Earlier this year, Alicja Kwade had a magnificent solo-exhibition in museum M Leuven. In the catalogue, I compare her sculptures with scientific models: "In the sway of a simple model; A philosophical reflection on Alicja Kwade’s pendulum". Pdf: www.sylviawenmackers.be/documents/We... #Art #PhilSci
Exhibition catalogue of Alicja Kwade, called Dusty Die. The cover shows a white door.Double-page photo of ParaPosition, in which a heavy rock balances above a chair. The wall in the background shows a photo of gray clouds; a real window shows the inner garden.Fragment of my chapter. Scientists usually think and communicate about fictional systems by means of equations and specific names, such as the ‘simple pendulum’, ‘frictionless plane’ or ‘ideal gas’. In doing so, they simulate these abstract model systems mentally. At best, they leave behind cryptic squiggles on a blackboard. In Kwade’s work we encounter similar conceptual abstractions, but she renders them as physical, material objects. She presents us with massive rocks that appear to defy gravity in works like Superheavy Skies and ParaPosition, which make tangible the kind of configurations that scientists only imagine.
It’s like Kwade read Godfrey-Smith’s concept of scientific models as ‘imagined concrete systems’ that ‘would be concrete if real’ (or ‘fictional concreta’) and called his bluff. As if Kwade decided: let’s make them real, then!

A bit of an inspection paradox: 🤓 I was part of 5 thesis defenses today and didn't see any women there. Yet, for the other jury members, their colleagues' gender distribution was 50/50, and for the students, jury's gender imbalance was never <1/3. Anyway, my working day didn't pass the Bechdel test.

Gene name errors are widespread in the scientific literature - Genome Biology
The spreadsheet software Microsoft Excel, when used with default settings, is known to convert gene names to dates and floating-point numbers. A programmatic scan of leading genomics journals reveals that approximately one-fifth of papers with supplementary Excel gene lists contain erroneous gene name conversions.

This is the funniest thing I've read all week. In 2024, a retraction for serious issues was framed by its authors as a "Retract, revise and resubmit" over a single misleading sentence. They're sticking to it, somehow maintaining that minor error story amidst an apparent two year revision process.

To explain this a bit more, a core tension in this exchange was that only the critiqued authors had access to metadata for Web of Science, such as the number of cited references. Every fast step in this story ran through open code and data. And every slow step ran through closed ones. 2/7

There are multiple reasons for the delay. A Matters Arising is peer reviewed. Park et al. kept changing their defence, and every iteration took many months. The original authors had no incentive to reply swiftly and even outright refused to share data ‘available upon request’. 1/7

Instead of a decline in the disruptiveness of scientific and technological knowledge, the data mainly show an increasing metadata quality over time: relatively fewer papers with zero references due to database errors. 7/8
The decline in disruption (including zero reference papers, left panel) mirrors the relative decrease of zero reference papers which were wrongly counted as being maximally disruptive (right panel).

The Monte Carlo simulations randomly rewired citations while preserving each paper's number of references. Zero-reference papers are thus preserved, and the rewired networks inherit the peak at CD=+1. Their decline mirrors the observed decline in disruption. 6/8
Randomly re-arranging the citations between papers preserves the number of references made (top left). This means the zero reference papers are mapped one-to-one in the observed and randomly rewired network, as visible by the peak at one in both distributions (bottom left). The randomly rewired CD index over time almost perfectly mirrors the observed trend, and the gap is closing (right).

Why didn’t the robustness checks catch this? The linear regression did not control for the discontinuity of the CD index at zero references. Simply adding a dummy for zero references improves the adjusted R^2 from 0.15 to 0.95, and the adjusted CD index becomes essentially flat. 5/8
The Park et al. regression adjustment did not control for the disconinuity of the CD index appearing at zero references. Adding a dummy to control for it substantially boosts the adjusted R^2 and the regression adjusted curves become nearly flat.

Why so many papers with a CD index of exactly 1? In the open-source SciSciNet database, 97% of them make zero references. Of 100 randomly sampled source documents, 93 do contain references. They are dataset artefacts. 4/8
The CD index has a discontinuity at zero references, as every paper gets automatically assigned a maximum value of +1. This correspondence is almost one-to-one: the majority of papers with a CD index of exactly equal to +1 have zero references, an observation that is stable over time.

When removing the hidden outliers with CD = +1, the reported decline in disruption largely disappears across all databases used in the Nature study. For Web of Science, it reduces by 93 %. 3/8
Removing the hidden outliers negates the decline in disruption across all databases used in the original study. Compared the the original scale (on the left), all curves depicting scientific papers become flat (on the right).

Due to a (then unreported) bug in the seaborn plotting software, the published histograms silently dropped the largest data points. A peak of papers with the maximum disruption score of CD = +1 was hidden from view, while these papers were kept in the analysis. 2/8
Due to a bug in the seaborn plotting software, the largest data points (+1 in this case) were omitted in the CD index distributions shown in the original study (on the left). Correct plot settings (using bins instead of binwidth) reveal a huge peak at papers with a CD index of exactly equal to one (on the right).

The study is based on the CD index, a citation-based measure of how much the successors of a work still rely on its predecessors, running from -1 (consolidating) to +1 (disruptive). Key detail: a paper with zero references automatically gets CD = +1 as soon as it is cited once.
The CD index aims to rely the successors of a given work to its predecessors by counting how many citing papers still refer to the references of a given work. In case zero references and at least one citation, the measure defaults to +1.
