Large-Language Models as a Cognitive Virus

Researchers model large language model (LLM) adoption as a contagion process through social transmission. Adoption reaches tipping points where small increases trigger rapid shifts toward persistent dependence on LLMs. Populations that cross critical thresholds of adoption face potential loss of cognitive competence. Collective reinforcement and recovery cycles create nonlinear population-level transitions. Mitigation strategies reduce transmission and improve reversibility of adoption to enable cognitive protection. This framework bridges epidemiology and cognitive science to understand AI integration effects on human cognitive independence.

Short Videos, Big Self-Control Problems

A study finds that short-form video platforms cause users to watch significantly more than intended. Viewers watch 82.1% more content than they plan. The brief episode format creates constant temptation. Researchers propose solutions such as larger decision units, default viewing limits, and scheduled breaks to improve user welfare.
