I looked through it. I think there are many issues.

Issue 1: It says that a white American mixing with a Asian American results in higher IQ than average white IQ and average Asian IQ. That makes zero sense.

Filipino has average IQ of 103.53. White has average IQ of 100. But White & Filipino has average IQ of 105.07. For White & Asian Indian, it is the same thing. White & Asian Indian has average IQ of 109.62. Asian Indian is only 102.42. Huh?

Issue 2: How does Central & South American have an IQ of 94.7 when White Cuban have an IQ of 91.78? Don't Central & South Americans have less European genetics and more Amerindian genetics than White Cubans?

Issue 3: Shouldn't Indian-Americans have the highest IQ? Their median household income is the highest compared to other ethnic groups. Higher IQ means higher income. https://en.wikipedia.org/wiki/List_of_ethnic_groups_in_the_United_States_by_household_income

Is there a better source? What do others think?

On issue 2, you dismiss the known social factors, and insist genetics should be responsible, then on issue 3, you want to appeal solely to a social factor again. This is complex and multifactorial. Even something as small as fluoride exposure can statistically affect IQ. What is the average age of the mothers in these groups, does it differ? That matters too, older mothers have children with lower IQs. Furthermore, what are the traits of the people most likely to immigrate? If Indian, they are likely to be highly educated to be able to get Visas here, even though the average IQ in India is quite low. If south american, they are likely uneducated. You would need to control for a whole lot more variables to make the kind of statistical inferences you want. There could be many many reasons that could account for the data you are looking at

Higher IQ means higher income.

Thats not how statistics work, higher IQ implies higher income all other things being equal, i.e. it only means that when ALL the other contributing factors are exactly the same, and we have no idea if that is the case from the data you have listed

I'm sure that those numbers are as accurate as the election was accurate in 2020

For Issue #1, don't dismiss out of hand that it could actually be true. Hybrid vigor is a thing.

But it's also a small sample size and there could be all sorts of social effects going on. For instance maybe most Asian Indians stick to their own kind, but those in high status professions are likely to marry someone else in that profession instead. So it could be that half-Indians are statistically likely to have two doctors for parents. Just the first plausible sounding example that came to mind, but you know, something like that.
