- The study compares over 100 million content pieces across platforms like Gab, Facebook, Reddit, and Twitter to understand how their interaction patterns and algorithms influence information spreading and echo chamber formation.
- Results indicate that Facebook and Twitter have strong homophilic clusters, leading to more segregated news consumption compared to Reddit.

@ZubyMusic @IAmAaronWill I don’t dislike you, I think you are being manipulated. The University of Oslo wrote an article called The echo chamber effect on social media. You should read it. The use of labels to divide people into goods and turds has historically been a precursor to conquering them.
@Brian247478847 @Polymarket When you maga morons use these social media polls, you realize all it takes is for a few retweets from big maga users to completely skew the results? Its not scientific…its a demonstration of the echo chamber effect on social media. But you’re maga, so you “did your research”
@MikeHudema Anyway, our analyst said that the issue of #climatechange is becoming more polarized due to the “echo chamber” effect on social media. This means that people are only exposed to one point of view, which often denies the existence of climate change, and they are immune to

@Missus_Massacre Thank you for sharing your perspective, it's refreshing to see someone who values authenticity and avoids the echo chamber effect on social media.
@allomatey Right, I definitely saw those (sadly still do on occasions) it's annoying even though they are obviously nonsense & even more when others believe it blindly. The echo chamber effect on social media doesn't help & is probably bigger given how popular the show has got over time.

As social media companies provide great amount of information and content, it slowly feed their algorithm to suit their users preferences forming polarized groups and when more polarized group are created the faster misinformation spreads. https://t.co/3vsAxQSaDB

@pettertornberg Wow! I (and co-authors) consistently find the opposite https://t.co/IoaALWr3BZ It'd be nice to understand why we consistently find different results :)
Social media algorithms perpetuate echo chambers by showing users content that aligns with their existing beliefs, further entrenching existing biases and preventing exposure to diverse perspectives. https://t.co/lNTZBL2NGG #eme4390S23

@micsolana @CHSommers 2/Two, given there's the echo chamber effect on social media, that is, people with the same problem clustering together and commiserating together, I imagine that exposure to other people's pain and pathologies can make one's own mental health worse.
@mynerdyhome But it's been proven that it's the "Engagement Algorithms" heavily used in Social media. Done to get users to keep using it and end up funnelling people into ever increasing Apocalyptic death spirals of echo-chambers. Thus creating extremism on both sides. https://t.co/WOsvA28zrT

Social media works like that, but with *people* rather than ideas. It puts us into little echo chambers with people who see the world like we do - and we start to imagine everyone (or everyone *sensible*) sees the world just like us. https://t.co/FlC9eKzsVv
