Yes I have used this study but it was aimed at looking at the difficulties you might face entering into foreign markets. I used the words “More than Likely” as it is difficult to give absolutes.
I will say that this has brought out your prejudice and bias quite nicely.
It also show how you have failed to comprehend the information.
Try this
The study is like google, the accuracy of your search will be determined by the parameters that you input. So if you say south Africa it will give you a large result which will not really answer your question. In order to answer your question you will need to add parameters to refine the answers
So lets say Sex, Race, Age, Geographic location etc This will give you a better answer
The scale shown on their website is from a broad search and the answer will be skewed as the sub components will change the answer. Therefore you have to refine it.
As for the aspects I mention been unique to African culture of course they aren’t, they can been found in all cultures at various points in their development. I would hate to see what the tool would show if applied to ancient Rome.
Good or Bad these aspects do exist and need to be dealt with
