Thanks to the 5,975 people who took the 2025 Astral Codex Ten survey.

I’ll be publishing more complicated analyses over the course of the next year, hopefully starting later this month. If you want to scoop me, or investigate the data yourself, you can download the answers of the 5500 people who agreed to have their responses shared publicly. Out of concern for anonymity, the public dataset will exclude or bin certain questions2. If you want more complete information, email me and explain why, and I’ll probably send it to you.

You can download the public data here as an Excel or CSV file:
