Why does chatGPT make up fake academic papers?
By now, we know that the chatbot notoriously invents fake academic references. E.g. its answer to the most cited economics paper is completely made-up (see image).
But why? And how does it make them? A THREAD (1/n) 🧵
ChatGPT is based on a language model, which assigns a probability distribution over sequences of words. A rough way to think about it: Given the start of a sentence, it will try to guess the most likely words to come next. (2/n)

My take on chess.com’s (CC’s) Hans Niemann report: a thread 🧵👇
The report is good. It didn’t need to be that long for the HN case, but on the other hand it’s great that CC has publicly laid out more details about its cheat detection system, the human process behind detection/banning policies, and their broader philosophy towards cheating. 1/
What I like about this article:
- It corrects a commonly held misconception that Aboriginals in custody are more likely to die than non-Aboriginals (they're not)
What I don't like about this article:
(1/4)
- No reference to prison rates (ATSI are roughly 12x more likely to spend time in prison than non-ATSI. For women, it's 20x)
- Mentions child abuse and domestic violence in passing. But, no evidence that ATSI people have higher rates after controlling for other factors
(2/4)
