The problem again is that it really doesn't lead anywhere. One of the best attempts at what you are describing is in the Just Culture algorithm. In that, we recognize three categories, error, at-risk and reckless. Consider each of these in this context:
It leads us to many places,
if followed in the matter in which I described it in my first post.
An error is considered an unintentional act. Can you avoid errors by just paying more attention? There is no evidence that this is true. While it might _appear_ that we can look at an event as say that the person was not paying attention, the truth is that when we reconstruct an event we are viewing it through hindsight and in doing so we can see a clear path from the outcome back to the actions. The path is much less clear when you look at it from the other way.
Not necessarily not paying attention. There are many errors that can be identified, whether through physical evidence, CVR/ATC recording, etc, from the pilot-forward point of view. Errors of misplaced priorities due to distraction(s), not doing the correct actions at the correct times, failing to fly the aircraft first and ending up hitting the ground, something attached to it or another aircraft when not intended. Etc, etc. There are many conclusions that can come from many different kinds of human actions and inactions, that learning can (and always should) be derived from in a FAR deeper manner than just "pay more attention".
At-risk is a condition where a person intentionally deviates from a procedure but for a good reason. We are not supposed to look at the outcome in this, but the fact is that when a person deviates as a normal course of business at it works out well we say "that person used good judgment", but when it turns out badly we castigate them. In the algorithm we look at this as an organizational issue, and if done right, we say that the procedure or policy is out of sync with reality and that needs to be fixed.
Again, there is alot of learning that can come from situations like these when it comes to figuring out whether so-called "best practices" are actually that, or are they really not. You have to peel back the proverbial onion in these cases and see why a pilot was doing a particular action. Was is the course of normal business, or was it an procedural deviation during an emergency, that ultimately went bad due to other contributory factors?
Here's an example of an accident that falls under this, and alot of procedural learning came from this one with regards to best practices and related risk factors, for dealing with a dead stick aircraft. Decisions were made with the best intentions during an inflight emergency, but a combination of secondary factors came into play to make what would've been a deviation on this particular day far more risky than had it been a CAVU day. That may not have been immediately apparent at the time, and the chosen course of action could not be reversed once it was committed to unfortunately. Nothing to castigate the pilot over, but things for the community of pilots who flew that same plane and similar ones, to seriously consider and figure out what they'll put into their bag of tricks if faced with a similar situation. As well as potenital for new procedural guidance to be generated if determined to be needed.

The third is reckless, and that is just those rare times someone just does something that they know to be wrong. That is outside of this discussion (although there is evidence that pilots of RPV's are more inclined towards this as they do not have personal "skin in the game").
And there are accidents of this type too, such as the Delta Air Lines pilot who decided to perform a loop over his family's farm in Texas in his F-16 while XC, and packed it into the farmhouse, morting himself.
RPV pilots actually do have skin in the game, in that, while they may not be onboard their aircraft, they are directly responsible for what their remotely piloted aircraft does, barring some technical situation completely beyond their control. So they may not have "physical" skin in the game, but they certainly have "liability" skin in the game. So for normal operations, if an RPV has an accident.....midair with a manned aircraft or impacts the ground and kills people on the ground, the pilot is just as responsible as if he'd been onboard the aircraft itself. In that respect, that would be their skin in the game. Same skin, just different location.
So, with that definition of "error", just saying someone made a mistake does little to help us, but that is precisely what we do with tools such as HFACS.
That's not what I advocate. As explained in my first post, that "error" term is merely a
causal descriptor. Without expanding upon that and answering the many questions I posted that delve deeply into that error and defining what that error specifically was, then it's nothing more than just that: a
descriptor. As I said, you won't find an accident where the probable cause is "pilot error. That is all. Case closed"; without there being any kind of expansion, investigation, analysis and discussion as to what that error was; so it can be understood to the best ability possible, and lessons derived from that disseminated as necessary.
