  The totalitarian principle establishes that `anything not forbidden is
compulsory'. The problem of quantum correlations is explaining what selects the
set of quantum correlations for a Bell and Kochen-Specker (KS) contextuality
scenario. Here, we show that two assumptions and a version of the totalitarian
principle lead to the quantum correlations. The assumptions are that there is a
non-empty set of correlations for any KS contextuality scenario and a
statistically independent realisation of any two KS experiments. The version of
the totalitarian principle says that any correlation not forbidden by these
assumptions can be produced. This paper contains a short version of the proof
[presented in {\em Phys. Rev. A} \textbf{100}, 032120 (2019)] and explores some
implications of the result.
  This article is part of the theme issue `Contextuality and probability in
quantum mechanics and beyond'.
