the gap between research and practice is particularly wide for racial and ethnic minorities.
This is very revealing in regards to why racial disparities in the United States remain untreated despite there being "research" occasionally being conducted. When the government does studies into racial minorities, they don't always do anything with this information, making these researches pointless. They can say that they've done research into these issues to appease the public, but they continue to neglect said problems and the systems which put minorities down remain unchanged.
