A claim that face categories have obvious boundaries has become the topic of our next discussion. 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 <a href=https://faceshapecalculator.top>face shape calculator</a> for the vocabulary involved. I would introduce it as an example to discuss, without claiming that its labels settle the argument. Using one unchanged example would keep camera angle differences out of this particular discussion. What would count as a fair counterexample to the claim that these boundaries are always clear? I want the discussion to leave room for useful descriptions as well as honest uncertainty. Participants should explain which visible features support their interpretation.
