Particle physicists seem to constantly announce discoveries which then disappear. What is going on? How seriously are you to take the recently announced Fermilab muon g-2 anomaly or the B-meson anomaly at the Large Hadron Collider? In this video I explain what's going on.

I have a longer comment about the recent muon g-2 measurement here:

Addendum to what I say at 5 mins 30 seconds: That's only for a normal distribution. The relation between confidence level and standard deviation can differ for other distributions.
Correction to to what I say at 7 mins 18 seconds ("had no known interpretation"). This only refers to the superjets, not to the pentaquarks (which, well, were interpreted as pentaquarks). Sorry about that.
