Compliant has Estimated and Situational
Obstinate has Estimated and Situational

Careless has Estimated and Situational
Farsighted has Estimated and Situational
and are incident-based elements ; and are foresight-based elements.

Collectivists (Beta-Delta) focus on both :
"One can't be a Consumer without being a Producer."
