More and more I feel like I need to end these conversations by saying "it sounds like you've made up your mind to rationalize your choices despite knowing what the harms are, and that's very unfortunate because I thought you had better judgement than that"

Sometimes I feel the discussion on AI use devolves into: A: I'm allowed to use copy-paste! You use it all the time, right? B: I don't use it to plagiarise, reproduce sexism, or pollute the environment. A: OK, but it's useful & fast for me! And um, that's really degraded thinking on A's part.

That's why regulation is so good. If you do it okayly enough it works. AI and other regulation can work too if we preserve. > the passing of the Children Act 1989 caused most British schools to ban the practice and it is now obsolete in Britain.

See, e.g., Section 4 in our position paper for an overview of how the principles can be applied to 'AI': 📝 @olivia.science , @marentierra.bsky.social et al. (2026). Against the Uncritical Adoption of 'AI' Technologies in Academia. Digital Culture & Education, 16(2), 85–118. doi.org/10.5281/zeno...
Honesty implies that we do not secretly use AI technologies without disclosure, and that one does not make unfounded claims about the presumed capabilities of AI technologies (this also follows
from Responsibility; see example from MIT Economics 2025, where perhaps too little too late was
done).

Scrupulousness demands, among other things, that scientists only use AI products whose functional-
ity is well-specified and validated for its specific scientific usage (cf. Kwisthout 2024; Kwisthout and
Renooij 2025). This includes terminological precision about what formalisms, models, and/or tech-
nologies are used (recall Figure 1) and rigorous argumentation to motivate why these technologies
are appropriate for the scientific purposes at hand.
Transparency requires that the AI technologies are open source and computationally reproducible.
Here we must recall the technology industry’s obfuscatory tactics: “the name of the current
producer of ChatGPT. ‘OpenAI’ sounds like it is engaged in open science, but as we have now
seen, ‘open’ never really means what you think it does.” (Mirowski 2023, p. 738; see also Dingemanse
2025; Hao 2025; Jackson 2024; Liesenfeld and Dingemanse 2024; Liesenfeld, Lopez, et al. 2023;
Maffulli 2023; Maris 2025; Nolan 2025; Solaiman 2023; Thorne 2009; Widder et al. 2024)
Independence means that scientists ensure that their research is unbiased by AI companies’ agendas,
and that any potential conflicts of interest are declared in publications and other public communi-
cations (this also follows from Honesty and Transparency; cf. Mohamed Abdalla and Moustafa
Abdalla 2021; Atkin 2025; Forbes and Guest 2025; Knoester et al. 2025).
Responsibility precludes scientists from using AI products whose use is irresponsible, e.g. harmful to
people, animals, and the environment, or otherwise in violation of legal guidelines (e.g. copyright,
data privacy, labour laws, Butterick 2025; Cole 2025; Rijo 2025; Tafani 2024a). Minimizing harm is
vital for both engin…

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.

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

AI boomers vs. doomers: A false dichotomy

The AI cult’s adherents are no more monolithic in their beliefs than followers of any religion are: there are many subgroups who vigorously debate and contest each other’s beliefs. Yet these subgroups share enough common beliefs that we can usefully group them into a single category, even as it is helpful to understand the main theological disputes between the different currents. Indeed, Gebru and Torres describe the disparate strands behind each letter of “TESCREAL” as a “bundle” of “interconnected and overlapping ideologies” with roots in 20th-century eugenics. Émile Torres’s newsletter helpfully summarizes the bundle’s commonalities and differences:

We present a typology of traps to avoid: 1. Believing that AI systems are minds 2. Believing that AI systems are theories 3. Believing that cognitive science can be automated. Learn to recognise and avoid these traps. Failure to avoid leads to numerous problems. 3/🧵
Table 1: Typology of traps, what goes wrong if not avoided, and how the traps can be avoided. Note that all traps in a sense constitute category errors (Ryle & Tanney, 2009) and the success-to-truth inference (Guest & Martin, 2023) is an important driver in most, if not all, of the traps.

ultimately: what is a scientific theory? olivia.science/theory/#what

what's a
theory?

Each person might have their own idea of what a theory is, but for this context and to help understand where I am coming from, here's a definition from Guest and Martin (2021, p. 794):

    A theory is a scientific proposition — described by a collection of natural‐language sentences, mathematics, logic, and figures — that introduces causal relations with the aim of describing, explaining, and/or predicting a set of phenomena.

You will have to look at Guest and Martin (2021) to fully grasp how I separate theory from other scientific concepts, especially if you cannot yet disentangle it from hypothesis, a different beast altogether.
