The evidence doesn’t exist because Facebook only reveals impression, not targeting data. That’s a big lack of transparency.https://twitter.com/rmack/status/1252635498205544448 …

The advertiser-supplied targeting wouldn't necessarily reveal much anyway, since much of the effective targeting happens via action prediction models + the auction

Sure, but at a minimum it would answer the question posed.

But is that a particularly informative question-answer pair?

Yes, if the point is that Facebook’s own tools facilitate the spread of harmful misinformation, at least indirectly.

But that would be true even if it doesn't happen through advertiser facing tools, but through a black box ML model + auction, no?

I think that black box ML component is potentially very important, almost completely overlooked, and would love some transparency/work on it. I keep trying to talk about it and nobody even knows much about it outside a few specialists and the industry itself.
