That's what happens when you are so bad at predicting a thing that any noise overwhelms your signal.

People sending stuff they brought back and buying something else exist, and also people buying for their friends. But if you had an actually good prediction of their behavior, you wouldn't need to proxy it by "brought a vacuum recently".

Yet, companies insist that failure is a feature, and that their local maximum is the best possible world. And will keep harming advertisers, viewers and society to keep their position at that peak.
