The source text confirms Scott Alexander's association with Astral Codex Ten as author (evident from the page header, copyright notice, and Substack attribution). However, the source does not contain any information about when he started writing the blog. The claimed startDate of 2013 is unverifiable from this source alone. The record is partially confirmed (person, org, and role are correct) but the startDate cannot be verified.
