Do the types of ideas generated by Ns and Ss differ, on average? I realize there's probably some overlap.
Yes, Ns are 'idea people'. But... the most prolific idea-generator I know is actually an ESTP, and he's hardly an exception among SPs I know. He is a musician and likes to draw comics, so he comes up with ideas related to those interests seemingly constantly. I would think that N ideas would be about less concrete things (less concrete than art projects, that is)...?
There are probably also differences between S and N writers... perhaps how distanced the plots/settings of the stories are from reality. Whether they are 'far-flung' or still reality-based. I'd think S writers would be more likely to make the setting in the current/past world, whereas Ns would create alternate universes and stuff?
Then there is the SP thing about action. I think that I can come up with some good ideas but I usually have the intention of acting on each of them, as I come up with them. I lack follow through, lol, but when I come up with the idea you bet I intend to act on it! OTOH, with Ns, (especially NPs): would you generate ideas without the intention of following through on them?
This also ties in to the feasibility of the ideas. You can't follow through if it's not realistic (you could try!). Perhaps it is a desire to act on the idea that stops me and maybe other SPs from coming up with impossible things :P. Maybe that means N ideas are less feasible, on average?
Ok then... I'm hoping for input from all types on this! Thanks.
