Commentary addresses vagueness in psychological concepts, highlighting the need for clarity and definition.
Hutmacher and Franz (2025) argue that psychological concepts are inherently vague and prescribe to embrace vagueness. Ironically, despite the argument that embracing inherent vagueness of concepts entails concept clarification and discussing definitions, Hutmacher and Franz do neither with their own focal concept. This allows them to engage in a motte-and-bailey fallacy through the equivocal meaning of concepts such as "feature," "bug," "embrace," and "vagueness" and in turn to overstate their conclusion that vagueness is a feature to be embraced.
