Twitter Web Client : In the revenge-of-the-nerds story, people with low emotional intelligence were unjustly marginalized, found refuge in the tech community (which is seen as welcoming) and used their intellect to make tech an economic & societal force, restoring their richly deserved social status.

Twitter Web Client : Viewing emotional intelligence as learnable rather than intrinsic and immutable results in a drastically different narrative than the "revenge of the nerds" narrative that's popular in tech. twitter.com/aprilwensel/st…

Twitter Web Client : Over a decade ago I began doing re-identification demonstrations. Ever since then I've been asked how data custodians can improve privacy. I'm delighted to have had a chance to help put some of my suggestions into practice. Direct link to paper: arxiv.org/pdf/1809.00103…

Twitter Web Client : PAIRs new What-If Tool lets you probe a machine learning model, no extra coding required! Visualize inference, find counterfactuals, see feature importance, try algorithmic fairness criteria. Now in TensorBoard! James Wexler Mahima Pushkarna Jimbo Wilson ai.googleblog.com/2018/09/the-wh…

Twitter Web Client : Arvind Narayanan Here's a neat little study showing how incentives impact participation. People with certain value systems are attracted to certain kinds of incentives (e.g., fixed payment vs lottery). This can lead to vastly different responses and task performance. faculty.washington.edu/garyhs/docs/hs…

Twitter Web Client : People who trust survey companies' privacy promises will have different worldviews than people who don't. So their responses to many types of questions will be statistically different from those who don't respond due to privacy concerns. This is my favorite type of sampling bias!

Twitter Web Client : Survey design is super interesting.
–The birthday thing is a way to pick a random person & avoid selection bias. I wonder if people actually comply.
–Do fewer people trust privacy promises from companies these days?
–Is the cash offer more appealing to people with lower incomes?

Twitter Web Client : Good post! But careful with "If you’re not enjoying your PhD research, you’re unlikely to enjoy a research career as a professor"

Yes, but many profs are NOT so research focused. I'm much happier now than in grad school. My PhD had few signals for that. medium.com/bucknell-hci/t… twitter.com/random_walker/…

Twitter Web Client : One last bit of trivia for this thread: Telegraph Hill in San Francisco is named for an optical telegraph that was installed there in 1850 to signal ship arrivals. This was of great interest during the Gold Rush as supplies came in by ship.

Twitter Web Client : Court finds #AI software so bad it's unconstitutional. Great work @aclu! Note that the software was judged by TESTING whether its outputs made sense, not by UNDERSTANDING its crappy code. Same can be done with ML/DNN.

Twitter Web Client : New post: Why PhD experiences are so variable and what you can do about it
freedom-to-tinker.com/2018/09/04/why…
For some people who do PhDs, it's the best time of their lives. Others regret the decision. Why is the experience so variable? How can you maximize your chance of a good experience?

Twitter Web Client : Worth mentioning here that one of the best books recounting the early history and evolution of communication and information networks, and of course the telegraph, is The Victorian Internet by Tom Standage. twitter.com/random_walker/…
