> "Facebook denies systematic bias but admits their current process allows bad actors to apply bias and takes remediating steps" If their system allows bad actors to apply bias, that's literally a systematic bias. Unless they're claiming all of their 'bad actors' are symmetrically distributed along every relevant axis[0], that's the same thing as saying that there is a systematic bias. There is no reason to believe t…
I took "systematic bias" to have similar meaning to "systematic error" meaning that there is a constant shift on every data point. Admitting the possibility of bias is very different than admitting bias in every single trending content decision.
They don't have to admit bias in every content decision. They have to admit systematic bias in content decisions in the aggregate, which does not necessarily imply bias in every content decision.
While it is technically, theoretically possible that their system is open to the introduction of these biases but does not actually exhibit those biases in the aggregate, it is astoundingly unlikely.
