Ecologist Jeremy Fox considers transparency and trust, and their observed *negative* correlation. Are we motivating better science?

Transparency vs. trust

Over the years, this blog often has been praised by readers for making the unwritten “rules of the game” (aka “hidden curriculum”) of academia explicit and transparent. Espe…

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

cup.org/4n3DvZm

Abstract for paper: Scholars increasingly conceptualize populism by whether politicians use people-centric
and anti-elite appeals that pit a homogeneous people against a corrupt elite. These appeals
reflect “thin” ideology because they offer no programmatic content and thus politicians
must pair these appeals with more substantive positions, termed their “host” (or thick)
ideology, which often consists of nativism on the right (e.g., espousing anti-immigrant
positions) and socialism on the left (e.g., prioritizing redistribution). An emerging
literature has thus sought to estimate whether populists garner support due to their thin
ideology or their substantive host ideology. To date, no research has validated whether
populism treatments (1) truly operationalize populist thin ideology, and (2) do so without
manipulating host ideology. Results from three conjoint validation experiments fielded in
both the United States and the United Kingdom show that thin ideology treatments
successfully manipulate the underlying concepts but caution that some operationalizations
also affect perceptions of host ideology.

Shows that thin populism treatments shift perceptions of people-centrism and anti-elitism as expected

Shows that thin populism treatments can also affect perceptions of host ideology. In particular, using treatments such as "American people" affects perceptions of a candidate's position on immigration

Shows suggestive evidence that people are less likely to use populist thin ideology appeals as heuristics for inferring host ideology when partisan information is included

New:

Köhler et al. (incl. @mariogollwitzer.bsky.social) developed the "Moral Perspectives & Foundations Scale" & found that perspective-specific moral foundations do a better job at predicting political outcomes than perspectives or MFTs alone.

Combining Moral Foundations and Justice Sensitivity Perspectives to Understand Political Orientation
Lucas J. E. Köhler
, Ulf Steinberg
, Maxim Egorov
, Claudia Peus
, and Mario Gollwitzer
Abstract: Political orientation is systematically related to individuals’ endorsement of different moral domains. Yet, current findings suggest that differences between conservatives and liberals can also be explained by a sensitivity to self-oriented or other-oriented moral transgressions. We argue that conceptualizing moral foundations as perspective-specific advances our understanding of differences in moral judgments across the political spectrum. We test a new instrument measuring perspective-specific moral foundations in a nationally representative German sample (N = 2,042). Our findings indicate that (a) an Integrated Foundations × Perspective Model fits the data better than models only representing moral foundations or moral perspectives and (b) a self-oriented moral sensitivity is related to right-wing political orientation, while an other-oriented moral sensitivity is related to left-wing political orientation across all moral foundations.

If you agree with our 5 requests to our universities, please sign 🖊️ the open letter and don’t forget to confirm your email! ☺️🙏

openletter.earth/open-letter-...

• Resist the introduction of AI in our own software systems, from Microsoft to OpenAI to Apple. It is not in our interests to let our processes be corrupted and give away our data to be used to train models that are not only useless to us, but also harmful.

• Ban AI use in the classroom for student assignments, in the same way we ban essay mills and other forms of plagiarism. Students must be protected from de-skilling and allowed space and time to perform their assignments themselves.

• Cease normalising the AI hype and the lies which are prevalent in the technology industry's framing of these technologies. The technologies do not have the advertised capacities and their adoption puts students and academics at risk of violating ethical, legal, scholarly, and scientific standards of reliability, sustainability, and safety.

• Fortify our academic freedom as university staff to enforce these principles and standards in our classrooms and our research as well as on the computer systems we are obliged to use as part of our work. We as academics have the right to our own spaces.

• Sustain critical thinking on AI and promote critical engagement with technology on a firm academic footing. Scholarly discussion must be free from the conflicts of interest caused by industry funding, and reasoned resistance must always be an option.
