Researchers have developed a theoretical framework for "performative learning," where predictions influence the outcomes they are meant to forecast. This theory explores how models generalize when their predictions affect the data they are trained on, considering scenarios where predictions impact only existing users or the entire population. The analysis reveals a trade-off between a model's ability to alter the world and its capacity to learn from it, suggesting that greater influence on data can diminish learning effectiveness. The study also proposes methods to enhance generalization by retraining on performatively distorted samples, illustrated with a case study on German labor market data. AI
