In the Anxiety Forum, you asked that I read your postings in this area and comment.
I am not an expert in evolutionary psychology and cannot say that I fully understand or recognize this area as a separate distinction or discipline within the "science" or practice of psychology.
The comments I can make would refer to the concept of creativity. I do believe that creativity requires channeling and focus in order for productive output to emerge. By channeling and focus, I do not mean restrictive rules or theories. I refer more to gentle, mental guidance that allows one's creativity to flow, and still relate the outcome to other relevant criteria. Unchanneled creativity generally produces a great deal of activity (flurry) without culminating in a productive outcome, idea, or product.
I have worked with several unchanneled, but very creative people. These individuals actually experienced difficulty in their jobs and life in general because they would start many ideas (things) going all at one time, and never capture credible or viable value from any of them. They also frustrated many of the people around them; specifically those individuals who looked to the creative source for their guidance and inspiration. It requires a specialized method of guidance and counseling (with practice "homework" assignments) to pull this type of individual from a creative but confusing energy mass into a more cohesive presentation of creative ideas and plans. I have found the issue of unfocused creativity to exist in both a trait and state form. This brief discussion I typically reference under the title of cognitive psychology.
Hopefully, I have provided some productive contributions and insights.
Thank you.
