Received  January 2020 Revised  August 2020 Published  November 2020

Alternative proofs for the superadditivity and the affinity (in the large system limit) of the usual and some fractional Fisher informations of a probability density of many variables are provided. They are consequences of the fact that such informations can be interpreted as quantum kinetic energies.

Keywords: Fisher information, de Finetti's theorem, statistical mechanics, mean-field limits.
