Not every belief is about truth. You may hold X to be useful because it’s useful, and Y to be true because it’s true. The mistake is to automatically hold X to be true as well, or Y to be useful. Restating that as “X being useful is true” erases the distinction or invites unnecessary rigor. In the same vein, there are judgements of falsehood or necessity or need, and these are about falsehood or necessity or need and not about truth.
