His 2023 essay in The Atlantic describes his journey from studying social media to creating dialogue networks, and his 2024 Atlantic essay explores ways to tackle truth decay. Roy’s widely viewed TED talk Birth of a Word presents his pioneering research on his son’s language development that led to new ideas in media analytics.
