I have been working on the "People need X in order to Y, UNLESS People need A in order to B" technique to better understand the inequities in my story (as elaborated by Jim in his recent articles, and writers room, and as discussed recently on this forum).
My OS is in Activity, so I first did one for that.
Then I tried to do one for Understanding, as that is my first OS signpost, but it proved to be more difficult.
Then I noticed something interesting..
For the Activity justifications, X was kind of related to learning, Y to understanding, A to doing and B to obtaining.
So I tried using the components of Understanding as prompts..
And sure enough, I was able to easily build the Understanding justifications, where X was kind of related to conditioning, Y to instinct, A to senses, and B to interpretation.
I don't want to share what I came up with, as it will give away the idea of my story! but I wanted to share the technique in case other people find it helpful.
I know in Jim's writers room, people have looked at the gists of the relevant story point to help generate ideas, so this is maybe another technique to supplement that.
