I wrote an essay during grad school about how learning the art of asking questions and the discipline of curiosity as a journalist helped me be a better person-in-relationship.
Addendum: the craft of accuracy and praxis of fact-checking does not necessarily help relationships. You can grill a source on what exact date it was and push them to remember the exact time of day, and confront them with an earlier story in which they said the opposite.
Do not attempt that practice with a partner.
