It's like when homo sapiens came to Europe and Asia and found these people neaderthal in Europe and mid east and denisovan in Asia. They were like modern aborigines today basically.
They inherited our brains thru intermarriage but their still some left over junk from neaderthal and denisovan periods their no quick at anything but memorising and I assume they did the same during homo sapien Era untill another wave of E1b1b men laid down farming and settlements in the Levant and north Africa.
They can't just breaks things down into random groups and sub groups on any topics look at relationships involved, they set there and look at details details details

I've seen how they think at school, I just didn't know it was neaderthal and denisovan gene, for that I was ignorant.
Anything complex is always broke down into groups and sub groups and then you look at relationship happening in different stages and how it combines or merges to a final outcome, basically a tree with branches and leaves thinking.
I avoid them like the plague cause you got like 100 years in life and no time for their granual details memorisation like idolatry but I don't blame em their no different to their neadethal and denisovan ancestors.
