Computational social scientist. Incoming postdoc @UW CIP. When I'm not trying to whip up new recipes, I study why people fight on the internet so much.

Our paper on the misrepresentation of COVID-19 science on Twitter has just been recommended for final acceptance at #CSCW2024!

Here's an article providing a lay summary of our upcoming #cscw2024 paper! ⬇️

[ACM CSCW @ACM_CSCW]

Why was COVID-19 misinformation so rampant despite scientific evidence to the contrary? A new #CSCW2024 paper suggests a potential reason—scientific consensus was misrepresented among the public! Here’s an article summarizing the main points: https://t.co/mNiWzSV9Wi

Hey everyone! We're working with some tremendously talented high school students to learn more about soft moderation. Could you please spare 10 minutes to fill out this anonymous survey and/or repost it to your network? Thanks!

Interesting study. False balance can skew public perception of what science actually says...

"...public discussions of COVID-19 science result in vast misrepresentations of scientific consensus across several topics"

Join Anna Beers, Rod Abhari, and myself for a panel on Misrepresenting Science at Stanford University's Scientists Speak Up event on July 10th! We will discuss (mis)use of COVID-19 science during the pandemic. Register: https://t.co/mtPoK6LKw5

@PeterDaszak Thank you Peter -- I'm very glad you enjoyed the panel discussion!

[Alexandros Efstratiou @alextheEfstra]

Topic extraction on abstracts reveals several areas of research. We focus on the 4 meta-categories that receive the most attention on Twitter: vaccines, non-pharmaceutical interventions, drug treatments, and COVID-19 dangers

Content analysis of tweets also reveals tactics and motivations behind public Twitter discussions of science, e.g., attacking scientists' integrity or cherry-picking findings against the authors' advice

[Alexandros Efstratiou @alextheEfstra]

Despite pro-consensus accounts having more frequent sign-ups historically, we see a shift in this pattern about a year into the pandemic

[Alexandros Efstratiou @alextheEfstra]

This mostly happens because of very few "hyper-popular" papers

[Alexandros Efstratiou @alextheEfstra]

Comparing scientific consensus against "public" consensus, we find large discrepancies in how science is represented. Most glaring example: vaccines. Although only ~4% of vaccine papers challenge safety/efficacy, ~45% of users/tweets use these papers to challenge vaccines

[Alexandros Efstratiou @alextheEfstra]

We collect COVID-19 preprints from bioRxiv and medRxiv, then use Altmetric to collect popularity statistics and tweets mentioning these papers
