Ep. 267 - Addressing Data Fraud in Nutrition Science

Iron Culture

The holy trinity is back and holy smokes do we have a Holy Ghost of an episode! First, to kick things off the crew discusses the recent “March madness” of powerlifting that just finished: IPF European Champs, the UK Arnold, and Powerlifting America Nationals. Some absolutely stunning performances occurred all over the world in powerlifting and it seems the rising tide of talent has no end. Then we get into the meat - or should I say the bottomless soup - of the episode. While fraud in research is exceedingly rare, it does happen, and unfortunately, more common issues such as p-hacking are a far more prevalent issue. What is to be done in situations like this? One tool, as the Erics discuss, is replication.
