If you are going to use terms like culture around perhaps you should rephrase "he/she is rarely completely to blame for the accident" to "there are many factors that cause accidents".
I can recommend
The Field Guide to Understanding Human Error by Sidney Dekker.
Now perhaps JimL will join the debate on profiles
- but that may be better as different thread. I hope the concept of 'culture' is not going to be abused as an euphemism for regulations.
