No, no such thing is. It doesn't matter if you go by strict/maximum<br>
superdeterminism or my "superdeterminism lite": neither theory<br>

<br>
Problem is, "fool us" means there is conscious intent. That's the<br>
standard definition: "fool" here is a verb, therefore, something is<br>
doing the action upon "us", the noun, and "fool" involves conscious<br>
intent by definition.<br>

It's the definition of "fool us", not the definition of<br>
"superdeterminism", that's causing the issue here.<br></blockquote><div><br></div><div>Do you understand why "fool us" is the most appropriate verb to describe what must be involved in a superdeterministic universe?

Are you saying that superdeterminism is a many-world theory? I<br>
thought that the former was explicitly not, and is an alternative to,<br>
the latter set.<br></blockquote><div><br></div><div>Full many-worlds (in contast to the "semi-many-worlds" other theories) says that the branches continue to exist after a conscious measurement.

It just (like all the others) assumes other branches stop existing after a measurement is made.</div><div><br></div><div>Normally superdeterminism is put forward only as a means to explain Bell inequalities, and usually it is silent on conventional/standard QM ideas like the two-slit experiment, so I don't know how a usual superdeterministic would explain the mirror photon and its interference effects.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

No such anticipation is needed. Conditions can be set up so that if a<br>
human brain (or the alternatives) does its thing later, the results<br>
will be in a certain way, but that does not require anticipation of<br>
any specific actor doing that exact thing.<br></blockquote><div><br></div><div>If you still insist on this, I have to conclude that you do not understand the consequences of Bell's Theorem ( <a href="https://en.wikipedia.org/wiki/Bell%27s_theorem">https://en.wikipedia.org/wiki/Bell%27s_theorem</a> ) as they relate to the experiment.</div><div><br></div><div>There is simply no way that an entangled photon (in a single state (not a superposition of multiple simultaneous states)) can carry enough information with it (from the time it is first created) to know to disagree with its partner photon 75% of the time, when the polarizing filters are offset by 120 degrees, and to agree with its partner photon 100% of the time when the polarizing filters are aligned.</div><div><br></div><div>This is what is meant when all physicists agree that single, local, hidden variables have been disproven.

It's like if I produce weighted dice, that will almost always come out<br>
with a 1 and a 6. If a later observer comes along, sees the dice,<br>
declares that they must be fair and independent, and keeps rolling<br>
7...I did not specifically anticipate that, or any, observer. Nor did<br>
I arrange to make a fool out of that particular observer. That<br>
observer may have been born after I made those dice - indeed, possibly<br>
after I forgot all about them, migrated off of Earth (supposing the<br>
observer is born on Earth), et cetera. I have no animus toward nor<br>
knowledge of that observer. So, to say that I specifically made those<br>
dice to make a fool of that observer is demonstrably incorrect. Nor<br>
did I produce any sign saying that these dice are fair; the only one<br>
assuming they ever were fair is that observer.<br></blockquote><div><br></div><div>Bell's inequality violation is stranger than weighted dice. Weighted dice can be easily explained mechanistically.

Some things just are, with no "how" or "why" - at least, none that we<br>

How is it that radioactive decay follows a logarithmic spread rather<br>
than linear? Why is it that, if half the particles in a sample decay<br>
in time X, only half of the rest will decay in a further interval of<br>
time X? If the particles are independent of one another, how do the<br>
undecayed particles know that half of their kin have decayed so they<br>
should have a lower chance of decaying? (The answer may have<br>
something to do with survivor's bias, but that doesn't explain how<br>
they got on a logarithmic spread in the first place.)<br></blockquote><div><br></div><div>You can explain logarithmic decay without reference to other radioactive particles.</div><div><br></div><div>Model any single nucleus as having some fixed "D%" probability of decaying over some length of time L, for any D, and any L.</div><div><br></div><div>Now model some population of these particles.
