This research paper examines the impact of an artificial intelligence tool for materials discovery on the productivity and performance of scientists working in a large U.S. firm's R&D lab. The study exploits a randomized rollout of the AI tool across teams of scientists, allowing the researchers to draw causal inferences about the effects of the technology. The paper demonstrates that the AI tool significantly increases the rate of materials discovery, patent filings, and product innovation, but these benefits are unequally distributed among scientists. The researchers find that the AI tool is most beneficial to scientists with strong judgment skills, which involve the ability to evaluate and prioritize AI-generated candidate compounds. The study also reveals that the AI tool automates a significant portion of idea generation tasks, resulting in a reallocation of scientist labor towards judgment tasks. This reallocation, along with the increased demand for judgment skills, explains the heterogeneous impact of the AI tool on scientific performance.

Ep41. Distinguishing Ignorance from Error in LLM Hallucinations
This research paper investigates the phenomenon of hallucinations in large language models (LLMs), focusing on distinguishing between two types: hallucinations caused by a lack of knowledge (HK-) and hallucinations that occur despite the LLM having the necessary knowledge (HK+). The authors introduce a novel methodology called WACK (Wrong Answers despite having Correct Knowledge), which constructs model-specific datasets to identify these different types of hallucinations. The paper demonstrates that LLMs’ internal states can be used to distinguish between these two types of hallucinations, and that model-specific datasets are more effective for detecting HK+ hallucinations compared to generic datasets. The study highlights the importance of understanding and mitigating these different types of hallucinations to improve the reliability and accuracy of LLMs.
