Mentalizing and heuristics as distinct cognitive strategies in human teaching
Nature Human Behaviour, Published online: 26 August 2026; doi:10.1038/s41562-026-02540-2Harootonian et al. find that people switch between effortful, tailored teaching and easier, simple shortcuts, favouring shortcuts even when unhelpful. Prompting participants to reflect on learners’ limitations restores effective, personalized instruction.

For a year and a half, @carorowland.bsky.social, @lehersingh.bsky.social, Marisa Casillas, Shanley Allen, and I have been meeting to discuss whether innateness is still a useful concept to think about in studying language acquisition. Here's our take: osf.io/preprints/ps...
Title pageThe origins of language have been a persistent object of philosophical and scientific inquiry, in part
because they offer a window into the origins of thought. Classic innatist theories of language have argued
that languages share universal elements that arise because language acquisition is guided by rich,
biologically specified structures in the form of a universal grammar. However, different versions of this
hypothesis that posit substantial amounts of innate content are not consistent with recent evidence. We
review new evidence from language diversity, human interaction, and large language models (LLMs), all
of which challenge classical innatist views. Yet we believe there is still value in asking what elements of
language development are innate. In this Perspective, we integrate evidence from these three areas
towards a broader conception of innateness, one that seeks to explain both consistency and variation in
language acquisition. On this view, innateness remains a key orienting principle for understanding the
origins of language.
