There are many types of creativity. I've seen SJs invent things before. Isn't this a type of creativity? I mean most of the inventions are for everyday practical uses, but non-the-less they are original and they are creative. Also, ISTJs, for example, have inferior Ne, which allows them to come off with witty, whimsical jokes [a type of creativity] and also causes them to have strange little hobbies to balance out their dominant Si function. I've heard ISTJs come off with some pretty creative scenarios on aliens, space ships, etc. Hence, I've seen ISTJs who engage in drawing as a hobby. I know one ISTJ who enjoys drawing comic book characters--just for fun. My aunt, who is the ESTJ of all ESTJs, the queen of ESTJs in her STJ-ness, invents amazingly clever ways to organize things. Isn't that creativity? She comes up with ideas that never cross my mind. I know another very strong ESTJ who created an adorable bulletin board at the local elementary school where she is the counselor [she revels in blowing stereo-types out of the water]. So, I would never pigeon hole anyone into being "un-creative" just because their type of creativity falls outside my narrow definition of it.
