Jury selection can now pick representative groups using a new math trick

A new method for selecting groups of items, like potential jurors, has been developed. It involves one side dividing the population into equal parts, and the other side picking one item from each part. This ensures the final group better reflects the whole population.

This new method, called the Quantile Mechanism, offers a way to create more representative groups when selecting items from a larger population. It works by having one party divide the population into equal segments and another party choose one item from each segment. This approach is shown to be the best possible for ensuring representation, which could change how juries are selected, how legal cases are managed across different districts, and how committees are formed.
