The brain chemical reward system, defines for each individual what is boring and what is not so gaining knowledge for the more intelligent is neither dull not boring but quite a soothing pleasant mellow ride and interruption of said mental ride can and often will result in quite negative expressed reactions. This in it's most extreme form is represented in autism, where singular mind focus disrupts from normal social development and disruption results in reaction akin to drug addicts being denied their substance of choice. The brain chemical reward system is somewhat flexible and can learn new stimulants to provoke that reward but again that varies between individuals.
To confuse issues of course, you can have a genetically more efficient and effective mind however due to lack of brain chemical reward it is not exercised and you can have a less efficient and effective mind but the brain chemical reward not matter how used really does not achieve all that much, in comparison to others.
So likely a composite of factors including diet of the mother during pregnancy as well as health and well being during childhood. Not just genetics, let alone a single genetic trait.
