In the online issue of the Scientific American, Gareth Cook asked Susan Cain (author of Quiet:The Power of Introverts in a World That Can’t Stop Talking if there was any connection between introversion and creativity. Susans reply was this;
Yes. An interesting line of research by the psychologists Mihaly Csikszentmihalyi and Gregory Feist suggests that the most creative people in many fields are usually introverts. This is probably because introverts are comfortable spending time alone, and solitude is a crucial (and underrated) ingredient for creativity.
The creative process for an introvert can begin long before they put their pen to paper, their fingers on the piano keys or their brush on the canvas. Creativity is born of inspiration, reflection, and then execution. And repeat. Even when a piece is created, it can be dumped completely or changed as continual reflection takes place.
The creative process for an introvert is a thoughtful, constant and solitary adventure.
