Erfahren and herausfinden can both result in someone learning information. Erfahren emphasizes that the information becomes known through a notification or message, whereas herausfinden highlights the person's own search, questions, or thinking. When someone informs you, erfahren is the right word; when you determine the answer yourself, herausfinden is the right word.
