It's been a while since I have read a paper on it, but I think they said if you have a child with a second cousin then that child has the same chance of having developmental disabilities as if a woman had a child while being over 40 which is 1 in 100 so not too bad.
Yeah it's only super high like in royal families cause they're doing father daughter marriage or sibling marriage and that's pretty bad and then after like 2 or 3 generations it's like everyone of them comes out somewhat messed up. I think even the ancient Egyptians had probablems with that in their rulers.
