Michel Davier stated that there is only a 1 in 40,000 chance that the observed difference between the Muon g-2 experimental result and the theoretical prediction is due to statistical chance.
Notes on verification
The statistical figure (1 in 40,000 ~ 4.2 sigma) is well-corroborated by Fermilab and physics press sources describing the 2021 Muon g-2 announcement. However, the specific attribution of this quote to Michel Davier could not be independently verified beyond the CNRS article, so confidence in the exact quote/attribution is moderate rather than high.
