The study of absent-mindedness in everyday life provides ample documentation and categorization of such aspects of behavior. While human error is firmly entrenched in the classical approaches to accident investigation and risk assessment, it has no role in newer approaches such as resilience engineering.[6] Categories[edit] There are many ways to categorize human error.[7][8] exogenous versus endogenous (i.e., originating outside versus inside the individual)[9] situation assessment versus response planning[10] and related distinctions in errors in problem detection (also see signal detection theory) errors in problem diagnosis (also see problem solving) errors in action planning and execution[11] (for example: slips or errors

I'm looking for something like percentages of root cause where human error was the true root cause or a contributing factor. I plan on using it in a paper I'm writing for a psychology class.
