I'm a computer science professor at Princeton. I write about AI hype & harms, tech platforms, algorithmic bias, and the surveillance economy.

I've been studying decentralized social media since the late 2000s, so I'm excited to use and write about Mastodon at the same time.

Check out this symposium on algorithmic amplification that I'm co-organizing: https://knightcolumbia.org/events/optimizing-for-what-algorithmic-amplification-and-society

The "ChatGPT has a liberal bias" paper has at least 4 independently fatal flaws:
– Tested an older model, not ChatGPT.
– Used a trick prompt to bypass the fact that it actually refuses to opine on political q's.
– Order effect: flipping q's in the prompt changes bias from Democratic to Republican.
– The prompt is very long and seems to make the model simply forget what it's supposed to do.
By @sayashk and me, summarizing our analysis and a separate one by Colin Fraser. https://www.aisnakeoil.com/p/does-chatgpt-have-a-liberal-bias

People have been posting glaring examples of ChatGPT’s gender bias, like arguing that attorneys can't be pregnant. So @sayashk and I tested ChatGPT on WinoBias, a standard gender bias benchmark. Both GPT-3.5 and GPT-4 are about 3 times as likely to answer incorrectly if the correct answer defies gender stereotypes — despite the benchmark dataset likely being included in the training data. https://aisnakeoil.substack.com/p/quantifying-chatgpts-gender-bias

OpenAI mitigates ChatGPT’s biases using fine tuning and reinforcement learning. These methods affect only the model’s output, not its implicit biases (the stereotyped correlations that it's learned). Since implicit biases can manifest in countless ways, OpenAI is left playing whack-a-mole, reacting to examples posted on social media.

This is the latest in the AI Snake Oil book blog by @sayashk and me. Writing this blog alongside the book has been really fun. I'll probably do something like this for all future books! Thank you to everyone who subscribed. https://aisnakeoil.substack.com/

We're at over 1,000 registrations for the @knightcolumbia algorithmic amplification symposium this Friday & Saturday. We're lucky to have an all-star cast of speakers. In-person registration is closed/waitlisted, but you can still register to attend online: https://knightcolumbia.org/events/optimizing-for-what-algorithmic-amplification-and-society

Who do so many people seem unaware of the mass exodus from Twitter?

Social media feeds are engines for distorting our social understanding. But we can push back against the algorithm, with a simple automated out-of-office message on Twitter (how-to included).

This post explains the science of social influence that allows Twitter to maintain an illusion of a full room, how to change that, & why we need industry-independent science for our digital environments.

@natematias Totally agree about social media's distorting influence!

If there's quantitative evidence of a mass exodus, I'd be curious to see it. If people are leaving en masse, it doesn't look like they're ending up on Mastodon.
