<br>
They may depend on how they are interacted with - including the<br>
specific means of measurement - to the same extent as if you knew the<br>
original state.<br>
<br>
But excluding those factors, they don't. One particle is in one<br>
state, and will remain in that state unless and until interacted with.<br>
The other particle is likewise in the other state.<br>
<br>

<br>
And don't have to. See the above point on, "This doesn't violate...".<br>
<br>

It does not.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">How would you describe the difference between "determinism" and "superdeterminism?"</div><div dir="auto"><br></div><div dir="auto">From all your writings on superdeterminism, you never seem to suggest any difference between the two.
