You begin by pulling pieces from the outer bubbles (the further out you get from the center, the more defined the topic will be).
I could question the existence of ghosts (even though I didn't get that far with this bubble, for this exercise we will pretend it is there).
Topic #1: The existence of ghosts
Question #1: Is there scientific evidence to support my claim?
Question #2: Who are some experts in the field who I could draw information from?
Question #3: Where are some of the better known "haunted" locations?
Notice how I branched off the ghost column. I didn't incorporate any of the other branches. This will give me a good, focused topic. The fewer different directions you pick, the more focused your topic will be.
Topic #2: Aliens exist
Question #1: What really happened in Roswell, New Mexico?
Question #2: Is there scientific evidence to back my claim? If so, where can I find it?
Question #3: Are there any credible researchers with evidence to help my claim?
The same could also be done with the media branch. Maybe someone could look at the impact supernatural themes have had on the media, the audience it has found, and what that means. They could develop questions to support their research.
One could even draw a conclusion about the evolution of the hero in the 90s, and 21st century. Afterall, from this cluster we did draw out two very distinct and impactful heroes, Buffy Summers and Angel. For those of you unfamiliar with the two, they presented a distinctly new mold for the hero. Angel, the vampire turned tragic hero, and Buffy Summers, the tail kicking cheerleader from Sunnydale. Both (particularly Buffy) had a distinct impact on popular culture. And yes, there is information to support that out there.
