And even that conventional criterion failed in the recent case of
faster-than-light neutrinos, where 6.2 sigma was briefly achieved,
This raises the question of whether seven sigma is any better. The
alleged Higgs boson so far hasn't done much better than the alleged
faster-than-light neutrinos, raising the possibility that we're
emotionally biased *against* FTL but *for* the Higgs boson.
Perhaps sigma is the wrong unit.
(Disclaimer: I've had exactly zero contact with Stephen Hawking on this.)
