I often wondered why Indian students academically excel, especially in the field of physics. You will find that cultural factors are predominating. For example the demographic that I live in is multi-cultural however a visit to the local library shows predominately Chinese and Indian parents with their kids reading books. I believe this cultural focus on academics prepares Indians for high academic achievement. Now I rarely find Melanesian and Polynesian kids in the library and you will find that these groups do not score as high in The University Admission Index (UAI) but I don’t think the answer is that their less intelligent, simply there is less focus on academics.
In terms of sport the average Indian does not have a cultural focus sports in general. If we look at eye hand co-ordination sports, Indians are gifted in these sports eg cricket & golf, they excel in power sports Olympic lifting.
