Twitter Dumps It’s Biased Photo Cropping Algorithm That Favors White Males

  • Twitter decided to scrap its automated image-cropping system after its review found bias in the algorithm controlling the function.
  • It found the algorithm delivered “unequal treatment based on demographic differences” with whites and males favored over Blacks and females, and “objectification” bias that focused on a woman’s chest or legs, described as “male gaze.”
  • “One of our conclusions is that not everything on Twitter is a good candidate for an algorithm, and in this case, how to crop an image is a decision best made by people.”

“Twitter said Wednesday it was scrapping an automated image-cropping system after its review found bias in the algorithm controlling the function.

The messaging platform said it found the algorithm delivered “unequal treatment based on demographic differences” with whites and males favored over Blacks and females, and “objectification” bias that focused on a woman’s chest or legs, described as “male gaze.”

The news comes a month after Twitter said it was launching an algorithmic fairness initiative as part of an effort to reduce bias on its platform introduced by automation.

Twitter in 2018 introduced a so-called saliency algorithm to crop images, aiming to improve consistency in the size of photos in one’s timeline and to focus on their most important elements.

Rumman Chowdhury, head of Twitter’s software engineering and a specialist in ethics and artificial intelligence, said the company determined after its review that it is preferable to leave the cropping decisions to users.

“We considered the tradeoffs between the speed and consistency of automated cropping with the potential risks we saw in this research,” she said in a blog post.

“One of our conclusions is that not everything on Twitter is a good candidate for an algorithm, and in this case, how to crop an image is a decision best made by people…”
