  We study here the dynamics of opinion formation in a society where we take
into account of the internally held beliefs and externally expressed opinions
of the individuals, which are not necessarily the same at all times. While
these two components can influence one another, their difference, both in
dynamics and in the steady state, poses interesting scenarios in terms of the
transition to consensus in the society and characterizations of such consensus.
Here we study this public and private opinion dynamics and the critical
behavior of the consensus forming transitions, using a kinetic exchange model.
