It could be. What I did, in my experiment, was used the Johnstone responses of "Yes ands" and "yes buts" to create the rough outline of the setting. Details I later filled in myself, to create a more cohesive and sensible setting. Obviously Johnstoning is going to create an inherent mishmash of ideas--this is not the final copy. The final copy should be completed by the Johnstone Initiator (or JI), aka the GM whose building the setting.
For instance, here's a brief rundown of what we knew:
There were three countries.
One was facist, two were part of a democratic alliance.
The facist one was human-supremacists. The other two were ostensibly not, but one of them (the more economically powerful one) had a lower class that was filled with human-supremacists.
We gave the countries names, and I then wrote out the details: The human supremacists were part of a theocratic facism. The human supremacists in the other country were moles an were supported by the facist nation. The other nation was primarily made up of non-human races.
Suddenly, what were just a few disconnected ideas became a whole story. You're only going to get a rough draft for the setting from Johnstoning, so it's going to require some fine tuning either just by yourself or by a collection of hand-picked individuals.
