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.

What You’ll Learn 

• Why is data really presented in this industry — truth, persuasion, or something in between? 
• How charts can hide peaks or exaggerate trends 
• What error bars actually mean and why they matter 
• When to question normalized or percentage-based data 
• Signs that a dataset should be tossed out completely 
• How to read peer-reviewed papers quickly without wasting time 
• Why checking funding sources matters 
• Why asking questions doesn’t make you “anti” anything
