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. We could discuss a borderline outline and ask which observations support each possible description. 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. The reference would provide a starting point, while the reasoning would still need to be explained. 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? Ideally, we would finish with clearer language for describing uncertainty rather than another rigid rule. Participants should explain which visible features support their interpretation.
