Because humans haven't been selectively bred for specific traits.

Because dog breeds are not comparable to genetic differences in humans. They've been actively bred for certain characteristics, going through a lot of generations extremely fast in controlled environments in a way that's impossible in nature. All humans are essentially mongrels. The reason we don't do racial classification of personality traits in humans isn't just because it's morally abhorrent, but also because it doesn't work, while because of the selective breeding of dogs, there can be big differences in their behaviour due to their breed.

It's also important that while a dog's breed does have an influence on it's behaviour, it's not absolute, and you can't actually predict a dog's behaviour through its breed alone.

Drawing on a study produced by the Becker Friedman Institute for Economics at the University of Chicago, Pagaduan reported that 53 percent of the sheltered unhoused population and 40 percent of the unsheltered unhoused population were employed either part- or full-time from 2011 to 2018.

Literally the second sentence of the article.

That's sounds pretty promising. How does it actually function? I'm asuming it can't be hormonal considering how hard it is to block sperm production that way, which could maybe mean less (or at least different) side effects than hormonal birth-control.
