People with low IQs aren't more likely to get an abortion by their own volition; desperate people are. That means younger people who made a mistake (condom broke, birth control fucked up etc), people of lower income (more related to environment than IQ) or cases where the pregnancy might cause harm to the mother. IQ literally has nothing to do with you're likeliness to get an abortion. With that out of the way, it is a fact however that increasing access to birth control, abortions and other family planning methods is better for society. Not because were somehow bettering the gene pool, but because when unwanted children are no longer being born, we reduce crime rates. Unwanted children typically face neglect be it by the foster system or their birth parents, access to only lower quality education and just bad parenting in general, a cocktail that's almost always guaranteed to hinder future success. So yeah, abortions are good for society, but not in some weird eugenicist way you freak
