1. Genes. Some people just have better DNA than others. Halle Berry was born to be one of the most fantastic looking women in history; Chelsea Clinton was not. No amount of dirt or bad clothes could make Ms Berry unattractive. No amount of makeup or Armani could make Chelsea otherwise. Some athletes die of a heart attack at 35. Some chronic smokers live to be 100. Diet. DNA is a blueprint, not a finished building. You could take the best work the Ghost of Frank Lloyd Wright could draft and build it with Soviet era cement and New Jersey mob labor. The finished building might look like the elevation but it wouldn't be safe and it wouldn't last. People who smoke and drink sometimes become centenarians, overweight people never, ever do. Diet starts in the womb. A lack of a single vitamin as a child makes you a disfigured cripple or blind or dead. 2. Nurture. I honestly think most kids, even those who get the short end of the genes, are born to be geniuses. The problem is, it's really a trivial task to make a child stupid. Children are sponges, they absorb whatever is around them. All it takes to make a child stupid is to soak him or her in irrationality. You would consider someone evil, and probably criminal, for raising his children to believe they were ruled by Martian overlords who reward faithful service with eternal life through their ultra-science and are one day soon coming to claim the Earth though they haven't been seen in person for many hundreds of years and never left any evidence of their visits. You would expect the children to be idiots, incapable of understanding reality; unable to know what constitutes logic and proof or even justice and reason.
Because 90% of people has a low IQ, and this fact makes many people appear more intelligent, but the really intelligent people is just 1% of the population. There are stronger, healthier,smarter people, and there are differences of all sort among people.
Some people study more than others, have the resources to develop their brains and genetics. Your parents may not be smart, but still your child could be smart if they practiced studying to develop their brains from a young age.
