The concept of “face validity”, used in the sense of the contrast between “face validity” and “construct validity”, is conventionally understood in a way which is wrong and misleading. The wrong view had relatively limited consequences for research practice per se. However, it is a serious obstacle in theoretical discussions of certain “philosophical” or “foundational” issues. In this brief note I would like to point out the logical defect in the conventional position and correct it by making the necessary distinctions.
