EP #141: Concrete Data - How to Spot the BS

Most people believe the chart on the screen — Dr. Jon explains why you shouldn’t. If you’ve ever sat in a conference session staring at a chart and wondering whether you’re seeing real data or a dressed-up story, this episode is for you. Dr. Jon Belkowitz breaks down how data in the concrete industry is often stretched, normalized, cherry-picked, or misleading — and how to spot it before making decisions that affect a structure’s performance. We get into why people present data, what questions you should ask before trusting it, what error bars mean, and when it’s time to ask tougher questions. This conversation also touches on motivations, funding sources, normalized datasets, Purdue-Pharma-style chart tricks, and why peer review still matters.
