The pattern from the small sample in the poll so far seems to be that most respondants are N's - Intuitive as opposed to Sensory.
From Wikipedia:
"Sensing and Intuition are the perceiving functions. Jung called them the irrational functions (as a technical term, not as a pejorative), as a person does not necessarily have control over receiving data, but only how to process it once they have it. Sensing people tend to focus on the present and on concrete information gained from their senses. Sensing prefers to receive data primarily from the five senses. Intuitives tend to focus on the future, with a view toward patterns and possibilities. These people prefer to receive data from the subconscious, or seeing relationships via insights."
Maybe the FSP should focus their advertising on audiences and professions that favor this trait. Just a thought.
