Less than a week until the PolMeth application deadline! I'm on the program committee, and look forward to reviewing submissions. If you're developing new methods or applying sophisticated approaches to substantive political questions, submit your work. Funds are available to support some attendees.

A shitty map created by ChatGPT5.  it purports to be US States with an R in their name, but it's wrong and dumb and worthless just like LLMs.

A shitty map created by ChatGPT5. it purports to be US States with an R in their name, but it's wrong and dumb and worthless just like LLMs.

My goto is to ask LLMs how many states have R in their name. They always fail. GPT 5 included Indiana, Illinois, and Texas in its list. It then asked me if I wanted an alphabetical highlighted map. Sure, why not.

What I hate about this is that, for GPT-6, they're going to do

if "blueberry" in prompt:
print("there are two Bs in blueberry")

and claim it is now more intelligent than GPT-5.

The fact that ChatGPT can produce an essay about the history of blueberries but can't count the letters is a great example of how it is a text producing machine not a reasoning machine.

In this project, randomly allocating students to teams permitted identifying causal effects of co-membership.

Thanks to Sarah Gordon, Wayne Baker, Jose Uribe, and Cassandra Chambers for bringing me on!

Do women politicians address violence against women more effectively?

It would be a big deal if they do!

It would provide (perhaps more) reason(s) to elect more women!

But I'm skeptical that this study actually shows that women politicians reduce violence against women.

Here's one reason why:

I understand why people are theorizing that the Grok/South Africa thing was caused by a system prompt, but what it really reminds me of is Golden Gate Claude, which involved artificially amplifying some model features. I am so curious about how this happened. www.anthropic.com/news/golden-...

A group of men and women pose for a photo in a classroom or conference room. The men, dressed in a mix of formal and casual attire, stand on the left, while the women, mostly wearing black abayas and niqabs, stand on the right. A banner with Arabic text and a logo is visible on the wall behind them. The room is furnished with tables, chairs, and various personal belongings, such as bags and water bottles. The setting suggests a professional or educational gathering.
