@julian @msbernst I think in practice, the small increase in upfront nerves caused by the push to post was short-lived. Because commit offered a warrant/justification for posting, people felt more comfortable in the act of posting and had the expectation of being supported/responded to by the rest of the group.

@julian @msbernst that’s a fair concern! We tried to address this in a few ways: first, there’s no punishment for not fulfilling a commitment. We have stronger messaging about remembering to commit versus fulfilling, and there’s an understanding that people might not have the ability or inclination to post always. It served more as a push to actually go through with sending something when people already had the inclination.

This paper argues that online spaces become ghost towns because it's too easy to lurk without contributing, and that asking people to regularly re-commit—or the incoming messages start getting muted—reverses the trend. arxiv.org/abs/2410.23267

(7/7) Why would this matter? Small-group interactions are beneficial to users' mental health and wellbeing, by providing opportunities for social support and relationship-building. However, these groups often struggle to reach a sustainable activity level, where Commit can help.

(6/7) Participants treated sustaining the conversation as a shared responsibility of the group. Commitment served as an excuse for messaging, lowering the social risk. These effects then compounded, since one user participating lowered the threshold for others to join in.

A diagram explains how commitment affects participation: when someone commits, they announce their intention to participate. This commitment leads to three things (indicated by arrows): social assurance (knowing that other members who have also committed will probably post), goal-setting (that is accompanied by obligation), and a warrant to post (having committed justifies following through). These three factors lead to (indicated by an arrow) an increase in participation, which leads to a norm of participation (the group is more active). The norm of participation feeds back into increased participation (shown by an arrow).

(5/7) We found that Commit participants *doubled* their messaging activity without compromising quality. In fact, Commit participants had more interesting & deep conversations, growing closer with each other during the study. How did Commit achieve this effect?

(4/7) We then ran an evaluation with 57 participants in 12 groups (split between Commit and a control condition) interacting for three weeks. The control condition employed similar notification and banner reminders, but without messaging around commitment.

(3/7) We built Commit: a smartphone group messaging app built around the commitment mechanism. In Commit, people commit to messaging the group at least once every two days. Users are reminded to fulfill and renew their commitment with notifications and in-app banners.

A screenshot of the chat within a group called students-msg with 4 members. two banners are at the top of the screen. The first is a pale red and reads "your commitment ends in only 8 hours! Press here to commit ahead for next cycle." The one below states "You have 8 hours left to fulfill your commitment." Messages are interspersed in the chat with small announcements that different members have committed to posting.

(2/7) Our design asks group members to “commit”: explicitly promise to participate in discussion on a regular basis. Committing is a condition of membership: there is no "social loafing" option.

A state diagram of how the commit mechanism cycle works: a user starts out as uncommitted, unable to read messages or participate in the group. they can click a button to commit to participating, and therefore join the committed state, where they can see all messages in the group and participate. In the committed state, users can recommit to stay in that state at the end of the cycle, or do nothing to fall back into uncommitted.

Have you ever worried that no one would respond to your message? Our #CSCW2024 paper proposes a commitment-based design in online groups to address this: arxiv.org/abs/2410.23267 🧵

Three texts from the same person. The first reads "Do you have advice on what I should put I the thread promoting commit on twitter?" The second reads "I could use some help." After those texts is the read receipt. A third, unread, message follows "Guys????"

"A 91-year-old man honored by Israel for saving a Jewish life during the Nazi Holocaust has returned his medal in protest of the Gaza assault. Henk Zanoli was given Israel’s Righteous Among the Nations award for his actions under Nazi occupation in Amsterdam. In 1943, Zanoli smuggled out a Jewish boy and helped hide him in his home for two years, despite Nazi suspicion he and his family backed the resistance.

Let's talk about the "Weaponization of Government". As a researcher of disinformation, it's been both frustrating and enlightening to become the target of disinformation. The old playbooks for how to respond to this stuff (often advocating strategic silence) are broken. But we're just figuring out how to fight back. Here's my statement detailing how the House Judiciary Committee mischaracterized my voluntary service on an advisory committee to weave a false narrative: cip.uw.edu/2023/08/23/starbird

The House Judiciary Committee's interim report effectively punishes an academic researcher (and others) for volunteering to serve on an advisory committee — to try to help our country become more resilient to rumors, misinformation, and disinformation about elections. While they claim to be supporting "free speech", the report and related efforts function to chill speech — demotivating researchers like me from sharing what we know with government and social media platforms.

I have a new paper! Together with r/worldnews on Reddit, I show how collective, good-faith human collaboration can steer algorithms to reduce the spread of unreliable news without needing to understand the underlying code.

The big challenge of this paper was to convince scientists that the question was worth asking at all — which took me SIX years.

Publishing the article required me to create a Rosetta stone for socio-technical science of human-algorithm behavior.

Visit days for PhD Admissions are coming up!

I'm one of the co-chairs for Stanford's Admit Weekend and we're hoping to institute a code of conduct this year.

Does your institution already do this? We're planning to take some inspiration from CSCW's, but I'd be interested in seeing any specific to the context of visiting, admitted students.

Advice, resources, and boosts are welcome!

Despite the promise of AIs improving human decision making, a frustratingly resilient research result has found that people with AI decision-making aids are no better than people alone or AIs alone. Why? Overreliance: we go along with the AI's recommendations even when we shouldn't. Even when explainable AIs try to make it clear when the AI is wrong!
