Excellent discussion. Creativity is fascinating- well desired and hard to pinpoint! Usually, creativity is thought of as reserved for the arts, which of course, is a traditional if not narrow view of what creativity is. One of my favorite books on creativity is by Weisberg (cognitive psychologist).  He's done a lot of research on insight and its origins.  One of the reasons I really like his book is that he compares across disciplines for the underlying processes involved in creativity (mainly a comparison between Picasso and Watson & Crick- so art and science).  

One might argue that all research which is the foundation of discovering new information about people and the world is highly creative.  What are your thoughts on this
