How common are “survey professionals” - people who take dozens of online surveys for pay - across online panels, and do they harm data quality?

Our paper, FirstView at @politicalanalysis.bsky.social, tackles this question using browsing data from three U.S. samples (Facebook, YouGov, and Lucid):

I propose a three-stage model of cohortization where dynamics of cohort learning and political sorting serve as complementary engines of aggregate political change.

I apply this to the case of the killing of George Floyd & the BLM.

it's also my job market paper!
Generational Imprinting: How Political Events Shape Cohorts

Turgut Keskintürk
August, 2025

How, and for whom, do political events translate into enduring political change? This article advances a three-stage model of cohortization, in which salient events produce age differential changes in attitudes, elite cues drive identity-congruent political sorting, and life-course timing regulates whether these attitude changes remain persistent over time. Focusing on the killing of George Floyd and the Black Lives Matter protests in the summer of 2020 as a quasi-natural experiment, I test this model by analyzing attitudes toward U.S. law enforcement among non-Hispanic White Americans using five surveys that collectively span from 2016 to 2024. The findings consistently show that Democrats and Independents became strongly unfavorable toward law enforcement—much more so among younger than older individuals. Moreover, the changes persisted for younger individuals, while fading among older individuals, leading to cohort-led polarization. This article integrates two classic—though largely partial—theories of political learning, offering a model for understanding how salient events can realign generational divides.

That is, another equilibrium media market could potentially better meet public demand and be profitable, but attaining that equilibrium is difficult because single firms cannot reshape industry-level perceptions by themselves, leaving everyone locked in the same incentive structure.
atrexler.com
There is some evidence that demand is there (e.g. @emilythorson.bsky.social's experiments on policy-current info, mine on public interest news osf.io/preprints/os...) but to prevailing practice & beliefs of what news *is* create an industry-level equilibrium problem that one firm cannot overcome.

Voting access reforms in 2020 aimed to protect democracy during a pandemic, but how did they shape political efficacy and trust? This PSJ article explores the answer.

Thanks. Weighing the hassle of hand-entry for ~150 attendance records vs. the risks of group-chattable attendance survey URLs, so this is helpful.

Thanks for sharing, Jon! Have you used the physical copy attendance method previously? Debating something like this or a QR-code survey link somewhere in the slide deck each lecture.

tl;dr: taking the "marketplace of ideas" metaphor seriously requires taking the nuances of actually-existing markets seriously, which means thinking about tradeoffs between transaction costs and conformity costs. applied to misinfo and ideological belief systems.
title: Informal (De-)Regulation in the Marketplace of Ideas

abstract: Democratic societies face tradeoffs regarding the production, acquisition, and exchange of information and ideas. On the one hand, they benefit from institutions that reduce the transaction costs citizens must pay to acquire reliable information they can use to pursue their goals; on the other hand, those institutions impose conformity costs on citizens’ belief systems. This has traditionally placed civil institutions such as the media, the scientific community, and political parties in the role of informal regulators, which set norms regarding the (combinations of) beliefs citizens should or should not express in lieu of the government setting rules regarding the beliefs citizens can or cannot express. I argue that the interaction of heightened political sectarianism with changes in the structure of the public sphere have weakened these institutions and altered the informal regulations that govern the proverbial “marketplace of ideas.” This framework illuminates recent phenomena of scholarly concern – namely, the health of the political information environment and the evolution of contemporary political ideologies.

Here's a treat for state politics and policy researchers: Ethan Dee and I published a dataset in Nature: Scientific Data with the universe of state legislative bills since ~2009 coded by 28 policy areas. We used a machine learning model built off open source components.

In my view, the window to *forestall* autocratization of the US political system is basically closed. We're now in the consolidation phase of a new authoritarian constitutional settlement. The question is how far it'll get (will it achieve its apparent goal of fascism?) & at what pace.

Here's why:

Academics/adults with backpacks:

I am in the market for a new backpack. Do you have a (work) backpack that you love?

I have a North Face 'Hotshot' backpack that has served me faithfully for 10+ years but is finally wearing out, so I need to replace & want to consider options.

Some parameters:
