“Over the past few decades, liberals and conservatives have been migrating into moral enclaves,” Motyl said. “They rarely communicate or have close relationships with people with different moral values.”

Similarly, polarized media provides a ready-made place for people to hear their worldview reinforced, Ditto told LiveScience.

“These places make money when people fight, and they’re not going to make money when people cooperate,” Ditto said. He suggested “breaking out of the media cocoon” to listen to how the other side frames issues.

When it comes time to actually talk face-to-face with someone on the other side of the political spectrum (Thanksgiving dinner, anyone?), Ditto recommends asking questions rather than arguing. Arguing, he said, tends to entrench people in their own positions. We convince ourselves that our beliefs are based on logic, when in fact, Ditto said, a great deal of our moral decisions are emotional.
