Welcome to the Saturday edition of The Conversation U.S.’s Daily newsletter.

In nine years of marriage, the biggest arguments my husband and I have had have been over politics. An article I edited this week helped me understand why: It’s because he’s wrong.

Or, at least, I think he is.

Behavioral scientists Andras Molnar, at the University of Michigan, and George Loewenstein, at Carnegie Mellon University, study the role of beliefs in politics and everyday life. Their new research shows that what frustrates us most isn’t disagreement itself but the conviction that the other person’s information is incorrect. For example, two people may disagree about how much immigration the country should allow. But if one of them insists immigrants commit more crime than people born in the U.S. – and the other cites data showing otherwise – the conflict stops being about policy or priorities and becomes about the other person being wrong.

Their story today helps explain why we sometimes avoid people who hold different beliefs, and why arguments about things such as policing, climate change, vaccines and capital punishment can feel so personal.

This week we also liked stories about what ancient tree fossils tell us about rapid warming, a Gilded Age millionaire with his own style of philanthropy, and ideas for taxing oil companies’ windfall profits.
