SOCIAL MEDIA DOESN’T just drive countries down the democratic ladder. It also heightens the ethnic, social, religious, and geographic divisions that can be the first step in the creation of factions. This is, of course, because myth, emotion, and the politics of grievance—all of which drive factionalism—make for incredibly engaging content. Social media algorithms encourage this divisive content. They segregate people by design, driving those whose values or opinions differ into ever-diverging realities, tearing societies apart.
