There are very significant cultural differences between these different groups. A person’s way of thinking is taught almost exclusively by family culture and community culture, not school. There are major differences between white, black, Hispanic, and Asian culture.
Most whites have a multigenerational American or European background. In these cultures technical prowess dominates. These are not primarily labor focused cultures. An office job is the standard job people are culturally expected to achieve. Many shoot for a higher paying management or corporate job. Obviously the brain is most important in this culture.
Many Hispanics have migrated to the United States in the last 3 generations. In their country of origin most were used to labor as the primary source of income. Physical work is the cultural expectation. High mental performance is sadly not as culturally important. That doesn’t change when these people come to the States. The labor disposition is inevitably passed onto their children.
Asians have come from a culture where a higher education is extremely essential. They are culturally expected to excel in school to ensure a good standard of living later. This doesn’t change when they come to the States.
Blacks are a story of their own but in the end, physical strength and ability has been more important to the culture than education.
There are absolute exceptions. Many live down their potential and many go further than what is expected of them. I’m only speaking in general percentages, as is the author of the article.
As a whole, the difference between the percentages in gifted and talented sections of school come from the cultural expectation to work hard and the cultural expectation not to. How someone fights that, I’m not sure. I’m not even sure we should. But while racism is still so prevalent (and inevitably a part of these percentages) let’s fight that first. We should worry about conquering that before trying to erase our cultures.
I’ll say it again. Culture might define mass percentages. But it doesn’t have to define individuals.
