Abstract

In a recent paper published in PNAS authors prove that locality and free choice are equivalent resources which need to be relaxed in order to fully reproduce some statistics in Bell experiments (while always maintaining realism). We explain that their assumption of free choice is simply counterfactual definiteness or noncontextuality. Therefore the resource in Bell experiments is contextuality and not the violations of locality and/or of free choice. It is definitely less mind boggling conclusion because experimenters` freedom of choice is a prerequisite of science,
