The "truth" and "reality" categories are particularly destructive landmines, as without a shared understanding of the world there can be no communication, therefore violent conflict is inevitable. It feels like these mental weapons are being deliberately deployed across the population, and the old ways of reconciling differences don't work any more. During the Trump presidency it felt like the population of the US was split in two different realities, and that the worldview of someone from the other side was completely alien. It works similarly in smaller scales as well, with things such as conspiracy theories.
