Sixes are preoccupied with worst-case scenarios. They stew over who can be trusted, whether the boss is on the level, and what could possibly go wrong. The pugnacious, counter-phobic version actively confronts these concerns. Others may be frustrated by Sixes' over-preparedness, procrastination and paranoia. At their best, Sixes can be original thinkers, imaginative, faithful, sensitive, intuitive, committed and ultimately courageous partisans, especially in defense of the underdog; they are terrific at ferreting out hidden motives and pitfalls along the way.
