Found a great, lengthy & detailed article detailing some personality traits common to creative people. Excerpts below (the article is well-organized, which is hard to tell from the few snippets I’ve included here).
Perhaps the most difficult thing for creative individuals to bear is the sense of loss and emptiness they experience when, for some reason, they cannot work. This is especially painful when a person feels his or her creativity drying out. Yet when a person is working in the area of his of her expertise, worries and cares fall away, replaced by a sense of bliss.
Artist Eva Zeizel: “This idea to create something is not my aim. To be different is a negative motive, and no creative thought or created thing grows out of a negative impulse. A negative impulse is always frustrating. And to be different means ‘not like this’ and ‘not like that.’ And the ‘not like’–that’s why postmodernism, with the prefix of ‘post,’ couldn’t work. No negative impulse can work, can produce any happy creation. Only a positive one.”
Creative people, to an extent, escape rigid gender role stereotyping. When tests of masculinity/femininity are given to young people, over and over one finds that creative and talented girls are more dominant and tough than other girls, and creative boys are more sensitive and less aggressive than their male peers. […] Psychological androgyny refers to a person’s ability to be at the same time aggressive and nurturant, sensitive and rigid, dominant and submissive, regardless of gender. A psychologically androgynous person in effect doubles his or her repertoire of responses. Creative individuals are more likely to have not only the strengths of their own gender but those of the other one, too.
People who bring about an acceptable novelty in a domain seem able to use well two opposite ways of thinking: the convergent and the divergent. Convergent thinking is measured by IQ tests, and it involves solving well-defined, rational problems that have one correct answer. Divergent thinking leads to no agreed-upon solution. It involves fluency, or the ability to generate a great quantity of ideas; flexibility, or the ability to switch from one perspective to another; and originality in picking unusual associations of ideas. … Divergent thinking is not much use without the ability to tell a good idea from a bad one, and this selectivity involves convergent thinking.
