Why Taking All Four Is Better
Each framework is a single lens. Taking all four reveals consistent patterns across frameworks (which are reliable) and differences (which reveal nuance). A high I DISC profile with an introverted 16 Personalities type means you communicate warmly but recharge alone — a social introvert. That nuance is invisible to any single framework.
