## TL;DR

The paper argues that using lotteries instead of decision thresholds can lead to fairer outcomes in decision-making processes.

## Contribution

It introduces a new argument for using lotteries as a fairer method when decision criteria are arbitrary and highly standardized.

## Key findings

- Decision thresholds can be unfair when they rely on arbitrary or overly standardized criteria.
- Lotteries offer a fairer alternative by reducing the impact of arbitrary decision-making.
- The paper addresses and refutes common objections to using lotteries in fair decision-making.

## Abstract

This paper defends the role of lotteries in fair decision-making. It does so by targeting the use of decision thresholds to convert algorithmic predictions and classifications into decisions. Using an account of fairness from John Broome, the paper argues that decision thresholds are sometimes unfair, and that lotteries would be a fairer allocation method. It closes by dealing with two objections. First, it deals with the objection that lotteries should only be used to break ties in cases where individuals’ claims are equally strong. Here, the paper gives a new argument for Broome’s view, targeting decision criteria that are arbitrary and highly standardized. It then defends the arguments of the paper against the objection that lotteries are not morally superior to other methods of arbitrary choosing.
