reducible to the Philosophical Realism vs the anti-Philosophical_Realism dichotomy.
* It is contentious but I believe pragmatism is also anti-Philosophical_Realist, however I do not have sufficient stuff to justify for it at present.
Einstein's position is that of the Philosophical Realist, which I believe you are Carroll are.
Show me how is you realism different from that of Philosophical Realism;
Gladly. I'm not just going to show how it's different, I'm going to focus on how the specific difference is actually the focus of bells theorem.
First, we'll start where many layman's research starts on any topic: on Wikipedia.
https://en.m.wikipedia.org/wiki/Bell%27s_theorem
I'm so pleased that the internet has aligned such that my central point is in the first sentence:
Bell's theorem is a term encompassing a number of closely related results in physics, all of which determine that quantum mechanics is incompatible with local hidden-variable theories given some basic assumptions about the nature of measurement.
LOCAL HIDDEN VARIABLES
That's specifically what Einstein believed in. That's specifically his point of contention with quantum mechanics, and that's specifically the flavour of realism disproved by bells theorem.
So, what does local hidden variables mean? Unfortunately Wikipedia doesn't do a great job of specifying it, but it generally means this (and be prepared for a bit of dejavu, because we've been here before):
Local hidden variables is the idea, in quantum mechanics, that when you measure a property of a quantum entity (I love this word choice of yours and I've adopted it, thank you for that), that you are simply finding out something about the entity that was true the whole time, as opposed to standard quantum mechanics which says prior to measurement, the property did not have a single definite value.
As discussed many pages back, the focus here is on PROPERTIES, rather than the existence of things.
If I open up an envelope and find a red letter inside, it's natural for me to assume that there was a red letter inside that envelope all the way back in time to the point where the person who sent me the envelope put the red letter in. When I open the letter, I'm finding out something that was always true about the contents of the envelope.
Quantum mechanics says that quantum particles are not like envelopes in this way. When you measure, say, the spin of a photon as up and the spin of its entangled sister photon as down, you cannot say "this property we are just finding out about now, but the spin for each particle had that value the whole time."
Einstein believed in local hidden variables. Sean Carroll does not. I do not.
Of note is this paragraph on the Wikipedia page:
Copenhagen-type interpretations generally take the violation of Bell inequalities as grounds to reject the assumption often called counterfactual definiteness or "realism", which is not necessarily the same as abandoning realism in a broader philosophical sense.[77][78] For example, Roland Omnès argues for the rejection of hidden variables and concludes that "quantum mechanics is probably as realistic as any theory of its scope and maturity ever will be."[79]: 531
I like to highlight my OP in this case is ultimately to support my anti-realist position within the realist vs anti-realist debate.
From there to support my human-based-FSK, thus human-based-moral-FSK and so, moral facts which are Objective, therefore, Morality is Objective.
I think I quoted this somewhere;
" Given this contrast, one might expect
Carroll and Smolin to emphasize very different things in their books.
Yet the books mirror each other, down to chapters that present the same quantum demonstrations and the same quantum parables.
Carroll and Smolin both agree on the facts of quantum theory, and both gesture toward the same historical signposts.
Both [Carroll and Smolin] consider themselves realists,
in the tradition of Albert Einstein."

Even though Carroll may reject hidden variables, Carroll fundamental belief is still that of realism, i.e. Philosophical Realism, which is the same as held by Einstein.
On the other hand, Bohr's fundamental belief is that of
anti-realism, i.e. anti-Philosophical Realism;
The objective of this article is to demonstrate how the historical debate between
materialism and
idealism, in the field of Philosophy, extends, in new clothes, to the field of Quantum Physics characterized by
realism and
anti-realism.
For this, we opted for a debate, also historical,
between the
realism of Albert Einstein, for whom reality exists regardless of the existence of the knowing subject,
and [
anti-realism]
Niels Bohr, for whom we do not have access to the ultimate reality of the matter, unless
conditioning it to the existence of an observer endowed with rationality, position adopted in the Interpretation of Complementarity (1927) – posture that was expanded in 1935 when Bohr assumed a “relationalist” conception, according to which the quantum state is defined by the relationship between the quantum object and the entire measuring device.

From the above,
Those who believe in Philosophical Realism like you and Carroll will insist that Objective Reality exists independent of the human conditions as applicable to QM matters.
On the other hand, re QM matters, the Anti-Philosophical_Realists like Bohr and myself believe that reality is interdependent with the human conditions.
This meant that QM principles are conditioned to the human-based-QM-FSK.
My basic principle is this;
All facts, truths and reality are conditioned upon a specific human-based-FSK.
Thus QM facts, truths and reality are conditioned upon a specific human-based-QM-FSK.
This is the anti-Philosophical_Realism view.
In contrast, the Philosophical Realist like Carroll and you [not Einstein] would believe the following;
All facts, truths and reality are NOT conditioned upon a specific human-based-FSK, i.e. they are independent of the human conditions.
Thus QM facts, truths and reality [even though obey the Wave Collapse Function] ultimately are NOT conditioned upon a specific human-based-QM-FSK.
Within the P_Realist vs Anti-P_Realist debate;
I content that the P_Realist view [Bottom-Up] is grounded on an illusion and infected with a
Reality-Gap that by default cannot be closed at all.
The basic reference to this is Kant's assertion of the illusory noumenon and thing-in-itself.
The reason for the creation of this
Reality-Gap is due to psychology arising from an existential crisis.
Meanwhile the Anti-P_Realist is most realistic from the Top-Down [Kant's Copernican Revolution], i.e. empirically based plus philosophical-rational reasonings.
I suggest you get more familiar with the fundamentals of the P_Realist vs Anti-P_Realist debate, else we will be talking pass each other all the time.
