Constructiveness is a faculty from the discredited pseudoscience discipline of phrenology. Constructiveness is the seat of initiative, creativity and originality. It confers the capacity to plan and construct, to design and invent, to organise and devise ways and means of carrying out projects with ingenuity and dexterity. It is localized on the temples, below ideality.
