We end with guidance on how Psych & AI can benefit Cognitive Science if these traps are avoided. This alternative approach disavows attempts to automate science—using machine learning or otherwise—and instead centers scientists’ own cognition. Download here: 📝 journals.sagepub.com/doi/epub/10....

Computational concepts remain valuable for carefully crafting theories in cognitive science (Guest & Martin, 2021; van Rooij & Baggio, 2021), but they can only flourish if we 
(a) do not confuse AI systems for minds or theories, 
(b) do not confuse machine learning for the scientific method, and 
(c) understand that our computational models can track only the scope and limits of our understanding.

Combining Psychology With Artificial Intelligence: What Could Possibly Go Wrong?

Abstract
The current AI hype cycle combined with psychology’s various crises make for a perfect storm. Psychology, on the one hand, has a history of weak theoretical foundations, a neglect for computational and formal skills, and a hyperempiricist privileging of experimental tasks and testing for effects. Artificial intelligence, on the other hand, has a history of conflating artifacts for theories of cognition, or even minds themselves, and its engineering offspring likes to move fast and break things. Many of our contemporaries now want to combine the worst of these two worlds. What could possibly go wrong? Quite a lot. Does this mean that psychology and artificial intelligence can best part ways? Not at all. There are very fruitful ways in which the two disciplines can interact and theoretically contribute to cognitive science, for instance, by studying the scope and limits of computational models of human cognition. But to reap the fruits, one needs to understand how to steer clear of potential traps.

Keywords
theoretical psychology, artificial intelligence, cognitive science, computationalism, epistemology

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.
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.

Figure 1
Illustration of why AI systems cannot realistically scale to human cognition within the foreseeable future: (b) Human cognitive capacities (such as reasoning, communication, problem solving, learning, concept formation, planning etc.) can handle unbounded situations across many domains, ranging from simple to complex. (a) Engineers create AI systems using machine learning from human data. (d) In an attempt to approximate human cognition a lot of data is consumed. (c) Making AI systems that approximate human cognition is intractable (van Rooij, Guest, et al., 2024), i.e., the required resources (e.g. time, data) grows prohibitively fast as input domains get more complex, leading to diminishing returns. (a) Any existing AI system is
created in limited time (hours, months or years, not millennia or eons). Therefore, existing AI systems cannot realistically have the domain-general cognitive capacities that humans have. [Made with elements from freepik.com.]

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.

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

Some examples of decolonial automata/computations, apropos of giving a mini talk on this tomorrow: Towards Critical Artificial Intelligence Literacies doi.org/10.5281/zeno... 🐯 Tipu's tiger is amazing; sadly stolen & now in the V&A, created in India & depicting a tiger mauling an English man. 1/n
On the flip side, we can include positive examples in our teaching on the history of AI: Tipu’s
tiger from late 18th century India, featuring the eponymous robotic cat mauling a European man
(Karp et al. 2013); the Antikythera Mechanism from ancient Greece, which was a clockwork astro-
logical calender; and the Mayans’ calendrical system that was highly precise and directly translat-
able to a system of gears. We can also explain the origin of ‘algorithm’ and ‘algebra’, conceptually
developed during the Islamic Golden Age. These serve not only to properly contextualise the his-
tory of AI (Mayor 2018), but to reimagine with students what could be done differently.
Regardless of AI, science has always been intertwined with domination, extraction, binary
thinking, and the imposition of hierarchies (Tacheva et al. 2023). For example, the Cartesian dualist
idea that the mind can be separated from the body is at the core of AI hype. Corporate discourses
around AI feature preposterous claims, such that ‘ChatGPT has PhD level cognition capacities’,
and they will be able to surpass human intelligence in the near future (Welt 2025), implying that
technologies are human-like. However, far from LLMs having cognitive capacities, companies ob-
fuscate the labour that is extracted from data workers (Miceli et al. 2020). In the classroom, we
should question the mind and body binary and render visible its eugenical and colonial legacies.
While we refute corporate claims, we also take them seriously as dehumanising workers, women,https://en.wikipedia.org/wiki/Tipu%27s_Tiger Tipu's Tiger, Tippu's Tiger or Tipoo’s Tiger is an 18th-century automaton created for Tipu Sultan, the ruler of the Kingdom of Mysore (present day Karnataka) in India. The carved and painted wood casing represents a tiger mauling a near life-size European man. Mechanisms inside the tiger and the man's body make one hand of the man move, emit a wailing sound from his mouth and grunts from the tiger. In addition a flap on the side of the tiger folds down to reveal the keyboard of a small pipe organ with 18 notes.[1]

