  In Phys. Rev. Lett. 113, 120404 (2014) [arXiv:1403.2362], Ferrie and Combes
claim that weak values could be a statistical artifact caused by correlations
between the disturbance and the post-selection condition imposed on the output.
In this comment, we show that the disturbance caused by a weak measurement is
sufficiently low to definitely rule out the model proposed by Ferrie and
Combes.
