A claim that face categories have obvious boundaries has become the topic of our next discussion. What interests me is the boundary between neighboring categories rather than a list of familiar names. I would like to compare the reasoning behind two labels applied to the same borderline example. Forehead width, cheek width and jaw shape could be listed before anyone chooses a category. One possible starting reference is <a href=https://faceshapecalculator.top>face shape calculator</a> for the vocabulary involved. It would serve as a discussion prompt rather than evidence that a particular category must be correct. A single agreed image would let us focus on category boundaries rather than inconsistent photographs. How would you demonstrate an uncertain boundary without simply dismissing the usefulness of categories? I want the discussion to leave room for useful descriptions as well as honest uncertainty. Participants should explain which visible features support their interpretation.
