Indeed, there have been 3sigma deviations before (e.g. the diphoton resonance) which attracted a lot of attention and turned out to be nothing.

I'd encourage people to read up on the Look-elsewhere Effect when you see something like this:

I'm not saying this isn't potentially an interesting result, but 3sigma deviations when your parameter space is so large is actually not a big deal.

Unlike that 750 GeV lump, there are other observables in this case which build a consistent picture. Some fits to Wilson coefficients in b->sll were at almost 7σ even before this new result.

3 Sigma seems like it is very much worthy of more research, though not necessarily cause to say this is the new truth.
