" Polarization is not the only phenomenon of “groupthink” that can influence the hearts and minds of individuals when they get together.4 Other studies have shown that compared to individuals, groups tend to be more dogmatic, better able to justify irrational actions, more likely to see their actions as highly moral, and more apt to form stereotypical views of outsiders. In addition, when strong-willed people lead group discussions, they can pressure others into conforming, can encourage self-censorship, and can create an illusion of unanimity. "
