Do you have a "family history" of aviation/piloting? No
Are you an adventure seeker (anything from "true" adrenaline junkee to
"every day is different and brings a new challenge") No
Are you constantly seeking new challenges? somewhat
(subpart) Do you find that you get bored easily? No
Do you have a "thirst for knowledge" (e.g. would you rather be in
school than working)? No, though work is a learning experience for me and I intentionally went back to work after retiring.
(subpart) Do you find yourself constantly seeking out new things
about flying regularly or do you only look it up when you run across
something you don't know. Yes
(subpart - for instructors) Do you enjoy it when your student "gets
it" or has that "aha! moment?"
Are you a "control freak" (type-a)? no
Do you have hints of "delusions of grandeur?" or is it more like "I'm
on top of the world when I fly" no
Are you an introvert or an extrovert? intro
If given the choice, would you rather read fiction or an aviation
oriented book? yes
(For those that use the radio) Do you find that you have always had
good communication skills? yes
Are you left brained or right brained (logic-and-math or Artsy
fartsy)? yes

Or am I missing something soooo obvious that I'll die of embarassment
when it's pointed out to me? Or even worse, is there no measurable
psychological correlation to flying and I'm just out to lunch
(wouldn't be the first time g)

Note:
I was thinking about including education history (e.g. are pilots more
likely to be college graduates) but that introduces 2 biases (age and
income) into it. However maybe a question along the lines of "while
in school did you consider yourself to be a good student" would be
better. mediocre student until I got to grad school, then excellent

I've asked myself why I spend all this money and time (and sometimes,
anxiety). My wife would tell you that flying restores my soul in some
way. There is some utility value to go places, but that isn't the
primary driver.

There's something magical about being suspended between heaven and
earth that can't be duplicated in any other way. Sometimes commercial
flight is good too, but less and less often anymore.
