Major upheavals in society can be terrifying. They can also be hard to track through one lifetime, so history provides a map for the types of scenarios that lead to big change. Things like increased poverty, war, and distrust in the government have led to more crime and political radicalization. Understanding history and what drives change helps protect people from conspiracy theories, which tend to spread faster during stressful, chaotic times. When unchecked, belief in conspiracy theories can have tragic consequences and lead to real-world violence.
