Can we quantify what makes some text read like AI "slop"? We tried 👇

Chantal @chantalsh.bsky.social · 14d

"AI slop" seems to be everywhere, but what exactly makes text feel like "slop"?

In our new work (w/ @tuhinchakr.bsky.social, Diego Garcia-Olano, @byron.bsky.social ) we provide a systematic attempt at measuring AI "slop" in text!

Language Models Fail to Introspect About Their Knowledge of Language

There has been recent interest in whether large language models (LLMs) can introspect about their own internal states. Such abilities would make LLMs more interpretable, and also validate the use of s...

🤖 🧠 NEW PAPER ON COGSCI & AI 🧠 🤖

Recent neural networks capture properties long thought to require symbols: compositionality, productivity, rapid learning

So what role should symbols play in theories of the mind? For our answer...read on!

Paper: arxiv.org/abs/2508.05776

1/n

The top shows the title and authors of the paper: "Whither symbols in the era of advanced neural networks?" by Tom Griffiths, Brenden Lake, Tom McCoy, Ellie Pavlick, and Taylor Webb.

At the bottom is text saying "Modern neural networks display capacities traditionally believed to require symbolic systems. This motivates a re-assessment of the role of symbols in cognitive theories."

In the middle is a graphic illustrating this text by showing three capacities: compositionality, productivity, and inductive biases. For each one, there is an illustration of a neural network displaying it. For compositionality, the illustration is DALL-E 3 creating an image of a teddy bear skateboarding in Times Square. For productivity, the illustration is novel words produced by GPT-2: "IKEA-ness", "nonneotropical", "Brazilianisms", "quackdom", "Smurfverse". For inductive biases, the illustration is a graph showing that a meta-learned neural network can learn formal languages from a small number of examples.

Yes, at least need other data (like Echos in AI), quality measure (LitBench), also what we did in QUDsim was to make sure the stories are from posts pre-LLM to prevent AI stories. Further, The way they measure style + semantic diversity doesn't align with how they define it (only capture lexical)

I agree this thread's headline claim seems premature. Let me add our recent ACL Findings paper, with Dexter Ju and @hagenblix.bsky.social, which found syntactic simplification in at least some LMs, in a novel domain regeneration setting: aclanthology.org/2025.finding...

The Echoes in AI paper showed quite the opposite with also a story continuation setup.
Additionally, we present evidence that both *syntactic* and *discourse* diversity measures show strong homogenization that lexical and cosine used in this paper do not capture.

Turns out content selection in LLMs are highly consistent with each other, but not so much with their own notion of importance or with human’s…

Jessy Li @jessyjli.bsky.social · Feb 21

Do you want to know what information LLMs prioritize in text synthesis tasks? Here's a short 🧵 about our new paper, led by Jan Trienes: an interpretable framework for salience analysis in LLMs.

First of all, information salience is a fuzzy concept. So how can we even measure it? (1/6)

Check out this new opinion piece from Sebastian and Lily! We have really powerful AI systems now, so what’s the bottleneck preventing the wider adoption of fact checking systems, in high stakes scenarios like medicine? It’s how we define the tasks 👇

Lily Chen @lilywchen.bsky.social · Jul 1

Are we fact-checking medical claims the right way? 🩺🤔

Probably not. In our study, even experts struggled to verify Reddit health claims using end-to-end systems.

We show why—and argue fact-checking should be a dialogue, with patients in the loop

arxiv.org/abs/2506.20876

🧵1/

An overview of our AI-in-the-loop expert study pipeline: given a claim from a subreddit, we extract the PIO elements and retrieve the evidence automatically. The evidence, its context, and the evidence are then presented to a medical expert to provide a judgment and a rationale for the factuality of the claim.

Jessy Li @jessyjli.bsky.social · Jun 3

We have very good frameworks for cooperative dialog… but how about the opposite? @asher-zheng.bsky.social’s new paper takes a game-theoretic view and develops new metrics to quantify non-cooperative language ♟️

Turns out LLMs don’t have the pragmatic capabilities to perceive these…

Asher Zheng @asher-zheng.bsky.social · Jun 3

Language is often strategic, but LLMs tend to play nice. How strategic are they really? Probing into that is key for future safety alignment.

👉Introducing CoBRA🐍, a framework that assesses strategic language.

Work with my amazing advisors @jessyjli.bsky.social and @David I. Beaver!
