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". https://t.co/WGoO92MYiM

[Manoel @manoelribeiro]

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

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/🧵⬇️ https://t.co/PMcabTrWI2

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. https://t.co/EupwDMBdnz

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. https://t.co/xEcpjPrNYO

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 https://t.co/vmnCQVSohg [1/]

@RondaLoPsych That’s 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: https://t.co/p6x14RImXL

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

[Justin Cheng @jcccf]

@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.

@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: https://t.co/RitxeEr4Kw

@srijankedia Here's the research track schedule, and I think a video will be up later: https://t.co/ho7wMfrNOh

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 https://t.co/KBBM4E9qwL

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 https://t.co/CUygBTEZ0T

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

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
