Why do people devalue empathic responses believed to be edited by AI? Because empathy is a predictive social signal: genuine human empathy updates expectations about closeness and social trust. The signaling function of empathy collapses when it is cheaply outsourced. www.cell.com/trends/cogni...

How do people reach agreement on public health issues? Using fMRI hyperscanning + NLP, we found that when conversation partners aimed to compromise rather than persuade, they explored a wider range of mental states and topics — and ended up agreeing more. psycnet.apa.org/record/2027-...
