Why do we cooperate with the police & criminal courts?👩‍⚖️

In a new 30-country study, Jon Jackson, Jouni Kuha, @benbradford.bsky.social & Mike Hough find that fair & respectful authority usually beats crime control & fear – but procedural justice power varies by country

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.

🔍 New Research Alert 🔍

Do protection orders really reduce reoffending in intimate partner violence cases?

I just co-authored a new open-access study that tackles this question in the Journal of Developmental and Life-Course Criminology.

link.springer.com/article/10.1...
'As Time Goes By': The Effectiveness of Protection Orders in Reducing Intimate Partner Violence Recidivism - Journal of Developmental and Life-Course Criminology
This study investigates the effectiveness of protection orders in reducing intimate partner violence (IPV) recidivism. Protection orders are legal measures imposing restrictions on aggressors to prevent them from approaching or contacting their victims. These legal measures have seen rapid international expansion in recent years. However, understanding the extent to which they work remains an ongoing challenge. To contribute to this debate, we employ Cox standard proportional hazards models and Prentice–Williams–Peterson gap-time models for recurrent events using a new dataset, which includes comprehensive registry data from an entire cohort of more than 6000 aggressors sentenced for at least one IPV crime over a five-year period, followed for at least four years. Our findings unveil an initial, average adverse effect of protection orders on recidivism. This effect becomes non-significant after excluding breaches of the orders and after controlling for judges’ tendency to impose these measures on high-risk offenders. Moreover, we observe that the effects of protection orders vary over time: While there is an adverse immediate impact of holding an order, a positive temporal cumulative effect counteracts it after a few months.
