David Broockman is a political scientist at UC Berkeley who digs into one of democracy’s core questions: can political messages really change minds? He’s spent his career running careful studies of persuasion, from door-to-door conversations to the effects of cable news, and testing whether the confident claims of political consultants actually hold up.

In our conversation, David shares the path that brought him into political science and the “credibility revolution” that reshaped how researchers study politics. We talk about what persuasion looks like in practice, why it’s so hard to predict which messages will work, and what his research reveals about the gap between political insiders’ instincts and what actually moves the needle.

Lulu Miller has done a lot of things and done them very well. She is currently the co-host of Radiolab and its family-friendly spinoff, Terrestrials. She also co-created Invisibilia with Alix Spiegel and wrote the beautiful book, Why Fish Don't Exist. In our conversation, I try to learn Lulu's secrets when it comes it sharing science across media. I've been a fan of her work for a long time, so it was great to get to talk with her!

(If you're here as a Radiolab fan, you should also check out my chat with Latif Nasser a couple of years ago.)

In the show, I mentioned a run of letterpress prints I did inspired by Lulu's book. You can get a print for yourself here and learn more about how they were made. Any sales feed back into the podcast.

Joel Bervell recently graduated from medical school, which is when he gained fame as an influencer helping the public navigate good medical science. He’s out there breaking down myths about medicine, particularly shining a light on racial disparities in health and treatment. He recently won a Peabody award, consults with the White House, has given interviews on various media platforms, and has given talks all over. He hosts the podcast, The Dose. And he developed an animated children’s show for YouTube ("The Doctor is In").

So, I think it’s safe to say Joel knows a thing or two about reaching people with solid science content. I was happy I could catch him in between the 30 things he’s working on to learn more about his story and how he pulls all of this off. So let’s jump right into my chat with Joel Bervell.

Kicking off the 3rd season of Hot SciComm Summer is Adam Cole. Adam started at NPR’s Science Desk in 2011 where he started making short videos and radio pieces. In 2014, he launched the YouTube channel Skunk Bear with NPR, which was a venue for fun, quirky, visual forays into science stories big and small. After NPR, he did work for Vox, including their Netflix series, “The Mind, Explained” in 2019.

Most recently, Adam’s work came on my radar again because he’s one half of the new YouTube channel, Howtown. Fans of SciCommSummer will remember my very first guest back in 2022—Joss Fong. Well, Joss is the other half of Howtown. Together, they’ve been doing really excellent work building an independent channel making long-form videos exploring big questions and the methods scientists use to answer them. It’s so good. You need to check it out if you haven’t yet.

Adam shares his story as a science journalist, the makings of Howtown, the value of having a creative partner, and the pros and cons of working for yourself or a more established institution.

Watch Howtown (YouTube) and support their Patreon.
