There are two Reading People types that can spark the greatest interpersonal conflict and that is Mars and Mercury. Mars is the classic law enforcer, dogged and determined in their pursuit of wrongdoers and can be rigid in applying the rules. Mercury types are flexible and adaptive, they often believe the rules are designed for the slower thinking types and they themselves are somehow exempt.
In movies we typically see the “good honest guy” played by a Mars type and the archetypal stage villain played by a Mercurial type. Terminator 2 is a text book example of this dynamic. Oscar Pistorius is a Mercury and the prosecutor in his murder trail Gerrie Nel is a Mars who is known for his confrontational style. We can expect some serious fireworks during the cross examination.
