It’s possible it’s for other reasons, though. Black Americans are generally poorer than other Americans, and success in sports is a ticket out of poverty that is accessible to people in that position. It could also be a cultural thing; I doubt Finns are genetically predisposed to be exceptional drivers, but they are still wildly over-represented at the top level of motorsports for such a small population
If you have fact-checked it, why not just say that wherever you did that is where you got the answer from? People are right to be skeptical of “ChatGPT says so”, and if you’ve used it as the start of your research rather than as your entire research then just saying “I asked ChatGPT” is no different to “I googled it”, and nobody would much like you saying that either. How you found the information is less important than where you found it.
