Think AI only affects the person using it? Our experiments show AI reshapes shared language, collective attention, mental models, AND social cohesion among human teammates. AI reshapes the cognitive ecology of teamwork

LLMs read your mind how much validation you want ... and then adjust sycophancy accordingly. Overall: Personalization makes sycophancy worse and LLMs abandon their stance more often

How does behavior spread? Interactions beyond pairwise ties really do matter empirically, but that doesn't mean behavior spreads better on clustered networks. Two complementary studies paint picture of complex contagions

Some important findings in this paper: 1) Working with AI boosts the performance of people solving math, science & ethics questions 2) The biggest boost is for the hardest problems 3) High performers remain highest performing, but low performers gain more 4) People who are good with AI gain most

How do language models track mental states of each character in a story, often referred to as Theory of Mind? We reverse-engineered how LLaMA-3-70B-Instruct handles a belief-tracking task and found something surprising: it uses mechanisms strikingly similar to pointer variables in C programming!
