Does IQ Matter, do you believe in racial IQ?

Stumbled apon some interesting studies showing that IQs can be averaged based on your race. Such as, currently.

Jews:114

Eastern Asian: 108

Western European White: 104 (Germanic Peoples scored 105)

Western Asian: 104

American White: 102

Eastern European White: 101

Native American: 99

Latin American: 96

American Black: 93

African Black: 85

These have moved signifigantly in some places since the 1700s with the gap getting smaller as globalism causes races to interact and mix, with exception of jews that have risen 4 points. So my Question is this, based on this data would it be appropriate to say some people are more capable of doing certain tasks then others, or do you think IQ is not an important indicator of proficiency or productivity? Do you think this study is racist or factual? Btw have you taken an IQ test before? A certified one not a Facebook test or some free one off the internet. I personally think they should be mandatory in education. I got tested twice once when I was thirteen and another time last year. I'll post my results if you want.
