    "title": "Intuituve archeology: Detecting social transmissino in the design of artifacts",
    "subtitle": null,
    "abstract": "Human-made objects (artifacts) often provide rich social\ninformation about the people who created them. We explore\nhow people reason about others from the objects they create,\ncharacterizing inferences about when social transmission of\nideas (copying) has occurred. We test whether judgments are\ndriven by perceptual heuristics, or structured explanation-\nbased reasoning. We develop a Bayesian model of\nexplanation-based inference from artifacts and a simpler\nmodel of perceptual heuristics, and ask which better predicts\npeople’s judgments. Our artifact-building task involved two\ncharacters who built toy train tracks. Participants viewed pairs\nof tracks, and judged whether copying had occurred. Our\nexplanation-based model accurately predicted on a trial-by-\ntrial basis when participants inferred copying; the perceptual\nheuristics model was significantly less accurate. Efficient\ndesign ‘explained away’ similarity, making similarity weaker\nevidence of copying for efficient tracks. Overall, data show\nthat like intuitive archeologists, people make rich\nexplanation-based inferences about others from the objects\nthey create.",
