Sorry I am new to this topic area but had a quick flick through and may not have done the topic justice, its just that I feel that all children/people are gifted or talented.
Take my DD, 10 months and only just learning to crawl (lazy monkey) and only doing commando style crawling BUT I am so proud that in my opinion she is so talented! She may as well be the first baby to ever crawl for how proud I am of her!!
I think that parents, friends, relatives and even schools are bias.
Who can really say whether anyone is of superior intellect or not?
At school my parents were always told that I was G&T (oh I quite fancy a gin and tonic!) but really I am very average but just went to a poor school. I was only G&T compared to the other students there. This came as a bit of a shock to me in the big wide world of work!
I am sure that there are the few exceptional cases of child genius, but I think that we all have the "right" to consider our little angels or terrors are exceptionally talented.
