How to deal with the survey-taking AI agents that threaten to upend social science Researchers need new bot-detection strategies that exploit the limits of human reasoning rather than AI weaknesses.

Online surveys are on their way to the grave. Are we working on alternatives? Is it time to start proctoring every survey taker?

Current main bandwagon in AI x Psychology research has been embedding questionnaires with transformers. Are we ready to answer the question of whether transformers actually uncover the latent psychological dimensions vs. they are just useful in pinpointing any text differences?

Proud to share what I've been working on for the last half a year - a method to statistically assess and explain differences in the perceived meaning of concepts based on small samples.

Allow me to introduce the Supervised Semantic Differential

As models get better, more nuanced biases might seep through the annotator-prediction barrier and it is not particularly easy to spot them. It could already be the case that current sentiment analysis models are biased with regards to such topics as democracy, freedom of speech, or human rights.

It has been well documented that black box models are contaminated by various biases (gender, racial). Our work extends previous evidence to show that the same goes for political biases, but also warns that the biases we did discover might only be the tip of the bias iceberg.

Researchers have to realize the risks of using black box models and take robust measures to strengthen the validity of their conclusions.

New BSky Update: fake accounts
@jaceksutryk.bsky.social is an account of "supposedly" the president of Polish city Wroclaw, which added me here just after I posted my handle to one of Polish political shitposting groups. Beware who you follow. The high trust society we are building might backfire.

There are people on the www who love destroying wholesome places. It's fascinating in a way, as most of them keep their persona irl. Probably because of well implemented checks and balances

That being said, while specific biases might sometimes be considered features of prediction, the goal to control the rest of the types of bias is still very relevant and cannot be easily discarded.

Ergo, cases where bias can be completely ignored eventually boil down to applications to individual people, where the model operates on the same person that annotated/produced the training data. Such cases are obviously absurdly unrealistic.

However, even then that doesn't mean that any bias goes. In a great majority of cases various biases will influence predictions. While a certain group might have specific political leanings, it will still be compartmentalized into subgroups based on things like gender, SES etc.

Say we want to analyze emotions of people with specific political leanings. Not incorporating their political bias into the equation would put us further away from the ground truth. Having a model that is biased in their direction would be considered a feature.

It's obviously true that humans are biased - otherwise m there would be no bias in ML models. More so, in some cases the latter bias is even recommended. But in most cases an unbiased model is what we want.

Read more to know when bias is a feature, and when it is a bug.

The Semantic Propagation Graph Neural Network (SProp GNN) leverages this approach to achieve:
โœ… Superior performance to lexicon-based models like VADER.
โœ… Near-transformer accuracy in emotion prediction.
โœ… Bias-resistant predictions across English & Polish texts.

Why it matters:
โ€ข Eliminates biases like those found in transformers.
โ€ข Improves fairness and generalization.
โ€ข Creates interpretable and ethical AI systems.

Itโ€™s the foundation of the SProp GNN, a new graph neural network Iโ€™ve developed.

What is Semantic Blinding?
Itโ€™s a technique that โ€œblindsโ€ AI models to specific words or concepts, focusing only on syntactic structures and word-level emotional cues. This ensures models donโ€™t associate emotions with biased language or concepts.

Budapest is an amazing city (and has a lot of my favorite Art Nouveau architectural diamonds like the Pรกrisi Udvar seen on the pictures)

It was a pleasure to take part in the 2nd Budapest Methods Workshop on LLMs. Thanks @miklossebok.bsky.social for invitation ;)

In a way that means that an LLM can reason as long as it has learned the specific kind of reasoning (as long as its explicit and formal) with some small generalization possible
