Re: Worry, our data aren't as effective as we told you
You don't even need to click on an ad, or buy anything. Advertising is clever, subliminal. The point of all this Facebook scandal is how the data (allegedly) could be used, and how clever designer advertising could be used to change opinion, or even voting habits.
That's a theory. And it's a theory that's heavily sold by online marketeers who'll offer to influence in exchange for an agreeable portion of your online budget. But quantifying the effectiveness is never easy, and investigations into this affair may shed more light on that. Did any of CA's campaign work really surgically target voter's eyeballs, and persuade them to vote (or not vote) as advertised? If it didn't, then it raises more questions about the value of online campaigning.. Or help clarify the legalities around online political campaigning, along with privacy issues for data aggregators & potential abusers.
