Here's a blog post summarizing @manoelribeiro's research on post approvals in online communities! To paraphrase a key takeaway, "post approvals creates communities centered around fewer, higher-quality posts". research.facebook.com/blog/2022/7/po…

In our latest @icwsm paper, we study how proactive moderation impacts groups on Facebook. We do so by studying a feature called "Post Approvals," popular among groups that seek to ensure a high standard of quality for all their posts 🧵arxiv.org/abs/2205.03258

Our paper is out in @PNASNews (w/ @andyguess, C. Tarnita): Using a model & Twitter data, we show that polarized news coverage can lead people to unwittingly sort their social networks along political lines, even w/o knowing their friends' politics! 1/🧵⬇️ pnas.org/content/118/50…

Awesome new paper from some of my favorite researchers. They designed a very nice experiment and this punchline is 💯: Dealing with a biased sample is challenging for statistical models AND mental models of the world. journal.sjdm.org/21/210225/jdm2…

From May to October 2020, people around the world were less likely to take precautions over time.

How did COVID-19 precaution-taking change over time? We wrote a blog post detailing some findings. research.fb.com/blog/2021/02/w…

How does social comparison on social media vary by country? research.fb.com/blog/2020/10/f… #CSCW2020

What does it mean to make causal inferences about conversational behaviours? Why does that matter, why's it difficult, what would it take to get there? My #CSCW2020 paper w/ @m_sendhil & @Cristian_DNM takes a step towards addressing these questions bit.ly/2FbwwOv [1/]

@RondaLoPsych That’s right!

@jcccf thanks for the reply! i suppose if i apply and someone looks at my application and contacts me that could be something further discussed, is that right?

If you’re interested in working on computational social science problems at FB in 2021, I’m looking for interns! Also happy to chat about any questions you have! More info: facebook.com/careers/jobs/3…

@mahajan_khyati Hey! Happy to answer questions over email if you have any.

@jcccf I applied for this probably a week ago! Would love to chat more about everything the internship would entail!

@RondaLoPsych Hey, and thanks for the interest! I’m not super familiar with this, but immigration-related questions would probably be best discussed with your potential recruiter who would know more.

@jcccf Is it possible for FB to sponsor a work visa for international applicants? Speaking as an interested Canadian PhD here :)

@kornraphop Projects usually get decided closer to the start date, usually I’ll spend some time discussing what the student would like to work on. As an example, here’s a recent paper from a past intern: research.fb.com/publications/d…

@jcccf Do you have any project descriptions in particular? What kind of projects that we could contribute on within the short period of time as an intern?

@srijankedia Here's the research track schedule, and I think a video will be up later: www2020.citi.sinica.edu.tw/schedule/resea…

@jcccf Looks interesting! When is the presentation?

When do misperceptions happen in online conversations? (with Jonathan Chang & Cristian Danescu-Niculescu-Mizil) research.fb.com/blog/2020/04/h…

Research on @GamesDoneQuick by Stephen Tsing-Han Sher suggests that featuring “the couch” on stream helps create a virtual living room that viewers can be a part of. #CSCW2019 static1.squarespace.com/static/5b18aa0…

A large-scale analysis of dark patterns on shopping websites found that (1) 40% of countdown timers don’t actually matter (2) 9% of uses of social proof (e.g., “N people bought X in the past hour”) are false. Work by @AruneshMathur at #CSCW2019 webtransparency.cs.princeton.edu/dark-patterns/

Algorithm-in-the-loop decision making should be accurate, reliable, and fair. But people don’t do the last two: they don’t rely more on an algorithm even if it’s more accurate, and rely on their own judgment more when evaluating some groups of people. @benzevgreen at #cscw2019

Many factors to consider when designing interventions for reducing political polarization (e.g., if an interface seems to question a person’s competency). By @matnel at #cscw2019 tuhat.helsinki.fi/ws/portalfiles…

On Github and Wikipedia, larger teams produce more work per team member. (Have/can these observations be replicated in an RCT?) Work by @goranmuric, @aabeliuk, @KristinaLerman, @emilio__ferrara #CSCW2019
