Thanks! I imagine we'd see similar results in the Novelty Challenge that when experts are reliable we can fine-tune LLMs to be reliable but experts may only be reliable in some disciplines/settings and less reliable in others.
Very cool challenge!!

When are LLMs-as-judge reliable?
That's a big question for frontier labs and it's a big question for computational social science.
Excited to share our findings (led by @aakriti1kumar.bsky.social!) on how to address this question for any subjective task & specifically for empathic communications

This taxonomy offers a shared language (and see our how to guide on arXiv for many examples) to help people better communicate what looks or feels off.
It's also a framework that can generalize to multimedia.

Based on generating thousands of images, reading the AI-generated images and digital forensics literatures (and social media and journalistic commentary), analyzing 30k+ participant comments, we propose a taxonomy for characterizing diffusion model artifacts in images

We examine photorealism in generative AI by measuring people's accuracy at distinguishing 450 AI-generated and 150 real images
Photorealism varies from image to image and person to person
83% of AI-generated images are identified as AI better than random chance would predict

Large scale experiment with 750k obs addressing
(1) How photorealistic are today's AI-generated images?
(2) What features of images influence people's ability to distinguish real/fake?
(3) How should we categorize artifacts?

At a high level, it depends on:
- human expertise
- human understanding for what the AI system is capable of
- quality of AI explanations
- task-specific potential for cognitive biases and satisficing constraints to influence humans
- instance-specific potential for OOD data to influence AI

Real vs. fake: Can you spot AI-generated images?
Some images generated by artificial intelligence have become so convincingly real that there is no surefire way to spot the fakes. But experts say there are still things we can try to detect fakes.

This paper explores how language shapes behavior. Our contribution, however, is not in testing specific hypotheses- its in generating them (using #LLMs + #ML + #BehSci)
But how exactly?
