AI is poisoned with bias against dark skin

 


Media Lab researcher Joy Buolamwini says she’s found that face-analyzing AI works significantly better for white faces than Black faces.

She tested software from Microsoft, IBM, and the Chinese company Megvii to see how well each of their face-scanning systems did at figuring out whether a person in a picture was a man or a woman—a task all three are supposed to be able to perform. 

If the person in the photo was a white man, her study found, the systems guessed correctly more than 99 percent of the time. For black women, though, the systems messed up between 20 and 34 percent of the time—which, if you consider that guessing at random would mean being right 50 percent of the time, means they came close to not working at all.

Google famously misidentified pics of Africans with gorillas. (Note: the pic to the left IS a real gorilla). No one wants to offend dark-skinned people, so they developed a program to automatically change the skin color in photographs. The European כוסית girl you may be considering on a dating site may well be in reality a Zulu or Andamanese. Not that this is bad, but if they start manipulating the appearance of people on the internet, they may end up giving clear blue eyes or yellow hair to everybody. Fat will be slimmed down and short people will become taller. And so on. 

Alternatively, Nordic persons will be changed into Africans, like President Donald Trump who was shown with strange orange skin in the media. Or healthy people will be given the appearance of sickness, like recent pics of Vladimir Putin.  But illusion will not make us free.
