Fig 3. Pearson correlation coefficient between public and private opinions.

Results for different q-panel sizes are presented: (a) q = 4, (b) q = 5 and (c) q = 6. Analytical results are marked by lines. Symbols illustrate outcomes from Monte Carlo simulations: △ for the TA (think then act) and • for the AT (act then think) models. The system starts its evolution from the ordered state for all cases. We can see that the states of opinions on public and private levels are more strongly correlated in the TA model. On the other hand, for small values of the independence level, the correlation coefficient stays close to zero in a wider range of independence variability for the AT model. Note that in the high-independence phase, our measure of association increases to 1 for the TA model whereas it decreases to 0 in the case of the AT model. Results from Monte Carlo simulations have been obtained for the system of the size N = 10⁶ after 10³ MCS.
