Democracy depends on an informed electorate. But political issues and ballot measures can be confusing, obscuring the effects of one outcome versus another. Moreover, politics is personal. Once we make an initial decision about an issue, it can be hard to change our mind or see things from “the other side.” And talking about issues with those with whom we disagree can be challenging, especially when the conversation feels more like a debate than a discussion. Technology offers ways to alleviate these difficulties, but not without introducing problems of its own. The Internet and social media promised new ways for people to connect, discuss issues, and learn from each other. But in practice, both often inflame passions, solidify echo chambers, and spread misinformation. More recently, LLM chat interfaces may help people stay informed through personalized access to information, but mainstream chatbots tend to match user beliefs rather than clarifying or challenging them.12 Without the kind of pushback you’d encounter in a discussion between disagreeing friends, chatbots are ill-suited for helping people think through political issues in a balanced way. The goal of CivicChats is to address these shortcomings. Starting with ballot measures, CivicChats helps people better understand political issues through three different modes of discussion: a Q&A mode for understanding what a measure does and what’s at stake, an argumentative mode that presents competing views to your own, and a reflective mode that helps you examine and develop your own thinking.

Out with trolley problems, in with Reddit arxiv.org/abs/2203.16762 HMI researchers studied 100,000 posts from /r/AmITheAsshole to understand everyday moral dilemmas #icwsm2022 @icwsm @joshnguyen99 @mjeongshin @AlasdairTran, Georgie Lyall, Nicholas Carroll, @cvklein @lexing
Discussants of moral AI are likely familiar with the trolley problem that embody stark and idealized dilemmas in life-or-death situations, but what are the dilemmas in our daily lives with lower stakes and full of nuances? Our paper looks into /r/AmItheAsshole for answers. (1/n)

If you missed a few of the last 50 years of computing at ANU, we've got you covered. Prof David Hawking was here for most of them, and he spoke to us about making career choices, models of research commercialisation, team building, & more! @ANUcomputing youtube.com/watch?v=PaTDTNSa…

Two weeks ago, I had the pleasure of hosting a 'fireside chat' with the wonderful @hiyangxi and @suvsh, ANU alumni and @twitter engineers. Both have remarkable life and career stories. There's a great honesty and humility here. @lexing @charles_gretton youtu.be/TupqWj7fxtw

Artificial intelligence cannot be morally neutral, we have to decide what values we want to build into it. That's why designing Australian values into #AI systems will be the focus of a new research project launched at @ourANU today. #GrandChallenge anu.edu.au/news/all-news/mak…
