One day I realized that when people think something is good, what they really mean could be “it feels familiar to me”. This has changed how I view the world and how I view myself completely.
This tweet sums up EXACTLY why academia has a such huge diversity problem.
Who decides what’s a “boring research program,” a “poor pub record,” or a “higher-tier” PhD program?
It’s profs like this: a U Chicago prof with an MIT PhD & Yale BA…

Dark patterns are another issue. By default, ChatGPT users allow OpenAI to use their data for model training, exposing them to memorization risks. The opt-out interfaces unnecessarily link privacy with reduced functionality, and the more flexible control is hard to find and use.

Although people keep saying this, the fact is papers with negative results are just much harder to get published :( What if we have a conference/track dedicated for failed studies? (just some random crazy idea...)
Finally, let's work on sharing our informal knowledge more widely—such as by writing up negative results—and incentivizing people to do so. That would make much of the advice in this thread redundant (like the importance of networking), which would be a good thing!

We interviewed 19 LLM-based conversational agent (CA) users, many of whom were pessimistic about having both utility and privacy. Yet nearly all took privacy-protective measures, e.g., censor/falsify sensitive info, sanitize inputs copied from elsewhere, and seek general advice

Virginia's contact-tracing app
#COVIDwise
verifies COVID-19 positive cases using a six-digit unique PIN to prevent false reporting.
However, if all VA's 100k confirmed cases have a unique PIN, then there's 1/10 chance of collision just by input random numbers. 🤦♀️

On another note, LLM enhances human abilities, but its use raises privacy concerns. We found users fear being discovered using AI, worrying that others will question their abilities.

The "Sparks of AGI" paper shows how
#gpt4
can detect PII better than an open-source tool custom built for this task, but you have to trust OpenAI and share the data with them first to remove the PII data, isn't that missing the whole point of PII detection?

Analyzing real-world ChatGPT conversations from the ShareGPT dataset, we found users disclose PII and personal experiences, not only of their own but also of others. The use of interactive prompt strategies led to a gradual increase in disclosure, sometimes prompted by ChatGPT

A key challenge in developer-driven solutions is verifying the accuracy of information provided by developers. Past studies found errors in privacy labels created by developers, so how can we ensure that the reasons given for using APIs match how the data is actually used?

Privacy laws/platform policies have created more incentives for developers to talk about privacy (see my recent work at CSCW), but the discussion is still at a superficial level. The knowledge gap is just too big.

Interesting question 🤔 I could think of papers that study s&p concerns/strategies of these ppl but not much about novel systems/tools…the first thing that came to mind is the iOS 16 safety check feature… curious to learn more from ppl more knowledgeable about this field
I'm looking for papers that introduce a novel system/tool that is meant to make some component of cybersecurity and/or digital privacy easier for *specific* under-served, ability-diverse, vulnerable, marginalized, and/or high-risk populations...
Pointers?
