The largest study ever carried out on social media deactivation has found that disconnecting lowers users political participation and also their propensity to believe misinformation
Lemmy isn't really an echo chamber. It's like saying going over to a friends place is an echo chamber because you and your friend get along. There's nothing wrong with hanging out with people who share your values and beliefs.
The problem with social media are their algorithms. They aren't designed to connect you with like-minded people, but to keep you engaged. The content that keeps people engaged tends to be terrible content.
The recent "a man or a bear" trend is a perfect example. Algorithms love divisive content like that because it drives engagement, but it also leads to people getting really upset over nothing. Lemmy doesn't have any algorithms driving engagement so it doesn't have that problem.
Lemmy’s a lot better than Reddit for not being an echo chamber because the communities are less interest specific, and most of us are here because we’re the type to seek out a better discussion rather than stick with status quo.
But as it gets bigger and the communities become more niché it will become a bigger issue.
I don't think lemmy is necessarily an echochamber per se, rather its just a place where misinformation exists and opinions are manipulated.
Lemmy does use algorithms to show you the most engaging content, and there are absolutely bots and bad actors manipulating which content is prioritised.
The genocide Joe / vote abstinence thing was a very clear example.
... That's not an echo chamber though. That's propaganda and vote manipulation mostly by literal state actors and brainwashed rubes.
An echo chamber is when people literally self segregate enough to the point that they no longer consume almost any media that doesn't fit their belief. Its exacerbated by large corporations who profit from ad revenue driven through user engagement.
Lemmy is not an echo chamber no more than the literal radio.
Reddit is not an echo chamber.
You can make these an echo chamber through varying degrees of ease. But places like Facebook, YouTube, and Twitter have been proven to drive you into one by exploiting ragebait for clicks.
You can say they're both fruit, sure. But one is like eating cantaloupe and the other like eating bananas laced with speed.
Lemmy is definitely an echo chamber, but I agree that it's not necessarily a bad thing as long as we recognize it for what it is.
There are a large number of people out there that have very different opinions than the majority of users on this platform, we need to keep things respectful even in our disagreements with them instead of tearing them down for their opinions.
