Dr. Amen, a Psychiatrist in Southern California has been doing gangbusters business performing SPECT image scans of patients’ brains. He helps to identify ADD, ADHD, and other conditions that sometimes define traits not to mention problem areas of behavior. He recently did a PBS special and it’s really interesting what we can learn about our own brains.
Some say that SPECT scans or other such methods will eventually become standard practice when kids enter school. Hmm….
Doesn’t it follow then that it may become a way to identify those individuals who are the best for certain positions?
Did you know that a long list of great people would be considered ADD today? President Dwight Eisenhower, Thomas Edison, Einstein, Olympic Swimmer Michael Phelps, not to mention artists like Mozart, Beethoven and (of course) Robin Williams. 
Politicians, leaders, innovators, mavericks, artists. Also bad traits like lack of follow through, poor social skills or who knows what else…
Will it become a way to screen-out those individuals who might not be the best for a particular position?
Scary stuff isn’t it!!?? Yikes!
It follows also, then that we could not just screen for big individual differences but smaller traits, abilities, and a myriad of other such individual differences.
Talent
versus Experience
versus … Brain Chemistry?
