David and Drew unpack six organizational uses of injury metrics — from controlling work and motivating the workforce to self-promotion and risk signaling — before distilling these into four broad symbolic meanings: management control, image management, risk management, and trust in leadership. The episode reveals that injury rates are unstable signs whose meaning shifts depending on context, observer, and organizational culture. Understanding the emotional and symbolic dimensions of these metrics is shown to be essential for any safety professional seeking to challenge, replace, or engage more honestly with the measurement systems that shape how safety is understood and acted upon in their organization.

These criticisms are fairly easy to understand, and there are so many of them from so many different directions that people know these criticisms and believe some of them. But injury rates still happen. That puzzle needs to be understood."
Drew Rae: "Something could be a bad measure of whether you're actually safe, but a good measure of how your injuries are affecting these other types of risks that you're facing."
Drew Rae: "Safety activities are driven by affect — emotion matters. We do things in safety because we are afraid, or because we are uncertain, because we are anxious. And our safety activities change those emotions."
Drew Rae: "We've now got both pieces of the puzzle. We know that they don't work objectively, and we know that people keep using them because of these symbolic meanings. That's pretty much the full story about injury rates."
David Provan: "Be curious about the meaning that's being ascribed to the injury rates in your own organization."
