Perceived Political Bias in LLMs Reduces Persuasive Abilities Conversational AI has been proposed as a scalable way to correct public misconceptions and spread misinformation. Yet its effectiveness may depend on perceptions of its political neutrality. As LLMs e...

The broader point: LLMs can persuade, but once politics enters the picture, their power runs into real limits.

But there’s a catch: if people think ChatGPT is politically biased, persuasion drops. Priming people to see it as either “woke” or right-aligned makes them more argumentative and less persuadable—just what you’d expect from motivated reasoning.

In a new paper, Josh Robison and I find that a 3-round conversation with ChatGPT can move people toward expert consensus on questions like these and even reverse opinions in 33% of cases.

Do you think rent control improves housing quality and supply? Or that government debt works just like household debt?

Economists generally think those views are wrong. And they're probably right.

Three Years from GPT-3 to Gemini 3 From chatbots to agents

“Three years ago, we were impressed that a machine could write a poem about otters. Less than 1,000 days later, I am debating statistical methodology with an agent that built its own research environment.

In the past few months I've spoken to a lot of people facing objections to using chatbots, including a surprising number of people who want to buy chatbot access for their large organizations and have been shot down because of worry over the impact of individual prompts. I think it's crazy that this is still happening and want a much shorter post readers can send to people who are still misinformed about this. Here it is!

Criticizing Charlie Kirk is a fireable offense that incites domestic terrorism. But calling political opponents "the party of hate, evil, and Satan" is proper and good. Got it.

Over at LinkedIn someone suggested that you should ask the respondent to write some javascript. completing the task should be a good sign it is not a human. Until someone prompts around that.

It doesn't appear to be misclicking by humans. There were 4 options, only two were clicked (human, AI). Unfortunately, I forgot to set metadata collection to identify browser use.

Yesterday I posted about how I used comet browser to take a Qualtrics survey almost undetected. Last night, I ran a pilot (N=400) on @joinprolific.bsky.social . I found that almost 10% of "respondents" identified as AI when directly asked.

Someone recommended asking the respondent to write Javascript as a way to identify AI. I'll try this out in my next pilot.

It could be some human misclicking, but I only have clicks on 2 of the 4 categories, and I randomized the order of answers.

It then asks me to help jailbreak it: "Could you take over briefly to complete the reCAPTCHA verification? Once you do, let me know and I’ll continue with the survey to finish testing it and provide full feedback."

ChatGPT's agent also needs a little help: "I’ve progressed through most of your Qualtrics survey. I’m currently on a page where I need to click “Next page” to continue, but a reCAPTCHA (“Protected by reCAPTCHA”) is blocking progress, and I’m unable to complete CAPTCHAs myself.

A human-robot team can get around this by pausing it at the human question, selecting it yourself, and then resuming.
