Nice + accessible overview of my @jepsjournal.bsky.social paper on validating populism treatments, showing that some “thin” populism treatments also affect perceptions of host ideology. Also makes broader point about validating conjoint treatments #Openaccess paper: www.cambridge.org/core/journal...

Our job as mentors is to identify our students' strengths and areas that can be developed. My PhD student (psych), Sydney Tran, has deep substantive interests, but also enviable methodological range. Her first, first-author publication is tagged below.

Call for Nominations!
The ISPP is seeking nominations for several leadership roles, including President-Elect, Vice President for Communications and Publications, and five members of the Governing Council (serving July 2026–July 2029).

Key items for #polisky:

(1) due November 12, 2025

(2) ONLY undergrad seniors, bachelor's not in grad programs, OR 1st-year grad students eligible (whether in a master's or PhD program)

(3) fund all projects but emphasis on "high-priority research areas in alignment with Admin priorities" like AI

Thanks for sharing, Drew. This is going straight into my lecture slides.

This rethinking of MI from @dingdingpeng.the100.ci and @boryslaw.bsky.social is going straight to the syllabus.

I've also thought MI useful as a way to test substantive hypothesis, so this was clarifying more generally.

Thanks, Drew! I was hoping the paper could be useful for thinking through information equivalence/masking concerns in conjoint experiments (and other designs) more broadly.

Thanks Efrén!

Also came here to say there's a non-zero chance of this.

I'm not at APSA, but I will still be buying too many books because a bunch of great presses are running conference sales. I'll try to collect them all below. Feel free to add more. And self-promote if your book is on sale!!

Thanks Markus. Hope you find it helpful - I cite your paper as a good example of treatment/stimulus sampling.

Now Out on First View: "Can (Thin) Populism be Manipulated without Manipulating Host Ideology? Evidence from a Conjoint Validation Approach"
www.cambridge.org/core/journal...

Thanks!

Broader point: Conjoint experiments usually do not include manipulation checks. But due to information equivalency/masking concerns it is still important to validate that (1) treatments manipulate construct of interest, without (2) also manipulating other constructs.

Implications for study of populism: it is difficult - even in conjoint experiments - to disentangle effects of (thin) populism and host ideology

Additional finding: respondents are less likely to use thin ideology appeals to make inferences about host ideology when partisan labels are provided

New preregistered report @jepsjournal.bsky.social

"Thin" populism treatments manipulate perceptions of people-centrism + anti-elitism

But: some treatments (e.g., "American people") affect perceptions of host ideology, complicating causal analyses of impact of populist rhetoric

Ask re #APSA2025: The political psychology division has a number of panels that need additional discussants. If you're attending APSA and are willing to serve in such roles please get in touch with @carlynwayne.bsky.social and I. See screenshot for panels. Thanks in advance!

There's a new issue of the section newsletter out! This one's on sample considerations in experiments: professional survey-takers, LLM usage, rural contexts, and more!
