I just heard that our funding application was succesful, which means there will be a 2nd #Cars&Crime symposium on the 30/31 of July in Leeds. This time open to everyone. Call for abstracts to be circulated around Easter.
If you are doing research in this area we want to hear from you.

Yeah, I immediately imagined the chain where this metric gets built into the Elsevier submission pipeline and either you pay and it tells you your novelty score and/or editors see it on submission and make decisions. And either way they train AI on it and sell that AI to help you write/edit papers.

I received this invitation and paid it little attention, but now thinking about it, I'm angry about the concept. The project website and related Nature piece are inattentive and dismissive of any critiques of novelty and its quantification. Much effort for a new line on the Goodhart's Law wiki page.

Most research in Criminology has serious methods issues, but I take it as an opportunity rather than a source of embarrassment when teaching methods. Helps show value of fundamentals and importance of being a critical consumer of literature.

How can the use of different modes of survey data collection introduce bias? An introduction to mode effects using directed acyclic graphs (DAGs) Abstract. Survey data are self-reported data collected directly from respondents by a questionnaire or an interview and are commonly used in epidemiology.

Users of survey data, lovers of DAGs, and general methodological enthusiasts, gather round!

I'm so excited to share this new paper, joint work with my brilliant colleagues @rjsilverwood.bsky.social, @pwgtennant.bsky.social, and Liam Wright.

Screenshot of title page including the following abstract:

To minimise confounding bias and disentangle warranted from unwarranted disparities, researchers examining sentencing discrimination have traditionally sought to control for as many legal factors as possible. However, over the past decade, a growing number of scholars have questioned this strategy, noting that many legal factors are themselves subject to judicial discretion and that controlling for them can introduce post-treatment bias. Here, we use directed acyclic graphs (DAGs) to provide a formal and comprehensive assessment of the different types of bias that may arise from different choices of controls. In addition, we propose a new modelling framework to facilitate the selection of controls and reflect the model uncertainty created by the trade-off inherent in judicially-defined legal factors and other factors with a similar dual causal role. We apply this framework to examine race disparities in US federal courts and gender disparities in the England and Wales magistrates’ court. We find substantial model uncertainty for gender disparities and for race disparities affecting Hispanic offenders, rendering estimates of the latter inconclusive. Disparities against black offenders are more consistent and β€” under specific conditions β€” could be interpreted as evidence of direct discrimination.

Thrilled to share my latest paper entitled, "Estimating Discrimination in Sentencing: Distinguishing between Good and Bad Controls"

Led by @jpinasanchez.bsky.social, the paper introduces a framework for examining discrimination in criminal justice processes.

I agree completely but one should do so charitably and in good faith. I think we're too reluctant to critique work publicly (myself included!), but the infrequent critiques that are made publicly are also too often unfair and motivated by ideology either directly or indirectly to receive praise.
