This poll was never going to be "hyper accurate" and that was never my goal anyway.....
The options provided are vague definitions that allow somebody to contextualise their security knowledge against other members.It is not a checklist.
I am polling members opinions of their own knowledge,based on the given criteria.
Everything is subjective...from a very early age most of our opinions (whether they be about ourselves or others) are influenced by personal opinions/tastes/preferences/desires/inherent emotional weaknesses/prejudices /experience/intuition....
Would you hold back from offering an opinion of good AVs or Security practices for example? ....as those opinions are not "Absolute" or "Guaranteed" either!
Human Error (To answer your question)..can be categorized by IQ x Relevant Experience x Attention Span x Fatigue Level x Competing thought processes.............But I figured that may be too complicated to include in the poll
