# Open Questions in Agent Selection > This open-questions register lists what we do not yet know about agent selection: for each question, the evidence we have, the evidence we are missing, and whether it is open, being investigated, or answered. This is a register of the questions about agent selection we have not yet answered. Each entry states why the question matters, the evidence we already have, the evidence we are still missing, and a status: open, being investigated, or answered. It doubles as a preregistration: when the [Research Lab](/research/) sets out to answer one of these, the question and its method are on the record here first. Where a question is already answered, we link the page that answers it.
