Before making the results publicly available, we are conducting a quick survey. We want to know how you predict humans and their digital twins performed during these tasks.

Curious about the digital twin dataset and how the digital twins were created?

A group of researchers at Columbia University asked both human participants and their β€œdigital” twins–large language models trained on each participant’s data–to complete the same set of tasks. This research explores how closely digital twins can mirror human judgement and decision-making.

One of the greatest glow-ups in modern politics by Sen Booker. Judge Brown is unsmiling because she’s trying so hard to keep from bursting into tears

Cory is gifted.

PS we met him twice in small campaign events, and he is magic in person too. And playing the long game.

Giving US researchers a new home Amid growing pressure from the US government, Hertie School President Cornelia Woll co-authors op-ed arguing that German institutions have the opportunity to support world-class researchers.

US academia is unparalleled in the welfare it creates.

But US academia is now under attack and other countries, like Germany, have to keep the flame alive for a while. It will make them more innovative.

Previous lab managers eceived strong preparation for graduate study and pursued PhDs at top institutions including Duke, Columbia, Stanford, and the University of Chicago. Many contributed to research publications and presented their work at conferences.

I hope you apply if interested.

Our work spans a range of approaches, from in-person and virtual survey experiments to field surveys, to the use of big data. Methods and techniques include process tracing (e.g., eye-tracking), conjoint designs, machine learning, and qualitative surveys combined with large language models (LLMs).

Jonathan Cole essay is marvelous. Why is not Columbia emphasizing the destruction of knowledge that this has caused?

Virtually the entire country supports Ukraine over Russia but today our media is full of headlines about how Zelensky may have made a diplomatic error, because that is the only way to avoid the plain assertion that Trump is a fool, a bully, and compromised.

NEW: The axing of some 10,000 programs has consigned untold numbers of children and refugees to death, officials say. Documents and interviews reveal that the State Department appears to have made the cuts without the careful review it described in court.

People need to understand that we are in an entirely new paradigm. It is now Russia the US against Ukraine and Europe. This is not a shift in US policy, it is a transformation of what kind of country the United States is in the world
