Overview of sentiment scores and their changes before and after different treatments. (a) Scatter plot of score changes for ten selected personages (i.e., TE, CC, CHC, EWH, CG, WW, MC, IN, QSH, XY, details are introduced in SI Appendix, Section 5) before and after exposure to positive (red) and negative (blue) content. The frequency distribution illustrates the distribution of score changes under positive and negative treatments. (b) Average sentiment scores across participants and personages before and after exposure to polarized content (positive and negative). Positive treatment significantly increases personage scores (p=0.046), while negative treatment significantly decreases them (p=2.35e-5). (c) Average sentiment scores across participants and distractors before and after exposure to positive and negative content. Distractors refer to entities that do not contain any relevant videos in the field study. Neither treatment significantly impacts distractor scores.
