🎺 Call for proposals 🎺 1️⃣ replicate an existing experiment 2️⃣ run a novel experiment on repdata.com 3️⃣ coauthor with Mary McGrath and me to meta-analyze the replications and existing studies 4️⃣ publish your study details: alexandercoppock.com/replication_... applications open Feb 1 please repost! - 🌍🇺🇸 Published Today in PNAS Nexus 🌍🇺🇸 How can we foster collective climate action? - led by @dgoldwert.bsky.social, @smconstantino.bsky.social & @madalina.bsky.social - 17 behavioral interventions, designed by 50 experts - tested on >30000 US participants academic.oup.com/pnasnexus/ar... 🧵 1/11
- Teams of social and behavioral scientists were tasked with designing brief, scalable interventions intended to increase public, political, and financial climate advocacy. What can we share with study participants in less than 5 minutes to induce the most positive behavioral changes? 2/11
- For example, my team designed an interactive quiz intended to correct misperceptions about climate risks. Based on expert evaluations, this was actually predicted to be the most effective intervention. How did this work out in practice? 3/11

View full threadThis tracks well with heterogeneity analyses from a study with @miriamsorace.bsky.social, Tom Robinson & @simonhix.bsky.social: there, those who were less supportive of climate action to begin with were also less persuaded by nano-targeted climate policy proposals. 11/11 bsky.app/profile/miri...
- Nano-targeting is not a persuasive weapon: it is a dissuasion and polarization weapon. New paper out osf.io/preprints/so... with the brilliant Thomas Robinson, @simonhix.bsky.social and @fresejoris.bsky.social – the first to quantify the perverse incentives/inherent democratic dangers of this tech.

- 🇪🇺🇩🇪 Published Today in @bjpols.bsky.social 🇮🇹🇫🇷 How a voting advice application affected voting behavior in three large-scale field experiments: shorturl.at/2ekBj TLDR of our study (with @simonhix.bsky.social & @rlachat.bsky.social) below 👇 1/14
- Voting advice applications (VAAs) are now common tools ahead of elections in many democracies, in particular in multi-party settings. For example, in Germany, about a third of the electorate (>20 Mio. Voters) consult the Wahl-o-Mat VAA ahead of federal elections. 2/14
- How do these tools affect voting behavior? Their intended and declared purpose is to help voters make better informed vote choices, i.e., to help them vote for their ideologically most aligned party. But do they have further downstream effects (positive or negative) beyond this purpose? 3/14
