In this paper we aim to quantify the capability of the correlation function of galaxy cluster to constrain the intrinsic scatter $\\sigma_{\\ln M}$. We demonstrate how the linear bias measured in the correlation function of clusters can be used to determine the value of this parameter. The new method is tested in simulations of a $5, 000 deg^2$ optical survey up to $z \\sim 1$, similar to the ongoing Dark Energy Survey (DES).
