Why have we not had more female writers, painters, scientists, sculptors, or artists. One explanation offered is that many women do not perceive themselves as creators, follow their interests into career preparation, or place importance on the works they produce. Moreover, the problem may be further exacerbated even when a women produces an original, creative work of art, as some researchers have found that women are more conscious of criticism and find it more difficult to deal with negative perceptions of their work.
