It is the Davidsons’ other, related aim that calls forth a different kind of fervor. Authors (with Laura Vanderkam) of a book called “Genius Denied: How to Stop Wasting Our Brightest Minds” (2004), they are on a mission to remedy what they are convinced is a widespread neglect of exceptionally talented children. That means challenging the American myth that they are weirdos or Wunderkinder best left to their own devices or made to march with the crowd. “By denying our most intelligent students an education appropriate to their abilities,” Jan Davidson warns a nation in the midst of a No Child Left Behind crusade, “we may also be denying civilization a giant leap forward.” Precocious children are not only avid learners eager for more than ordinary schools often provide, the Davidsons emphasize; they are also a precious – and imperiled – resource for the future. The Davidsons, joined by many other advocates of the gifted, maintain that it is these precocious children who, if handled right, will be the creative adults propelling the nation ahead in an ever more competitive world. As things stand, the argument goes, the highly gifted child is an endangered species in need of outspoken champions like the Davidsons, who are role models for the “supportive, advocating parent” they endorse.
