Algorithmic Justice League — research-impact: Over 70 AI researchers publicly signed letter defending AJL's research following Amazon's challenge to the Gender Shades findings on their Rekognition system

Note: While the source text confirms that the Gender Shades paper exists and was co-authored by Joy Buolamwini and Timnit Gebru, and mentions it 'put Amazon on its toes,' it does not provide the specific claim being verified: that 'over 70 AI researchers publicly signed letter defending AJL's research following Amazon's challenge.' The source vaguely references 'support from hundreds of other researchers' but does not specify a letter, the number 70, or the temporal context of 'as of 2019.' The specific data point about the letter and the exact number of signatories is not addressed in the provided source text.

Note: The source text confirms that the Gender Shades paper exists and that it involved Amazon, but it does not address the specific claim about 70+ researchers publicly signing a letter defending AJL's research in response to Amazon's challenge. The source is from AJL's own website and focuses on their mission, origins, and general accomplishments, but does not provide details about the specific research-impact metric claimed (the number of researchers who signed a defense letter as of 2019). This specific data point is not mentioned in the provided source text.
