I wonder if they would have had the same results from a different study population.

Back in the days when I was a corporate tech writer, the company I worked for was into using Myers-Briggs personality inventories to understand work styles. The goal was to help us understand the people we worked with; I don't recall it being very successful at that, but it did produce vast quantities of amateur psychoanalysis of what was wrong with everything else. One of the things I remember from it is that one of the personality categories -- INTP, maybe? -- was highly prone to the kind of behavior produced in the study. The plan was as good as the accomplishment. It's a common trait of abstract thinkers -- architects and software engineers among others.

I know I'm vulnerable to this problem. Once I've outlined a story and thought it through, sometimes the life goes out of it. I've told it and it's done. But those are the weaker stories anyway. The good ones will occupy me through several drafts as I try to get it closer to what I want to say.

But related to the high-level and long term goals? I'll have to think about that.