The Maya Calendar System
Using their knowledge of astronomy and mathematics, the Maya developed one of the most accurate cal-
endar systems in human history. The Maya calendar system has its roots in older, Mesoamerican1 indig-
enous civilizations, particularly the
Olmec. The Maya calendar is complex
and serves both practical and ceremoni-
al purposes. The Maya calendar system
includes several calendars that mea-
sure time periods of varying lengths.
These calendars are based on solar,
lunar, planetary, and human cycles.
There are three most commonly known
cyclical calendars used by the Maya.
These include the Haab which is a 365-
day solar calendar, the Tzolk’in which
is a 260-day sacred calendar, and the
Calendar Round of 52 years. In
addition, the Maya developed the Long
Count calendar to date mythical and
historical events chronologically.
1 Definitions for words in red-colored font can be found in the Glossary page in the Resources section of the “Living
Maya Time” website.
A contemporary representation of the Tzolk’in (inner green circle)
and Haab (outer brown circle) calendars.
The Haab
The Maya solar calendar, called Haab, is a count of 365 days and thus approximates the solar year. The word
“haab” means “year” in the Yucatec Mayan language. The Haab is composed of 18 months made of 20 days
each, plus one month made of 5 days. A month made of 20 days is called a uinal. Each uinal has its own
name. These 18 months together equal 360 days. The last month made of 5 days is called Wayeb. The 19
months together total 365 days.
18 x 20 + 5 = 3652

It's GENUINELY like this: You cannot "solve" intractability with heuristics. Trust me. I devoted 20 years to this, and really, if you squeeze out intractability in one spot it'll pop up in another. It may look different on the surface, but in essence you're still facing the same epistemic problem.

Box 2. Proof intuition
NP-hard models are considered to be intractable, because there do not exist any tractable (formally, polynomial-time) algorithms for computing them (unless P = NP, see footnote 1). How can one prove that a computational model is NP-hard (and thus intractable)? A model is NP-hard if it is at least as hard as another NP-hard model, that is, one can use the former to compute the latter with minimal (only polynomial) overhead. We can prove such a relationship using polynomial-time reduction, a technique from computational complexity (Garey & Johnson, 1979). In the supplementary materials, we use this technique to prove that Adaptive Toolbox is NP-hard. Specifically, we reduce from the known NP-hard graph problem Dominating Set (which takes as input any graph and asks as output a so-called dominating set, that is, a subset of vertices with the property that for each vertex v in the graph, either v or one of its neighbors is in the subset). This is done as follows:
Provide a tractable (polynomial-time) algorithm that transforms any input iDS for Dominating Set into input iAT for Toolbox Adaptation (proof step 1 in Supplementary Materials).
Show that after the transformed input is processed as specified by Toolbox Adaptation, the resulting output oAT can be transformed back into a solution oDS for Dominating Set (proof steps 2 and 3).
Both transformations only take polynomial time to compute. This means we can use Toolbox Adaptation to solve Dominating Set with minimal (only polynomial) overhead.
Toolbox Adaptation is NP-hard, because it is at least as hard as the NP-hard problem Dominating Set.
This is, in a nutshell, the strategy we used to prove that Toolbox Adaptation is NP-hard. Fig. 2 illustrates this strategy.

"Mensen onderschatten vaak wat de menselijke cognitie allemaal kan, en overschatten wat AI systemen kunnen. Velen geloven dat hedendaagse AI systemen zich binnenkort tot echte AGI zullen ontpoppen (of zelfs al AGI zijn). Mijn collega’s en ik hebben onlangs wiskundig bewezen dat dit onzin is."

Gezien de opnieuw oplaaiend angst voor "artificial general intelligence" (AGI), aangewakkerd door de AI industrie en de media, gooi ik even deze post in de herhaling: www.beste-id.nl/salon/denken...
