This looks really bad. It appears Twitter's photo preview algorithm focuses on the white man's face over the Black man's face despite their placement on the photos.

This is what algorithmic bias looks like. https://twitter.com/NotAFile/status/1307337294249103361

And for everyone to check against, this is the preview I currently get:

@Jack talks a lot about needing to address racial inequalities and matters of social justice. These examples seem like there is a pretty clear issue that needs to be fixed at Twitter.

Here's a 2018 blog post in which Twitter explains how its algo crops images: "The basic idea is to use these predictions to center a crop around the most interesting region."

This is by no means scientific so there may be other possible explanations, but the anecdotal evidence here isn't great.

I don't understand why Twitter doesn't allow users to select what part of the photo they want to show in a preview? This would eliminate an algo decision.
