RT by @EU_ScienceHub: "#AI always pushes out #outliers, which is anyone who’s not a white middle-aged man. So anyone in the audience right now who’s not a white middle-aged man is being treated #unfairly by AI systems.

That is the rule that we find when we #audit AI systems” - @gemmagaldon at #ESPAS

Food for thought #Samples from higher #paleolatitudes were on average smaller, but contained #outliers with the largest #sizes, highlighting the need to analyze entire #distributions. #Lithology and #collection differences need to be accounted for when evaluating #size differences across #space (#polar #gigantism) and #time (#Lilliput #effect). Similarly, differences in #facies may affect #species #determination
