I'm a search engine researcher. I tweet about information retrieval (IR) and uni work. I'm at RMIT University, these are my personal opinions.

I enjoyed the paper because it highlighted how much people use search for "do it yourself" fact checking. This is a topic IR researchers don't examine enough.

Searching also caused people to trust more true news from low quality news sources.

The way people searched seemed to impact the likelihood that they mistook fake news for true news.

I suspect one of the reasons why so many people were included in the crowd sourcing studies was to bump up the power of the study.

The authors run five extensive crowd sourcing studies collectively drawing on the responces of >14K people. Each study examined the question from different angles. Each found searching can make people more likely to believe false information. However, the effect is small.

On the #SIGIR2025 list of accepted papers, the word "LLM" appears more frequently than the word "the". I may need to revise my stopword list :) https://t.co/1xKB4Zq5PI

If you were a fan of @BlinovaValeriia's 2023 WikiHowQA ACL paper https://t.co/amzo1htYIV, you might be interested to hear that the dataset from that work is now available for open download.

Someone just reminded me of this lecture I gave in 2009 that described the evolution of Google Search from 1999 to 2009. People who are interested in how our search systems work might find this interesting. It touches on disk-based serving systems, in-memory indices,

RAG - why use "retrieval" in the acronym and not "search"? Then again would we be as excited about doing SAG?

Yup, current search infrastructure assumes human users, optimizing for short keyword queries and millisecond response times. AI agents have fundamentally different retrieval patterns. My thoughts on this shift in a thread 1/
The implications are profound. We need to build infrastructures that are agent-first rather than human-first. This requires reimagining the entire software development lifecycle (big blog post on this forthcoming).

Got a chance to look at this excellent review paper, a fine piece of work!
Check out our new paper w/ ChengXiang Zhai, in which we explore the role user simulation plays in the era of Generative AI, from modeling user behaviour to generating synthetic data to evaluating AI systems: https://t.co/qZDwZuIajL
