There was a article years ago. A young woman started getting Target coupons for diapers and baby formula. A few weeks later she found out she was pregnant. She had been using her loyalty card to make purchases and had bought unscented hand cream and some other low perfume things that apparently are usually purchased by people who are expecting as their sense of smell becomes heightened and the sents become overwhelming.
Honestly I'd like to see a ban on targeted pharmaceutical advertisement. Prescription medication should be between you and your doctor.
And then what they found was that to be more effective was to mix up the suggestions for late term pregnancy / early childhood products with basically random nonsense...
... because if its too obvious that they are highly statistically confident that they know things about you that they shouldn't, people get weirded out and are less likely to buy something so specifically targeted at them.
They know an insane amount, and they do not want you to know that they know that much.
Are we sure we can call that targeted pharmaceutical advertisement? It sounds like it could just be the algorithm accidentally discovering a correlation between expecting mothers and preference for unscented hand creams and such.
Unless Amazon did specifically program that in, I think these accidental correlation is not something you can control before it happens and trying to regulate them would be a waste of time and resources.
The other things were like a large purse/tote bag and a rug, so yeah it was kinda random (so it seems) but apparently the evidence is pretty solid in that case.
The republicans would love this technology but they're to busy trying to figure out how to turn on their TV. What's the wire thing in the back of it supposed to do? What about the little black brick with letters on it? It doesn't even say anything useful like WTF is 123? 456? 789? I get it seven ate nine! It gets this one, its funny 🤣! Anyway it will take some time before the republicans could make use of tech like that.... unless evil people help them.
