I don't think people are generally creative across the board or experience helplessness across the board. The question is categorised as being about PTSD. I have known people who are brilliant and creative who've also had PTSD and been at some point reduced to a very bad state of helplessness.
I'd say if there is a link, it's more the other way around. If you have learned helplessness in an area, that will kill your creativity in that area. Without detailed studies, it's hard to know what the patterns and causalities really are though.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
