David is right. Converse (writing about the 1950s) and Lipmann (writing about the 1910s) described swing voters in similar terms. And I think the lesson now (as then) is that you don't win them over by writing the right policy position paper.

Now out in @science.org: misinformation exploits outrage to spread online. www.science.org/doi/10.1126/... Doing this work was way harder than it had to be, thanks to Big Tech. I want to highlight our lead analyst @killianmcloughlin.bsky.social for his heroic perseverance to bring you this paper 🧵
We tested a hypothesis that misinformation exploits outrage to spread online, examining generalizability across multiple platforms, time periods, and classifications of misinformation. Outrage is highly engaging and need not be accurate to achieve its communicative goals, making it an attractive signal to embed in misinformation. In eight studies that used US data from Facebook (1,063,298 links) and Twitter (44,529 tweets, 24,007 users) and two behavioral experiments (1475 participants), we show that (i) misinformation sources evoke more outrage than do trustworthy sources; (ii) outrage facilitates the sharing of misinformation at least as strongly as sharing of trustworthy news; and (iii) users are more willing to share outrage-evoking misinformation without reading it first. Consequently, outrage-evoking misinformation may be difficult to mitigate with interventions that assume users want to share accurate information.
