I have long said that the ‘functions’ of Sensing, iNuiting, Thinking, and Feeling are not types, but are instead processes. A process is an activity that we can engage in and use. It is not the driver of who we are, but the means to help us be who we are. An important aspect of who we are is the pattern of our personality that has been there from the beginning. I often say, ‘Patterns rule processes.’ We use the processes in service of the pattern, but more on that later.
