Ever try to make sense of a scientific study and the numbers behind it? Listen in to a lively conversation between two stats-savvy friends who break it all down with humor and clarity. Professors Regina Nuzzo of Gallaudet University and Kristin Sainani of Stanford University discuss academic papers journal club-style — except with more fun, less jargon, and some irreverent, PG-13 content sprinkled in. Join Kristin and Regina as they dissect the data, challenge the claims, and arm you with tools to assess scientific studies on your own.","last_synced_at":"2026-06-30T00:19:09.554623+00:00","page_url":"https://stenobird.com/podcast/normal-curves-sexy-science-serious-statistics-7212156"},"episode":{"title":"Bonus: Sugar Sag with Commentary","slug":"bonus-sugar-sag-with-commentary","published_at":"2026-01-12T12:00:00+00:00","page_url":"https://stenobird.com/podcast/normal-curves-sexy-science-serious-statistics-7212156/bonus-sugar-sag-with-commentary","show_page_url":"https://stenobird.com/podcast/normal-curves-sexy-science-serious-statistics-7212156","url":"https://www.normalcurves.com/bonus-sugar-sag-with-commentary","audio_url":"https://op3.dev/e/media.transistor.fm/a8d19dc7/4d304554.mp3","summary":"While we’re on a short break between seasons, we’re revisiting some of our favorite episodes from Season 1. This week, we’re re-releasing our exploration of how your diet can affect your skin – now with added commentary! Wrinkles and sagging skin—just normal aging, or can you blame your sweet tooth? We dive into “sugar sag,” exploring how sugar, processed foods, and even your crispy breakfast toast might be making you look older than if you’d said no to chocolate cake and yes to broccoli. Along the way, we encounter statistical adjustment, training and test data sets, what we call “references to nowhere,” plus some cadavers and collagen. Ever heard of an AGE reader? Find out how this tool might offer a sneak peek at your date’s age—and maybe even a clue about his… um… “performance.” Statistical topics Confounding Correlation vs causation Measurement error / proxy variables Overfitting Plagiarism Proper citing practices References to nowhere Statistical adjustment Training and test sets Methodologic morals “When you plagiarize, you steal the errors too.” “Overdone statistical adjustment is like overdone photo filters–at a certain point it’s just laughable.” Citations Collagen turnover: Verzijl N, DeGroot J, Thorpe SR, et al.
