Your approach to type as the characteristic way we appropriate experience and give it meaning changed my approach to teaching MBTI ® theory. Instead of saying a type uses a function, I try to convey the more difficult characteristic orientation of each type. This approach alleviates the quagmire of labeling behavior, such as watering plants, as using Sensing.
LTB: Jung didn't describe the functions as skills; he compared them to the four directions on a compass. Orientation, not innate ability. For example, you can make a reliable correlation between North and whale fishing, but orienting yourself by North won't give you the skills to work on a whale boat. Conversely, taking a job on a whale boat won't tell you how it feels to orient yourself by North.
Each function orients conscious awareness in terms of its own psychic content, just as the four directions orient us to different parts of the external landscape. To take a direction always leaves a path not taken. If you're going North, you're axiomatically not going South. Over time, favoring one orientation over another becomes habitual, assembling a consistent approach to the meaning of our experiences.
