Keirsey also noted that Rationals, unlike other temperaments, aren’t so much given to lectures, scoldings, and groundings so much as simply stating, “Okay then. You’ve lost that privilege for awhile,” and then depriving the child of the opportunity to affect/enjoy/control that part of their environment. By such impersonal, logic-based and minimally punitive measures they teach their children that bad behavior isn’t about “me being angry at you and trying to make you feel bad to show you the error of your ways” so much as “you making an illogical choice that results in the loss of your pleasure.” The idea is to teach the child that poor choices always imply logical negative consequences. The Rational parent tries to demonstrate that making a bad choice is like throwing a rock up in the air and letting it fall down and hit oneself in the face. It isn’t that the rock hates you, or thinks you have done wrong; no, the rock has neither feelings nor any sense of justice. Rather, the rock is merely obeying the amoral, implacable laws of physics. Many people break rules, but few people try to break the laws of physics. The logic-oriented Rationals instinctively realize this, and tend to have better success with discipline than other types.
“The night I was cast, I went out and bought The Empire Strikes Back and Jaws. My goals were to get a voice as sinister as Darth Vader and the menacing physicality of the shark. It’s so easy to take these big beasts – these ferocious characters – and cook them at ten the whole time. But I wanted to have this circling, steady presence that would suddenly attack randomly. Peter allowed me to make a lot of adjustments. Being a Maori, in the scene where I’m beating up Thorin, I rocked back on my warg, raised my eyes up and did this look that in the Maori world is called ‘pukana’. You show the enemy the whites of your eyes. It just happened instinctively and at the end of the take I said, “Peter, I think I pukana-ed!” I didn’t think he’d use it, but sure enough, when I went down to the premiere with a bunch of Maori friends, there it was.”
