When these filters interact with our cognitive biases, they create feedback loops that decouple item popularity from quality, weakening collective discovery. \u003C/p>\n\u003Cp>In this talk, Kristina Lerman will present empirical evidence from two domains. First, online choice experiments reveal that attentional biases, reinforced by ranking algorithms, reward the most visible items, so that the best items may not become the most popular. Second, large-scale analyses of bibliometric data reveal how science “finds” good ideas and people. A “rich get richer” dynamic in science (aka the Matthew effect) operates as a feedback loop, bringing more attention to the already-recognized papers and scholars. This dynamic magnifies existing social biases tied to gender and prestige, creating disparities that disadvantage women scholars and researchers with less-prestigious affiliations. Together, these results show how algorithms and cognitive heuristics interact to unintentionally tilt the playing field and distort discovery. To improve discovery and innovation, we need systems that counter these feedback loops and correct for individual biases.\u003C/p>\n\u003Cp>This talk is offered both in person and online.
