These things measure IQ more accurately and apply equally across cultures and levels of education.
I think your point was that test bias would flunk Lincoln out of a modern IQ test because he's not familiar with our cultural references; not that he had sub-normal intelligence. If so, I agree but your point didn't come across well. Even so, the modern testing is supposed to come closer to eliminating test bias and giving an accurate evaluation of intelligence.
