On some it is, and some it isn't.
> It's a crucial practice for advertisers and marketing teams that dives deep into researching the psychological response towards images, text and dozens of other variables. Human subjects are acting as lab rats in order to extract some data points to drive the next test and campaign.
This is just a long and emotionally laden way of saying "changing images and text to see which works best".
> So, yes, it should definitely require informed consent and opting in.
Guess we're just going to have to agree to disagree then. I don't see any reason whatsoever to think that this practice is harmful to the subjects being experimented on.
At worst, it's harmful to society in general because it incentivizes consumerism and potentially self destructive behavior. But that is completely orthogonal to the issue of informed consent. If you got perfectly informed consent from 10,000 people to tease out the perfect pitch text, and then deployed it against the rest of the population, the effect would be exactly the same, whether or not you got consent.
