Unlike prior methods that operate on expected amortized attention for each individual, we also define new divergence-based measures for attention distribution-based fairness in ranking (DistFaiR), with useful properties.

We observe that metrics for fair ranking are indeed sensitive to query polarity in practice, and an adjustment to fair ranking metrics to account for query properties such as polarity.

We find that prior research in amortized fair ranking ignores critical information about queries, and treats all queries as equivalent ignoring query properties in fairness measurement. This increases the risk of *fairwashing*.

Machine learning-driven rankings, where individuals are ranked in response to a query, mediate exposure in a variety of safety-critical settings. In this work, we examine amortized fair ranking -- where relevance and attention are cumulated over a sequence of user queries.
