“Hey Google, give me three concrete examples of fair bias.”
Most AI/ML/Statistics procedures use Occam's razor: prefer the simplest explanation of the data. That's a bias (toward simpler explanations), but not "unfair" to anyone.
We can trust google will try to build tools that are effective for googles buisness goals without it being proclaimed in a statement of principles.
