This is facebook. They've been caught recording people and selling that for advertising, they deny it because technically your audio is transcripted not recorded and they can send only some keywords back so whole conversations aren't sent back to them.

I think you partly may just be biased by happening to notice ads more if they fit the topic you sent to your wife or being lenient in deciding if ads meet the categorization. And if you dwell on an ad because it seems to match, you may get more similar ads. Here is how I think you could design a more robust (but less fun) experiment: - Come up with a bunch of topics, write them down on slips of paper, put the paper i…

There will be some bias in what they choose to screenshot right? Meaning, the unrelated topic might show up in the feed but they don’t screenshot it because it doesn’t fit the narrative?

Also, what we’re interested is if the text changed what was shown. If I saw ads for X last week but didn’t notice them, then spoke to a friend and noticed them and took a screenshot, it would appear to confirm the theory. Even though I was always seeing ads for X.

Ultimately, I don’t think people who are convinced of this theory will change their minds so it’s a moot point.

Assuming you're using a phone, is there a "keyboard app" that could be intercepting things before WhatsApp? other endpoint issues with security? Not that I'd be surprised to see a big company flatly lying about their product, but because they're so big I suspect you need to work hard to eliminate other possibilities before taking them to court.

No keyboard app. We use the regular Android Keyboard provided by Google.

so it's clear, your gboard si harvesting all input you type and then sells these data to highest bidder, nothing to do with whatsapp, just good old Google harvesting everything for ads

Whatsapp FAQ: WhatsApp's end-to-end encryption is used when you chat with another person using WhatsApp Messenger. End-to-end encryption ensures only you and the person you're communicating with can read or listen to what is sent, and nobody in between, not even WhatsApp. This is because with end-to-end encryption, your messages are secured with a lock, and only the recipient and you have the special key needed to un…

Can I not train a text classifier on encrypted text? Basically, let the AI figure out what ads get clicked the most for a given string of encrypted 24h window of chat history. Eventually, the AI is going to hit on its “Rosetta Stone”, even without ever formally decrypting the text, much less any human reading it. With millions of conversations happening on WhatsApp, why shouldn’t that be possible? And it’s not even a…

It doesn't matter how many conversations are going. With private key encryption, what a phrase encrypts to for one person would be different than the next. It would have to be trained solely on your conversation. Encryption is also dependent on all the text before it as well as text in the same block, so it would have to be the beginning of the message with no metadata to throw off alignment saying the 16-byte phrase so many times that it could pick up a difference. I'm pretty confident it's impossible to get anything useful out of that.

This may or may not apply to the anecdote you shared about your wife, but since these apps know your relative proximal location to your weak/strong social connections, they also can know what your friends may search for and is often-used flavor of targeting. e.g. You and a bunch of friends go to dinner and have a conversation about , at least one of those friends googles something about that topic. You later see an a…

I thought of this. Just to be clear, neither she nor I did any searching on diabetes or anything like that. I can understand this being driven by search, chats, emails, etc. (basically any type of keyboard input). But here, the mode of communication was voice-only.

Yea I've definitely had situations where I've been challenged in this way (in which I definitely was having a voice-only conversation that seemed to be targeted after the fact). It can be vexing.

It was mentioned elsewhere in this thread, but this is where Baader Meinhof may apply. I don't how many times I've seen a targeted ad that was a "miss" in terms of recency bias. But I absolutely remember every time there was a "hit".

Both situations were targeted based on my digital behavior, but they're playing the volume shooter game. Taking as many shots as possible hoping eventually they score. This could be true in your case. The fact that you and your wife were having a recurring conversation about stem cell research, diabetes, etc. suggests that its likely that this is in your digital fingerprint at least once in the past (recent or otherwise).

Something I try to do now, when I'm being mindful about it, is note how often I see ads that are definitely in my interest bucket but are completely uncorrelated with any recent conversations I've had. That helps at least establish an anecdotal ratio of hits-to-misses that makes the Orwellian/dystopian much less reasonable on balance.

So if were walking past a playing blaring the piña colada song, I’d see ads for alcohol and umbrellas? If coworkers around me are talking about activities I’m not interested in, I’d see ads for those?

They have far better information that shows I’m not interested in alcohol or extreme sports. Audio in the background is so low-signal that it isn’t worth showing ads based on it.

Even just transcribing speech something accurately is not something that was possible until the last couple of years. Yet this conspiracy theory has been around for a decade or more.

Occam's razor, in this situation, is that the corporate entity who profits from collected data while deceiving it's product into perceiving itself as a "customer" might, in fact be... collecting data from its product to sell to it's customers.

The core tenet of the principle is that the more entities you have to posit in any given postulate, the more assumptions you have to make, the less likely it is to be true.

I was making the point that I have to assume much less to make the statement that companies are not passively recording, tokenizing, and analyzing every conversation users have without their consent.

We did an experiment. We talked about how hard it is to find highlighter yellow nail polish. Nobody in the house is a purchaser of nail polish nor did we do any searches for highlighter or yellow or nail or polish. A day or two later my wife got an Instagram ad for highlighter yellow nail polish. It could have been a coincidence or maybe they were listening.

Or maybe some combination of things we did previously led naturally to thinking about that yellow nail polish. I'm thinking about something like the trick where you ask somebody a bunch of addition problems that have 14 as the answer (what's 10+4? 2+12? 3+9? etc...) then ask them to name a vegetable and they will almost always say carrot.

This isn’t evidence. Even if Facebook was not listening to your conversations, there would be some rate in which you would just randomly be served an ad related to a topic you were discussing. There needs to be evidence that it is happening at a rate too high to be attributable to chance.
