Gifted and talented children are born not made, according to a 45-year study of gifted children.
Some gifted and talented children are so intellectually gifted that it is impossible to measure their IQ.
Many are society leaders.
An example is Joseph Bates a gifted and talented mathematician. At age twelve he was so far ahead of his classmates in mathematics. To encourage him, his parents enrolled him in a computer-science course at John Hopkins University. He was brighter than the students in his university class.
