Has anyone read this? Pretty interesting stuff, a friend found the first article and mentioned it to me, and it lead me to the underlying one.

Like this quote from the first -
Lewis Terman, the inventor of the Stanford-Binet IQ test, came to a similar conclusion. He spent decades following a large sample of �gifted� students, searching for evidence that his measurement of intelligence was linked to real world success. While the most accomplished men did have slightly higher scores, Terman also found that other traits, such as �perseverance,� were much more pertinent.
Terman concluded that one of the most fundamental tasks of modern psychology was to figure out why intelligence is not a more important part of achievement: �Why this is so, and what circumstances affect the fruition of human talent, are questions of such transcendent importance that they should be investigated by every method that promises the slightest reduction of our present ignorance.�
