Germany is that country where one governing party stages a protest walk against the other governing party (their coalition partner) as photo op, instrumentalizing nazi history in the process. Politics is basically 100% denial now, send help.

Indeed. Here's Selfridge in the discussion of McCarthy's common sense paper at the 1958 Mechanisation of Thought Processes Symposium (Vol 1, p. 87), where, among others, Grace Hopper was present.
snippet of text (Selfridge in reply to Bar-Hillel):
"(...) Deductive logic is inferred as much as anything else. Most women have never inferred it, but they get on perfectly well, marrying happy husbands, raising happy children, without ever using deductive logic at all."

Statistical power has been lionized in metascience. First, you care about statistical power only bec your whole scientific vision relies on the results of a hypothesis test. Get over it. Second, power can never make up for poor design, lack of theoretical understanding, or biased samples/measures.

"We still don't know how large or reliable the effect is" suggests you need more exploration bec you have not stabilized the effect yet. That is not something a replication (esp. non-exact), however large, can answer for you. You need to do more groundwork to figure out what phenomenon you study.

Like, when there was a brief 70s revival in the late 90s, I started listening to my parents' vinyl records and wearing my mum's old flares. And surely got most of the (sub-)cultural markers completely wrong, because my only references were repeats of Top of the Pops (well, the German equivalent)

Similarly sad about unauthentic retro computing. But hasn't co-opting past decades' cultural artefacts as broadly "retro" (i.e. with little regard for authenticity) been around for ages?

Dear @erc.europa.eu , we DO already have common standards & frameworks. 'AI' likes to pose itself as 'special' but we do not need to reinvent the wheel. We already have established codes of conduct for research integrity. We just need to apply them. See below + more resources in thread🧵
Protecting the Ecosystem of Human Knowledge: Five Principles
We must protect and cultivate the ecosystem of human knowledge. AI models can mimic
the appearance of scholarly work, but they are (by construction) unconcerned with truth
— the result is a torrential outpouring of unchecked but convincing-sounding “informa-
tion”. At best, such output is accidentally true, but generally citationless, divorced from
human reasoning and the web of scholarship that it steals from. At worst, it is confidently
wrong. Both outcomes are dangerous to the ecosystem.
Olivia Guest, Iris van Rooij, Marcela Suarez, et al. (2025, n.p.)
Knowledge production is supposed to be safeguarded by (inter)national codes of conduct for research
integrity (ALLEA 2023; KNAW et al. 2018). Such codes forbid, for instance, fabrication of data,
falsification of results, plagiarism, and, generally, distortion of the scientific record. Many argue that
new rules are required to regulate academic AI use, but pre-existing guidelines fit the bill (cf. Tafani

So how about this for a "pause AI" proposal: "pause credulous AI reporting". No more media about "breakthroughs" or "rogue agent swarms" or ... UNLESS and UNTIL that media demands the actual empirical evidence and/or focuses on the motivations of & harms by these companies.

Description

Computational models in psychology are typically judged by a single standard: empirical fit. Unfortunately, fit is insufficient, even misleading as a sole criterion, as the same result can arise from fundamentally different situations: theoretically faithful models, mathematically flexible ones, miscalibrated operationalizations, or implementations that compute something other than intended. Distinguishing between these is vital. Our evaluative metatheoretical account recognises that models stand in three distinct relations: a) toward the theory whose causal commitments it purports to capture, b) toward the specification and implementation it purports to compute, and c) toward the phenomenon it purports to explain. Each relation can succeed or fail independently, governed by criteria local to that stage. Importantly, relations are ordered such that theoretical content is transmitted or lost, and losses at earlier transitions are irrecoverable downstream. What a model's empirical success implicates about its theoretical commitments, therefore, depends on whether transitions are secured. Some success or failure profiles support explanatory claims; others only prediction; others establish theoretical coherence without empirical contact. Our account diagnoses what a given model shows, replacing the implicit assumption that empirical success transfers automatically to theoretical understanding with an explicit conditional rendition of what models can and cannot establish.

"We should not be content with theories and models that prioritize numerical correlation over explanation that blur their metatheoretical ties, and which render our fields closer to pseudoscience. Computational cognitive science in principle can and should do more than merely model data."

One thing we tried was to have participants type their intermittent notes into essentially a chat interface, with us (given skill in task domain & interviewing techniques) reading along in realtime (with pp's consent), enabling us to clarify ambiguities in a subsequent debriefing interview

Among other things, this involved careful practice sessions with participants (not leading on, but letting them encounter common problems themselves, develop their own reporting style), separating task work and reporting, but keeping them very close still ("event-contingent immediate retrospection")

Topologie | Konstruktion einer Kreuzfaltung:
Selbstbeobachtungen zum lebendigen Denken

Cornell Schreiber

In diesem Aufsatz berichte ich von meinen Selbstbeobachtungen zur wie folgt lautenden Aufgabe:

Falte ein A4-Blatt in deiner Vorstellung, so oft es dir gelingt, nacheinander abwechselnd horizontal und vertikal. Beachte dabei die Form, die das Blatt nach jeder Faltung annimmt. Nimm dazu kein »echtes« Blatt zur Hilfe. Die in der Aufgabenstellung besagte Kreuzfaltung dürfte den meisten aus eigener Erfahrung wohlbekannt sein, zum Beispiel als Falttechnik, einen A4-Briefbogen auf die Größe einer Postkarte zu komprimieren. Schnell hat man ein Papierblatt binnen weniger Handgriffe und nahezu automatisch über Kreuz gefaltet. Der genauen Form des Blatts, etwa den Kantenformen an seinen Seiten, muss man sich dabei nicht
widmen.

Hingegen stellt die Aufgabe, eine mehrfache Kreuzfaltung vorzustellen, eine Herausforderung für unseren kognitiven Apparat dar – und ist insofern von denkpsychologischer Relevanz. In der Vorstellung können die Konsequenzen einer Faltung nicht mühelos am echten Blatt »abgelesen« werden. Stattdessen muss man die immer komplexer werdenden Formen des Blatts im Arbeitsgedächtnis konstruieren: angefangen bei einfachen Intuitionen von Blatt und Faltung müssen die Strukturen des mehrfach-gefalteten Blatts aus den Strukturen des jeweiligen Ausgangszustands nach und nach neu »zusammengesetzt« werden.

Abstract

Successful problem solving relies on the availability of suitable mental representations of the task domain. Especially for more complex problems, there might be a wide variety of possible problem representations, and it might even be beneficial to change them during problem solving. In a first part, we argue that investigating the dynamics of understanding in terms of dynamically changing problem representations is an underexplored aspect of problem solving research, and that most classic tasks even preclude the opportunity of such dynamics to occur. Continuing this theoretical discussion, as an illustrative example of a task designed for the exploration of such representational dynamics, the second part of the paper discusses a novel, complex spatial transformation and problem solving task. In this task, one is asked to repeatedly mentally cross-fold a sheet of paper, and to predict the resulting sheet geometry without the use of external aids. Through its deliberate openness and difficulty, this task requires finding new and more efficient representations – ranging from kinaesthetic and visuospatial imagery to symbolic notions. We present an overview of the task domain and discuss various ways of representing the domain as well as potential dynamics between them.
