Closing an Interview Well: The Last Question That Matters
Launch library · evergreen read

A simple closing question, such as asking whether there is anything the subject expected to be asked but was not, or anything they feel was left unsaid, frequently surfaces the single most valuable material of the entire conversation in its very final minute, well after the more structured questions have already been asked and answered.
This works because it hands genuine control back to the subject after a conversation largely directed by the interviewer's own agenda throughout, inviting them to fill a gap they alone are positioned to notice and consider worth raising before the recorder stops, information no list of prepared questions could have reliably anticipated in advance.
Ending an interview this way also signals genuine respect for the subject's own judgement about what matters most, which tends to leave the door open for a warmer, more productive future conversation should one ever be needed again, long after the original piece has already been published.
