I’m not surprised by the male bias in hiring algorithms for a couple of reasons.

One, the algorithms are created primarily by white male designers. So without deliberate inclusion at the design level, of course it’s going to be skewed.

2ndly, Amazon favors speed in the performance metrics over consistency, accuracy, or thoroughness (by this I mean not creating problems in the production pipe) in subtle ways that lead to male bias.

For example, the constant speed competitions. They favor young men hands down. During the holiday season and prime week young men walk out with some pretty hefty prizes.

Young men tend to not last long there. These competitions are a big reason why. Whatever rate you make, you’re encouraged to keep making forever. There are subtle penalties if you don’t. You get labeled as lazy. You don’t get opportunities to branch out. You get “encouraged” to make that rate that was so awesome. Again and again and again. Even if you’re working a different area where it’s just not possible. (Pallet land vs. library).

They want you to sprint yourself to injury in a marathon race.

Young men tend to get frustrated and quit a lot sooner than their female counterparts who pace themselves better.

There are other quirks leading to male bias too, but that’s an example.

Ultimately, this means they probably hire a lot more males than females because of the disproportionate number who just can’t keep doing it. At least at that level.
