“Geniuses are those who have the intelligence, enthusiasm, and endurance to acquire the needed expertise in a broadly valued domain of achievement and who then make contributions to that field that are considered by peers to be both original and highly exemplary.”
― Dean Keith Simonton

“Even worse, those with accomplishments worthy of the designation
"genius" do not always make the IQ cut. When Terman first used the IQ test to select a sample of child geniuses, he unknowingly excluded a special child whose IQ did not make the grade. Yet a few decades later that overlooked talent received the Nobel Prize in physics: William Shockley, the cocreator of the transistor. Ironically, not one of the more than 1,500 children who qualified according to his IQ criterion received so high an honor as adults. Clearly, a Nobel laureate has much greater claim to the term genius than those whose achievements did not win them such applause.”
