I agree that the latter two examples have Moorean vibes, but I don’t think they strictly speaking can be classified as such (especially the last one). (Perhaps you are not saying this?) They could just be understood as instances of modus tollens, where the irrationality is not that they recognize that their belief has a non-epistemic generator, but rather that they have an absurdly high credence in ¬Q, i.e. “my parents wouldn’t be wrong” and “philosophers could/should not be out of jobs”.
