Principlev1
Seek external perspective on dimensions where you rate
Seek external perspective on dimensions where you rate yourself highly, as these are the domains where self-assessment is most likely to be inflated.
Why This Is a Principle
This follows from the Dunning-Kruger finding that incompetence correlates with inability to recognize incompetence (Systematic Overconfidence Taxonomy) and the bias blind spot (Bias Blind Spot Asymmetry). The principle prescribes a corrective action: actively seek external input precisely where you feel most confident.
