A minority of physicians actually read the original study, and of those who read the study, even fewer have any real idea of the statistical ingredients used to make the study. Imagine not knowing whether the sausage you just ate contained rat droppings. At least there is some hope the tongue may provide some objective measure of the horror within.

Data that emerges from statistical black boxes typically have no neutral arbiter of truth. The process is designed to reveal from complex data sets, that which cannot be readily seen.

Many Ways of Skinning a Statistical Cat

By SAURABH JHA MD Saurabh Jha has a conversation with Professor Brian Nosek

In this episode of Firing Line, Saurabh Jha (aka @RogueRad), has a conversation with Professor Brian Nosek, a metaresearcher and co-founder of Center for Open Science.

They discuss the implications of this study, which showed that there was a range of analytical methods when interrogating the database to answer a specific hypothesis: are soccer referees more likely to give red cards to dark skinned players? What is the significance of the variation? Does the variation in analysis explain the replication crisis?
