This March, readers of Nature were greeted by the headline "Scientists rise up against statistical significance." More than 800 signatories had joined in a call to retire the term "statistically significant," and the case was argued in 43 articles published in a special issue of The American Statistician the same week. What's up, and what's next? Nicole Lazar is a leader in the movement away from hypothesis testing and arbitrary thresholds in scientific statistics. Her work with brain-imaging data is published in psychology journals, where reliance on p-value thresholds has been a source of controversy and confusion for years. She will join us for a discussion of the crisis in inference, and the related challenge of communicating the meaning of research results in a post-p-value world.
