At this point, global murder rates are more than anything racially linked. Look at a global map thereof, and you will see all majority black or Hispanic countries have a high rate, Asian and Northern European countries a low one.
Look more specifically within mixed countries such as the US, and our black and Hispanic figures mirror those of black and Hispanic-majority countries, and Asian and European, the same.
The very same correlation tends to hold for those global tests of academic proficiency.

Figure that one out and you’ll be awarded next year’s Nobel Prize in Psychology!
