Si connects with resistance to change because it manifests as a disbelief in the expectation of differences. Si builds impressions based on experience and then interacts with things primarily through those impressions. An oversimplified example: an Si user sees its first cardboard box and learns that cardboard boxes are brown. When that Si user sees a cardboard box that's a different color, there is a question of whether this is a cardboard box at all, and a preference (if given the choice) for the familiar brown type of cardboard box. Over time, this changes. The older an Si user gets, the broader their base of experience. I theorize that ideally there is a breaking point where Si goes, "oh, I get it... boxes can look very different from each other, but are still boxes." This is a point where the Si user does not need to see new kinds of boxes to accept them.
