Yah.
Get your mental polaroid camera geared up, starting walking through life, and take pictures of people with different types and categorize them. You'll see each type has a few "common expressions."
Ivy would be in one I've only ever seen in one other person I know. (She's the same infuriating IxFJ split.)
Although I'm trying to step back from Rose and see her with "new" eyes. She's so clearly ISFJ, as her base, but I'm too close to her to see who she has become because of our relationship.
As far as ducks and Geoff, well, of course that ruins everything, doesn't it?
I've snapshots of all types except the INFJ IRL - that's why I call them my blindspot. If they do not fit into the other 15, they tend to be INFJs then.
Re Geoff and ducks He avoids duck conflict and merely photographs them vs splash after them (don't even ask). Ruin is a question of perspective then.
