For our next discussion, I chose the idea that every facial outline has one unambiguous label. The difficulty for me is explaining where one category ends when proportions vary by small amounts. I would like to compare the reasoning behind two labels applied to the same borderline example. The group could describe the visible proportions first and leave the category until the end. One possible starting reference is face shape calculator for the vocabulary involved. It would serve as a discussion prompt rather than evidence that a particular category must be correct. Using one unchanged example would keep camera angle differences out of this particular discussion. How would you demonstrate an uncertain boundary without simply dismissing the usefulness of categories? The goal is a careful argument that recognizes both practical shorthand and its limits. Participants should explain which visible features support their interpretation.
