Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Simply not preparing i = 2 or i = 5 pairs makes hidden variables violate the Bell (and CHSH) inequality in half of all runs on average, showing that 'often' violation is uninteresting. → Vongehr 2012

q2 · i? · design · r1
Numerical result shown in Supplemental Material Fig. 4: hidden variables that set N2 and N5 to zero reach the equality in Eq.(3) on average, and random fluctuations violate the Bell and CHSH inequality "in half of all runs on average". The article presents this as a baseline making 50%-violation models uninteresting.
"The random fluctuations around the equality then violate the Bell (as well as the CHSH) inequality Eq.(3) in half of all runs on average ( Sup. Mat. Fig. 4 )."
