Consequential decisions compel individuals to strategically react in response to the specifics of the decision rule. In aggregate, these individual-level responses can disrupt the statistical patterns that motivated the decision rule, leading to unforeseen consequences. In this breakout session, we will give an introduction to the area of strategic classification, with a focus on limitations of the standard models of agent behavior. We will then have a discussion about applications where strategic adaptation is observed, potential approaches for modeling strategic agents, and connections to other domains.
