Chatbots can persuade people to stop believing in conspiracy theories
The internet has made it easier than ever before to encounter and spread conspiracy theories. And while some are harmless, others can be deeply damaging, sowing discord and even leading to unnecessary deaths.
Now, researchers believe they’ve uncovered a new tool for combating false conspiracy theories: AI chatbots. Researchers from MIT Sloan and Cornell University found that chatting about a conspiracy theory with a large language model (LLM) reduced people’s belief in it by about 20%—even among participants who claimed that their beliefs were important to their identity
The findings could represent an important step forward in how we engage with and educate people who espouse baseless theories. Read the full story.

Google’s new tool lets large language models fact-check their responses
The news: Google is releasing a tool called DataGemma that it hopes will help to reduce problems caused by AI ‘hallucinating’, or making incorrect claims. It uses two methods to help large language models fact-check their responses against reliable data and cite their sources more transparently to users.
What next: If it works as hoped, it could be a real boon for Google’s plan to embed AI deeper into its search engine. But it comes with a host of caveats. Read the full story.

Neuroscientists and architects are using this enormous laboratory to make buildings better
Have you ever found yourself lost in a building that felt impossible to navigate? Thoughtful building design should center on the people who will be using those buildings. But that’s no mean feat.
A design that works for some people might not work for others. People have different minds and bodies, and varying wants and needs. So how can we factor them all in?
To answer that question, neuroscientists and architects are joining forces at an enormous laboratory in East London—one that allows researchers to build simulated worlds. Read the full story.

The big story
AI hype is built on high test scores. Those tests are flawed.
August 2023
In the past few years, multiple researchers claim to have shown that large language models can pass cognitive tests designed for humans, from working through problems step by step, to guessing what other people are thinking.
These kinds of results are feeding a hype machine predicting that these machines will soon come for white-collar jobs. But there’s a problem: There’s little agreement on what those results really mean. Read the full story.
