An MIT Media Lab study used EEG to track what happens in the brain when people write with ChatGPT rather than on their own. Fifty four students completed essay tasks while wearing electrode caps. One group used ChatGPT, one used a search engine, and one used no tools. Across sessions, the ChatGPT group showed the weakest neural connectivity in networks linked to memory, attention, and analytical work. They also had more trouble recalling what they had just written and produced more generic prose. The authors describe this as a kind of cognitive debt: the tool does the synthesizing, and the brain stays quieter [1].

The same experiment points to a better order of use. Students who first wrote unaided and only later switched to ChatGPT showed stronger recall and more widespread brain activity than students who started with the model and then had to work alone. In other words, the model helped more when it scaffolded thinking that was already underway than when it replaced that thinking from the start. The practical lesson is not that large language models should be banned. It is that they work best as a second pass, after the writer has already done the hard part of forming and remembering an argument [1].

Punjabi Bagh Club Road*

[Vasudha Chopra @EconChopra]

Yesterday, I stopped at a red light before the zebra crossing—like we’re supposed to. A man furiously banged my car with his hands. Road rage is terrifying, especially when you’re trying to follow rules. We must do better. @DelhiPolice @dtptraffic @TransportDelhi @nitin_gadkari

Details of the incident:

This happened on June 15, between 4:23 PM and 4:27 PM, on Club Road near Cloud 9 Hospital, Delhi.

[Vasudha Chopra @EconChopra]

We all deserve to feel safe while simply following the rules.

His vehicle’s license plate is visible in the photos I’ve attached. I request the authorities to retrieve the CCTV footage from the traffic cameras in that area during the specified time to identify and take action against him.

Attended the 2nd LEO conference at @PlakshaUniv organised by @prakarsh9 . Very well organised and now a regular event on the Indian conference calendar. Heard interesting papers by senior and junior researchers. #EconTwitter

Will automation replace jobs? Yes, but it depends on your skill level and immigrant status!

At WEIRD Talks, we hosted @RonitMukherji who shared a thought-provoking talk on the complex ripple effects on how automation impacts labor demand in the US.

Got a chance to present my research on structural variation in three generation red oak pedigree at #PAG31. What a place to be at to dive into the world of #genetics, #genomics and state-of-the-art #biotechnology tools.

If you don't interrupt speakers at the title slide, is it even an econ seminar?

@egodial Hahahhaa. Now there’s a witty reply I don’t have a response to yet.

“Overtime, I have come to understand that being an economist doesn’t necessarily equip you with the ability to make accurate assumptions in real-life situations”

@_FreedomFly_ Haha. Right. Well actually I wrote this ;)
