==Remember 50% of the population is below average in
intelligence [and almost all other factors]==. I am still
looking for a study showing the median/average and 1st
decile [cutoff] IQ distribution for these "high-tech" and
other positions, so I can compare to the known adult
population IQ distribution. There are of course categories
within the aggregate IQ score which may be more significant
than aggregate IQ such as spatial
discrimination/visualization.

This is old problem for the military. I went through an electronic
school with a very high failure rate. AFAIK they used it to sort
recruits by skill level and sent the dropouts to appropriate other
classes.
