What do SEM and criminal investigations have in common?

I really, really believe in using non-scientific examples and comparisons to teach statistics. In this post, I will show you how I see comparisons between criminal investigations and scientific investigations. Specifically, after a summer spent going down a true-crime rabbit hole, I think that criminal investigations and court cases are sort of like SEM.1. Investigators and statisticians are sometimes forced to use tangible evidence to infer about intangible variables and concepts.2. An evidence board is basically a path diagram, right?Don't worry, I made a whole PowerPoint to explain. And maybe you can use the PowerPoint the next time you teach SEM.
