Prediction, Risk, and Illusion
摘要
Several forms of illusory understanding in science are identified by Shiffrin et al. (2026). We focus on one they emphasize: the illusion that predictive success implies causal insight. Their diagnosis, we argue, lacks a criterion for when incomplete understanding becomes illusory, conflating predictions that warrant confidence with those that do not. We propose that what separates warranted confidence from illusion is not causal completeness but the risk structure of the prediction: whether the model could have failed had the hypothesis been wrong. The question shifts from “how complete is the causal story?” to “how severe was the test?”.
