Human error is never the root cause — it's just the starting point. Here's how HOP reframes incident investigation and why blame culture is killing your safety program.
Every time a worker gets hurt, the first question most organizations ask is: Who did it?
That question is wrong. Not just ethically — it's operationally wrong. It produces the wrong investigation, the wrong corrective actions, and the same incident six months later with a different name on the report.
Human and Organizational Performance (HOP), developed by safety researcher Todd Conklin, reframes the entire model. And once you understand it, you cannot unsee it.
When your incident investigation ends with "employee failed to follow procedure," you haven't found the root cause. You've found the last human who touched the system before it failed.
HOP asks a different question: Why did it make sense for that person to do what they did, in that moment, given the conditions they were working in?
That reframe is everything. It moves the investigation from blame to system design. And system design is something you can actually fix.
Heinrich's Triangle tells you that for every fatality, there are roughly 300 near-misses underneath it. But here's what most EHS programs miss: that number only holds if people are actually reporting near-misses.
When workers have learned that reporting a near-miss means getting written up, counseled, or blamed — they stop reporting. The triangle collapses. The data disappears. And the incidents keep happening.
HOP Principle 5 — response matters — is the root cause of your near-miss reporting gap. If leadership responds to bad news with punishment, the bad news stops flowing. And you lose the only early warning system you had.
Here's what a HOP-aligned investigation looks like in practice:
There's a missing variable in most EHS programs: psychological safety. Amy Edmondson's research — and Todd Conklin's field work — converge on the same finding. People perform safer behaviors when they believe they will not be punished for speaking up.
Without psychological safety:
HOP is the framework that breaks the plateau. It replaces the question "who do we punish?" with "what do we fix?"
You don't have to throw out your incident investigation process. You have to ask different questions at the end of it.
Before you close the corrective action:
Blame fixes nothing. Systems fix incidents. That's the HOP principle — and it's the one your investigation process is probably missing.
At EHS, Inc., Gerty helps safety teams build the documentation infrastructure that makes HOP-aligned investigations possible — near-miss tracking, leading indicator dashboards, corrective action workflows, and training records that prove your program is changing behavior, not just documenting it.
