If you're a regular listener to the 80,000 Hours Podcast you can sign up to be sent a short form asking for your feedback on each episode a few days after it comes out:

Obviously you don't need to respond to them all, just to the episodes you would have listened to or watched anyway.

We carefully read and think about all of your responses and use them to help with decisions about who to interview, about what topics, and how to approach the conversations. So thanks to those who've helped with this group over the years!
