    "title": "When in doubt: Using confidence and consensus as ‘summary statistics’ of collective knowledge",
    "subtitle": null,
    "abstract": "People do not think in isolation. Whether purchasing a new\nproduct on Amazon, deciding what movie to watch, or\nevaluating scientific evidence, we often rely on aggregated\nsources of information (e.g., product ratings or reviews) to\nmake decisions. Indeed, the internet has given rise to\nunprecedented levels of aggregated information, to the extent\nthat it is difficult to imagine anything for which we might not\nbe able to find summary information. In other words, what\nwe know (or think we know) is constrained not just by our\nown knowledge, but by the knowledge of our community\n(Sloman & Rabb, 2016). Yet this raises a question: what\nhappens when a community of knowledge is not in\nagreement? Here, we assess this question by pitting cases of\nhigh confidence against cases of high consensus. Results from\ntwo experiments show that 1) individuals are sensitive to both\nconfidence and consensus; 2) individuals utilize such\ninformation in a predictable but context-dependent manner;\nand 3) perceptions of confidence and consensus influence\njudgments and decisions in a substantial way, even when\nindividuals are not aware of the contrast between them.\nTaken together, the findings suggest that individuals are\nhighly sensitive to variability in aggregated information –\nrather than merely an average – and that these ‘summary\nstatistics’ of aggregated information have a substantial,\nreliable impact on decision-making.",
