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.
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%).

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.

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.

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.

A well-deserved recognition and an example of how simple the improvement of science can be at times: one small policy change will disincentivize fraud and plagiarism at scale in the country with the 3rd-highest number of retractions in the world (depends of course on the quality of implementation).

New paper in @ajpseditor.bsky.social. Is descriptive representation good for substantive representation? Why do voters stay loyal to corrupt and poorly governing ethnic parties? I argue that we ought to focus less on patronage and more on dignity concerns. Defiant pride can come at a price. 1/🧵
