The October 2018 issue of Significance is out in print and digital formats. In this issue, we explore the use of statistics in court. Judges and jurors are often asked to make sense of statistics. But data, probabilities, and uncertainties are easily misunderstood or misused by those not trained to deal with them. Is education the answer? Or is greater oversight required? Nick Thieme considers the options for the US legal system.

Continuing the legal theme, Jonny Jacobsen takes us back to the 1990s, when British miners were fighting for compensation for diseases linked to coal dust exposure. Epidemiology and statistics were essential to the miners’ case, so defendants sought to cast doubt on the data—and it fell to Jonny’s father, the late Michael Jacobsen, to argue that the research was sound. With a high concentration of cases of “black lung” disease recently reported among miners in southwest Virginia, this historical account is a timely tale.

Also in this issue:

• Letisha Smith, winner of the 2018 Award for Statistical Excellence in Early-Career Writing, uses machine learning to help streamline her meal plans.
• Andrew Gelman offers five recommendations for dealing with fundamental ethical dilemmas in statistical practice and communication.
• Diana Scarrott presents a brief history of Zachary Macaulay, the “brilliant statistician” who fought to end slavery in the British colonies in the 1800s.
• In an excerpt from his new book, The Perils of Perception, Bobby Duffy argues that our brains are partly to blame for our misperceptions about society.
