Editing Bell's theorem (section)

===Superdeterminism===
{{Main|Superdeterminism}}
A necessary assumption to derive Bell's theorem is that the hidden variables are not correlated with the measurement settings. This assumption has been justified on the grounds that the experimenter has "[[free will]]" to choose the settings, and that it is necessary to do science in the first place. A (hypothetical) theory where the choice of measurement is necessarily correlated with the system being measured is known as ''superdeterministic''.<ref name=larsson14/>

A few advocates of deterministic models have not given up on local hidden variables. For example, [[Gerard 't Hooft]] has argued that superdeterminism cannot be dismissed.<ref>{{cite book |last='t Hooft |first=Gerard |author-link=Gerard 't Hooft |title=The Cellular Automaton Interpretation of Quantum Mechanics |volume=185 |publisher=Springer |year=2016 |doi=10.1007/978-3-319-41285-6 |isbn=978-3-319-41284-9 |oclc=951761277 |series=Fundamental Theories of Physics |s2cid=7779840 |url=http://www.oapen.org/search?identifier=1002003 |access-date=2020-08-27 |archive-date=2021-12-29 |archive-url=https://web.archive.org/web/20211229062338/https://library.oapen.org/handle/20.500.12657/27994 |url-status=live }}</ref>
