The Hunger Games, Suzanne Collins
Te: Gale doesn’t like to sit by and do nothing when there are things to be done. At times, Katniss finds his rants and plans for changing district 12 annoying and unrealistic (but only because she’s Si-hesitant to act before all the details are worked out). Gale is a strategic thinker even in the starkest situations and when Katniss is leaving for the Games, he’s the one who’s able to talk a strategy into her head (he doesn’t try to comfort her; he tries to give her a set of instructions that will keep her alive). Gale’s decisions are objective and though his personal feelings run deeply, he doesn’t allow them to influence his choices.
Ni: One of the first pictures we get of Gale is his raging idealism (which Katniss finds annoying). He sees the world in terms of the big-picture and hates to be stuck doing anything that feels insignificant. His mind is long-term oriented, and as a result, he often gets disillusioned with the present. Gale is good at advising Katniss where she fails to see the future consequences of her somewhat impulsive nature. He understands Katniss a lot better than she understands herself.
Se: Gale knows how to improvise and use his environment to stay alive (first as a hunter, then later, in paying attention to his surroundings in order to avoid stepping on land mines). Occasionally, he can be impulsive, but only when his ideals are threatened (NiSe). He seems to be fearless in dangerous situations and loves to be at the thick of the action. hunting skills are excellent, and he has an opportunistic streak.
Fi: Gale has strong feelings about nearly everything –anger towards the capital, love for Katniss etc. Yet, he doesn’t often voice his innermost emotions and motivations until forced to do so. His sense of morality is black and white, and he doesn’t let his emotions affect his decisions. He doesn’t care what other people think of him, which only further serves his objectivity.
