🚨 New draft 🚨

We built an LLM-enabled system to measure greenwashing scores in 1 million worldwide Facebook ads.

We found vast networks of Facebook pages sharing pro-fossil fuel messages & show that ads are targeted at left-leaning areas with fossil fuel investments.

Time for another episode of “bad data viz”

This one truly has me here thinking “Am I a Dolt?” What is this even saying??? Doesn’t WSJ have amazing talented staff skilled in data visualization? Like.. what is this?

It's easy to produce spurious findings:
A meaningless score based on irrelevant evaluations (“My relationship has very good Saturn”) was moderately related to common relationship measures (satisfaction, commitment) & predicted those measures 3 weeks later

This episode reminded me of 2 things:

1. We know how & why the bootstrap works, but the fact that it does is just very cool.
2. Bayes. All that strapping (& which bias adjustment to choose) just goes away as unnecessary.

We released a pretty cool dataset/preprint today looking at video game play, cognition, time-use and a ton of self-reported psych measures at osf.io/preprints/ps... with @nballou.bsky.social @matti.vuorre.com @thomashakman.bsky.social @rpsychologist.com and @shuhbillskee.bsky.social RRs coming soon
Survey administration schedule across the 12-week study period. Participants completed biweekly surveys (orange) every two weeks, with US participants additionally completing daily surveys (blue) for the first 30 days. Cognitive tests (green) were administered during biweekly surveys at weeks 1, 5, and 9. Gray circles indicate days with no scheduled surveys. Retention percentages show the proportion of baseline participants (N=1978) who were still active at each measurement week (defined as having completed either a daily or biweekly survey at any time after that week) Diurnal play across Xbox, Nintendo, Steam. Sample of daily gaming patterns and mental wellbeing for three representative participants. Stacked bars represent total daily playtime across platforms. Orange line shows biweekly mental wellbeing scores (short WEMWBS) measured at six study waves. Participants were selected from those closest to the 25th, 50th, and 75th percentiles of total playtime, prioritizing those with the most varied multi-platform gaming behavior. Participant IDs: p9009984081 (25th percentile), p8809196928 (50th percentile), p7162729307 (75th percentile)

Everyone involved in scientific publishing should take a look at these papers.

We wrote the Strain on scientific publishing to highlight the problems of time & trust. With a fantastic group of co-authors, we present The Drain of Scientific Publishing:

a 🧵 1/n

Drain: arxiv.org/abs/2511.04820
Strain: direct.mit.edu/qss/article/...
Oligopoly: direct.mit.edu/qss/article/...
A table showing profit margins of major publishers. A snippet of text related to this table is below. 1. The four-fold drain 1.1 Money Currently, academic publishing is dominated by profit-oriented, multinational companies for whom scientific knowledge is a commodity to be sold back to the academic community who created it. The dominant four are Elsevier, Springer Nature, Wiley and Taylor & Francis, which collectively generated over US$7.1 billion in revenue from journal publishing in 2024 alone, and over US$12 billion in profits between 2019 and 2024 (Table 1A). Their profit margins have always been over 30% in the last five years, and for the largest publisher (Elsevier) always over 37%. Against many comparators, across many sectors, scientific publishing is one of the most consistently profitable industries (Table S1). These financial arrangements make a substantial difference to science budgets. In 2024, 46% of Elsevier revenues and 53% of Taylor & Francis revenues were generated in North America, meaning that North American researchers were charged over US$2.27 billion by just two for-profit publishers. The Canadian research councils and the US National Science Foundation were allocated US$9.3 billion in that year. A figure detailing the drain on researcher time. 1. The four-fold drain 1.2 Time The number of papers published each year is growing faster than the scientific workforce, with the number of papers per researcher almost doubling between 1996 and 2022 (Figure 1A). This reflects the fact that publishers’ commercial desire to publish (sell) more material has aligned well with the competitive prestige culture in which publications help secure jobs, grants, promotions, and awards. To the extent that this growth is driven by a pressure for profit, rather than scholarly imperatives, it distorts the way researchers spend their time. The publishing system depends on unpaid reviewer labour, estimated to be over 130 million unpaid hours annually in 2020 alone (9). Researchers have complained about the demands of peer-review for decades, but the scale of the problem is now worse, with editors reporting widespread difficulties recruiting reviewers. The growth in publications involves not only the authors’ time, but that of academic editors and reviewers who are dealing with so many review demands. Even more seriously, the imperative to produce ever more articles reshapes the nature of scientific inquiry. Evidence across multiple fields shows that more papers result in ‘ossification’, not new ideas (10). It may seem paradoxical that more papers can slow progress until one considers how it affects researchers’ time. While rewards remain tied to volume, prestige, and impact of publications, researchers will be nudged away from riskier, local, interdisciplinary, and long-term work. The result is a treadmill of constant activity with limited progress whereas core scholarly practices – such as reading, reflecting and engaging with others’ contributions – is de-prioritized. What looks like productivity often masks intellectual exhaustion built on a demoralizing, narrowing scientific vision. A table of profit margins across industries. The section of text related to this table is below: 1. The four-fold drain 1.1 Money Currently, academic publishing is dominated by profit-oriented, multinational companies for whom scientific knowledge is a commodity to be sold back to the academic community who created it. The dominant four are Elsevier, Springer Nature, Wiley and Taylor & Francis, which collectively generated over US$7.1 billion in revenue from journal publishing in 2024 alone, and over US$12 billion in profits between 2019 and 2024 (Table 1A).

The Canadian research councils and the US National Science Foundation were allocated US$9.3 billion in that year. The costs of inaction are plain: wasted public funds, lost researcher time, compromised scientific integrity and eroded public trust. Today, the system rewards commercial publishers first, and science second. Without bold action from the funders we risk continuing to pour resources into a system that prioritizes profit over the advancement of scientific knowledge.

Abstract Science relies on integrity and trustworthiness. But scientists under career pressure are lured to purchase fake publications from ‘paper mills’ that use AI-generated data, text and image fabrication. The number of low-quality or fraudulent publications is rising to hundreds of thousands per year, which—if unchecked—will damage the scientific and economic progress of our societies. The result is editor and reviewer fatigue, irreproducible experiments, misguided experiments, disinformation and escalating costs that devour funding from taxpayers intended for research. It is high time to reevaluate current publishing models and outline a global plan to stop this unhealthy development. A conference was therefore organized by the Royal Swedish Academy of Sciences to draft an action plan with specific recommendations, as follows. (i) Academia should resume control of publishing using non-profit publishing models (e.g. diamond open-access). (ii) Adjust incentive systems to merit quality, not quantity, in a reputation economy where the gaming of publication numbers and citation metrics distorts the perception of academic excellence. (iii) Implement mechanisms to prevent and detect fake publications and fraud which are independent of publishers. (iv) Draft and implement legislations, regulations and policies to increase publishing quality and integrity. This is a call to action for universities, academies, science organizations and funders to unite and join this effort.

Construct validity is a cornerstone of psychological science.

But too often, construct validation practices fall short, leaving uncertainty about what our measures really capture.

Why is that?
