false positive, false negative

  • beware: in diagnosis and diagnosing, there is the pitfall of false positive (determining and evaluating a thing to be true [positive], when it is false), and, false negative (determining and evauluating a thing to NOT be true [negative], when in fact for that period in the timeline, it is true), not accounting for the final and true cost in time, opportunity, and resources for the evaluation; there could be multiple aspects to a singular problem or situation; making things complicated, because an aspect to this situation [the environment, and, this period in time] could be true [1], another and different aspect to the same situation could be NOT true (false) [0]; and a third aspect could be in the grey zone [fuzzy - neither 1 nor 0]; 

 • false positive (determining and evaluating a thing to be true [positive], when it is false)
 • false negative (determining and evauluating a thing to NOT be true [negative], when in fact for that period in the timeline, it is true)
