Dear subscribers,

I had every intention this weekend of putting together this week’s cocktail video and a short preview of Chapter 4.

Unfortunately, Sunday morning, I experienced my first exercise-related debilitating injury, which you can read about in an article I posted in Matt’s Fitness Corner on LinkedIn. I’m recovering, but my limited range of motion as well as my muscle relaxers make a situation unconducive to creating this month’s cocktail video.

But, I haven’t forgotten about you, and I want to give you something.

First, about Chapter 4…

Chapter 4 drops next week on Tuesday, October 20 at 6am EDT. Free and paid subscribers will have access to the full chapter, and paid subscribers will get the audio version dropping shortly after. That is one thing I should be able to accomplish despite my injury…

I won’t lie, Chapter 4 is short, but it’s a transition chapter that sets us up for the rest of Section II: The Blueprint (Models and Mechanisms). We start this section by discussing the definition crisis, the one where the entirety of the safety profession seems to be unable to come to a consensus on how to define safety, as well as related concepts.

If we can’t even define safety, how could we possibly start to measure it?

We’ll walk through some recent evidence from a massive study that illustrates just how extensive is this lack of consensus. We’ll also introduce the concept of the theory of change, and why it is so so critically important for all of us to use one of those. Of course, we’ll dive deeper into that later in the book, as well.

Chapter 4 is eye-opening. Buckle up.
