Safety science has come a long way in understanding behavior. However, a few things need to be learned about the behavior of safety professionals. The best organizations are systematic about safety issues and perform audits and checklists meticulously. But they often are blinded by the audit.
Safety science is not good at tracking small changes and noticing when things are slipping inexorably but slowly. When something bad happens, it is sometimes because the reality on the ground no longer matches the audit instrument.
