In a method for manufacturing a hearing device, by registering characteristics of an individual (I) a personality vector (K(CI)) is established in a fitting machine. The personality vector (K(CI)) of the individual (I) momentarily involved is compared with stored personality vectors (K1(C) to Kn(C)). That stored personality vector which is most similar to that of the individual (I) is selected and therefrom a personality profile (PP) which is assigned to such personality vector. There is assigned to the personality profile which accords to the most similar personality vector, a respective fitting vector which controls subsequent manufacturing of the hearing device.
