Post Daniel Laurison ‪@daniellaurison.bsky.social‬ This is a great piece! One of the recommendations is to focus on turnout over moderation, which I 100% agree with. There were steep declines in turnout among low-income voters in 2024; Grumbach & Bonica point to the increased racial gap in turnout to ~11%, income gaps were closer to 30 points. Chart with Turnout on the Y axis & election year (2016, 2020, and 2024) on the X axis. 6 lines, 3 for White, Black, and Hispanic in households making over $100k/year, 3 for the same groups in households making under $30k/year. Overall you can see turnout increasing among higher-income people in all three racial groups, and declining (White and Black) or staying flat (Hispanic) among low-income people; the turnout gap by income is much larger in 2024 than in 2020 or 2016. from 2016 -> 2024: - White $100k turnout goes from 65% to 78% while white under $30k turnout goes from 55% to 49% - Black over $100k turnout goes from 51% to 64% while Black under $30k turnout goes from 48% to 33% - Hispanic over $100k turnout goes from 52% to 67% while Hispanic under $30k turnout stays flat at about 36% (higher in 2020 at 42%).

chart showing family income of voters & non-voters in 2024; people in families earning under $50k/year were over half of nonvoters; more than half of voters had incomes over $70k.

I keep posting these images because they get at a really deep problem - the class divide in political participation.
Those who want our democracy to truly represent all its citizens need to create and sustain real connections with people and communities who do not currently feel represented.

My colleague Kevin Munger asked me and a bunch of editors to sit and think through AI and peer review. Our take:

Call for Proposals: Data Collection for Replication+Novel Political Science Survey Experiments Alexander Coppock and Mary McGrath January 27, 2026 We invite proposals for a survey experiment replication+novel design competition. Se- lected replication+novel design survey experiments will be conducted on large samples of American respondents, quota sampled to match U.S. Census margins and filtered for quality and attention by the survey sample provider Rep Data (repdata.com). Each proposal consists of two parts: (1) a replication study of an existing, previously published survey experiment, and (2) a novel experimental design on a topic of the authors’ choosing. The replication studies and reanalyses of the existing studies will be combined into a meta-paper to be co-authored by all authors of accepted proposals along with the princi- pal investigators (Coppock and McGrath). As a condition for acceptance, authors commit to sharing the data and producing a write-up of the findings from their novel design for submission to a scholarly journal, and public posting of a working paper pre-publication.

🎺 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

This 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

Overall, I was impressed with how effective many of these quite simple and brief interventions were at inducing behavioral change. Based on partisan heterogeneity, they won’t help recruit skeptics into the broader climate-mitigation coalition but rather mobilize those who are already in it. 10/11

Heterogeneity across many other dimensions can be further explored in this interactive web tool: climate-advocacy-megastudy-0f5581d24099.herokuapp.com 9/11

However, there is strong heterogeneity by partisanship/ideology in how receptive people are to such behavioral interventions. Democrats (who are already greener on average) responded positively to many interventions, while Republicans were not receptive whatsoever. 8/11

Furthermore, these positive effects also translate into directly verifiable behaviors for many of these interventions, such as donation behavior which was measured directly, beyond just self-reports. 7/11

… political advocacy (sign petitions, write letters to representatives), and personal lifestyle changes (eat less meat, fly less). Across most outcomes, many of the interventions significantly increased pro-climate behaviors compared to the control condition. 6/11

Each respondent was randomly exposed to one intervention. Afterwards, self-reported behavioral measures were surveyed, related to the willingness to participate in public advocacy (eg share newsletters or videos), financial advocacy (switch to a green bank or make donations), 5/11

The most promising interventions were experimentally tested on a quota-matched sample of 31000 US respondents and compared to a control condition with no intervention and an established intervention known to induce attitudinal change. 4/11

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

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

RegCheck RegCheck is an AI tool to compare preregistrations with papers instantly.

Comparing registrations to published papers is essential to research integrity - and almost no one does it routinely because it's slow, messy, and time-demanding.

RegCheck was built to help make this process easier.

Today, we launch RegCheck V2.

As the Spring semester kicks off, just a reminder that I have collected over 100 datasets that could be of use to undergrads/grads doing their first quant research projects!

Over 96% of these clearly opposite item pairs are positively correlated on MTurk. In other words, many respondents give similar answers to statements that literally contradict each other.

We're excited to release version 1.0 of the Dynamic Democracy website. It includes updated data on state policy, public opinion, mass ideology, and representation. The website enables you to see how these measures are changing overtime across states and within states.
