Fig. 3: Effects of the three-way interactions between the honesty scores of the seeds (FmB_s), the ideology of the repliers (I_score), and the party of the politicians who wrote the seeds (Party) on the honesty scores of the replies (FmB_r).

The estimates are derived from the regressions described in Equation (2) (see “Methods”). The figure is divided into two panels: the left-hand panel considers seeds written by Democrat politicians, whereas the right-hand panel focuses on seeds written by Republican politicians. The x-axes in both panels represent the FmB scores of the seeds. The y-axes in both panels show the FmB scores of the replies. In both cases, a value of FmB < 0 signals belief-speaking texts, whereas a value of FmB > 0 indicates fact-speaking texts. The I_score scoreline types and colors are assigned based on their relationship to the mean and standard deviation of I_score. A value of  −1 standard deviation from the mean is represented in blue, indicating repliers who tend toward more liberal views, whereas a value  +1 standard deviation from the mean is depicted in red, indicating repliers characterized by a more conservative partisanship.
