Very difficult indeed. We study these types of issues empirically:

🚨 New preprint 🚨

Across 3 experiments (n = 3,285), we found that interacting with sycophantic (or overly agreeable) AI chatbots entrenched attitudes and led to inflated self-perceptions.

Yet, people preferred sycophantic chatbots and viewed them as unbiased!

Cool work! Did y'all look at how people update when they discover AI makes an error?

Our new paper finds that AI can overcome partisan #bias

We find that AI sources are preferred over ingroup and outgroup sources--even when people know both are equally accurate (N = 1,600+): osf.io/preprints/ps...

Really cool work led by @hongkai1.bsky.social ✨ observational and experimental studies finding that differentiation helps explain the evolution of negative discourse online!

Joshua Conrad Jackson @joshcjackson.bsky.social · 13d

🚨New preprint🚨

osf.io/preprints/ps...

In a sample of ~2 billion comments, social media discourse becomes more negative over time

Archival and experimental findings suggest this is a byproduct of people trying to differentiate themselves

Yet again, machine learning — even gussied up via the transformer architecture — encodes and reinforces societal biases.

This study reveals that LLM-based peer review relies heavily on author institution in its decisions.

Prestige over merit: An adapted audit of LLM bias in peer review

Large language models (LLMs) are playing an increasingly integral, though largely informal, role in scholarly peer review. Yet it remains unclear whether LLMs reproduce the biases observed in human de...

I suspect we are already at the point where students view writing a dissertation without LLMs the same as us millennials viewed writing a dissertation on a typewriter, i.e., unfathomable. No value judgment, just interesting how quickly that escalated.
