Is IQ important?

The first question I need to ask now is if people really care about how smart their employees are or how high their IQs are. As it was said in the article, immigrants seem to have lower IQ than native Americans. It is hard to prove the study is wrong or right, but to give a conclusion on general generations is somehow difficult to agree with. 

We all know that intelligence or IQ is not inherited. If the parents do not have high IQs, it does not mean their kids are going to have low IQs. Furthermore, the same to the immigrants. There is no clue to say they have lower IQs then native American except giving each of them an IQ test. If it happens, what does the matter? Will we not hire someone having low IQ? 

Have a look at the immigrants nowadays, they come to the U.S for their future. Do they really have low IQs? I do not think it that way. At many developed companies, they do have immigrants working for them at higher position than the white natives. Or else, we can look at students from other nations in the U.S universities, some of them study better and even have high grades than other ones. They came to the U.S to have better conditions, better help to improve what they could not when lived back in their countries. It is very common when people reading education news or heard about some Asian, European or African students have been given scholarships from famous universities like Harvard, Yale, or Stanford. 

The important things do not come from IQs, but come from the way they adapt their new lives in the U.S, how they experience and improve themselves to make a better United States in every single category.
