For example, there is a fairly widespread / rampant "cheating/copying/don't-bother-learning" culture in a lot of schools in India, especially as it relates to software development. I've seen it brought up and stated as truth by people from that region over and over. There are also many VERY smart, skilled, devoted software developers from that are. I've worked with quite a few. However, because there _is_ that culture, the "noise" (bad developers) to signal (good developers) ratio is really high. And, when dealing with developers from that area (especially, from my experience, those at various contract/churn companies), you need to be careful about the work they're doing. You need to check to see it's being done well ... at least until you're familiar enough with the people/team that you can trust them.

Culture _has_ an impact; but that doesn't mean it should be assumed... just that it may mean you need to pay more attention.

The cost to black women to get their hair done is generally more than any other group.

Almost all black women (and probably black men) have had to develop some coping mechanism for the number of non-black people who want (or at times, demand) to touch their hair.

Digression-- I remember a black doctor who had a coping mechanism for the number of patients who assumed he was the nurse and asked him where the doctor was. He would spin 360-degrees and then present himself to the patient again. :)

As for the sibling comment-- my first three sentences are falsifiable.

Edit: clarification

tl;dr: Sowell contends that the "black ghetto culture", characterized by violence, a lack of ambition, a dismissive attitude toward education, and a casual approach to work, is not inherent to African-Americans. Instead, he argues that it is a cultural relic of white southern 'Redneck' or 'Cracker' culture, which was brought to the South by immigrants from the more lawless regions of Britain.

These immigrants, according to Sowell, came from areas that were marked by a resistance to work, a lack of education, a predilection for violence, and a general disregard for the law. These cultural traits, Sowell argues, were absorbed by the African-American population in the South during the era of slavery and have been perpetuated in certain communities to this day.
