  • Really bad headline. The actual article is about a study showing that browser fingerprinting is being used in real time in pricing target ads to your browser.

    To investigate whether websites are using fingerprinting data to track people, the researchers had to go beyond simply scanning websites for the presence of fingerprinting code. They developed a measurement framework called FPTrace, which assesses fingerprinting-based user tracking by analyzing how ad systems respond to changes in browser fingerprints. This approach is based on the insight that if browser fingerprinting influences tracking, altering fingerprints should affect advertiser bidding — where ad space is sold in real time based on the profile of the person viewing the website — and HTTP records — records of communication between a server and a browser.

    “This kind of analysis lets us go beyond the surface,” said co-author Jimmy Dani, Saxena’s doctoral student. “We were able to detect not just the presence of fingerprinting, but whether it was being used to identify and target users — which is much harder to prove.”

    The researchers found that tracking occurred even when users cleared or deleted cookies. The results showed notable differences in bid values and a decrease in HTTP records and syncing events when fingerprints were changed, suggesting an impact on targeting and tracking.

    Additionally, some of these sites linked fingerprinting behavior to backend bidding processes — meaning fingerprint-based profiles were being used in real time, likely to tailor responses to users or pass along identifiers to third parties.










  • In that sense, Westgate explains, the bot dialogues are not unlike talk therapy, “which we know to be quite effective at helping people reframe their stories.” Critically, though, AI, “unlike a therapist, does not have the person’s best interests in mind, or a moral grounding or compass in what a ‘good story’ looks like,” she says. “A good therapist would not encourage a client to make sense of difficulties in their life by encouraging them to believe they have supernatural powers. Instead, they try to steer clients away from unhealthy narratives, and toward healthier ones. ChatGPT has no such constraints or concerns.”

    This is a rather terrifying take. Particularly when combined with the earlier passage about the man who claimed that “AI helped him recover a repressed memory of a babysitter trying to drown him as a toddler.” Therapists have to be very careful because human memory is very plastic. It’s very easy to alter a memory, in fact, every time you remember something, you alter it just a little bit. Under questioning by an authority figure, such as a therapist or a policeman if you were a witness to a crime, these alterations can be dramatic. This was a really big problem in the '80s and '90s.

    Kaitlin Luna: Can you take us back to the early 1990s and you talk about the memory wars, so what was that time like and what was happening?

    Elizabeth Loftus: Oh gee, well in the 1990s and even in maybe the late 80s we began to see an altogether more extreme kind of memory problem. Some patients were going into therapy maybe they had anxiety, or maybe they had an eating disorder, maybe they were depressed, and they would end up with a therapist who said something like well many people I’ve seen with your symptoms were sexually abused as a child. And they would begin these activities that would lead these patients to start to think they remembered years of brutalization that they had allegedly banished into the unconscious until this therapy made them aware of it. And in many instances these people sued their parents or got their former neighbors or doctors or teachers whatever prosecuted based on these claims of repressed memory. So the wars were really about whether people can take years of brutalization, banish it into the unconscious, be completely unaware that these things happen and then reliably recover all this information later, and that was what was so controversial and disputed.

    Kaitlin Luna: And your work essentially refuted that, that it’s not necessarily possible or maybe brought up to light that this isn’t so.

    Elizabeth Loftus: My work actually provided an alternative explanation. Where could these merit reports be coming from if this didn’t happen? So my work showed that you could plant very rich, detailed false memories in the minds of people. It didn’t mean that repressed memories did not exist, and repressed memories could still exist and false memories could still exist. But there really wasn’t any strong credible scientific support for this idea of massive repression, and yet so many families were destroyed by this, what I would say unsupported, claim.

    The idea that ChatBots are not only capable of this, but that they are currently manipulating people into believing they have recovered repressed memories of brutalization is actually at least as terrifying to me as it convincing people that they are holy prophets.
