how would you prove the inverse of this? i.e cambridge analytics didn't have any material impact.

I think most are basing it on the assumption that CA with the help of Facebook could target millions of americans in a personalized way and display ads that would nudge them to a certain political candidate.

No way to say it's a guaranteed method, but it's as effective as bill board marketers proving their ads change people's opinions about a brand.

That's where most of the presential election fund raises go to anyway right? to reach out to people and sway their opinion?

I don't know, but that alone isn't a convincing argument.

Perhaps. The question is, what is the effect? I would wager it is very small to nil.

As nil as Coca-Cola’s billboard/tv marketing ? When I still had FB, their ads/propaganda was super convincing about Hillary and her hacked email server yada yada.

It was quite a genius marketing method to reach millions.
