As a student at the University of Chicago I studied with Dr. Benjamin Bloom. We were interested in the development of talent. We studied scientist, mathematicians, swimmers, tennis players, artists, musicians. We were trying to see what the commonalities were in people who went on to set world records. The findings were very interesting and very important and very relevant for us in all walks of life. The most important thing turns out to be the early family environment. The supportive role that families play. The supportive told that teacher and coaches play. The importance of putting pressure on those kids and the interplay between the kids and the teachers, asking for more work. The upshot of the study was that genes don't make a great deal of difference, the important thing is early training and family environment.
