How can we make social media a healthier platform for health information?

Misjudging information can spiral out of control in hours. Researchers at the Harvard Kennedy School highlight that misinformation is a major threat to global public health(opens in a new tab), especially when there is a large lag between the emergence of a disease and an effective solution. Examining COVID-19, they identified that the lag time for vaccine development has created a vacuum for scepticism to grow and misinformation to spread – which has been amplified by bots and trolls.

Social media is designed to share information we believe to be correct, quickly, and works on gut-based intuitions where patterns are rapidly recognised, and biases quickly confirmed.

Misinformation is having a serious impact on our health worldwide.

News providers are reaching more readers via social channels, which can get overwhelming at times. If you are an RSS feeds lover, like many others on the GT team, there are a few worthy RSS Feed reader apps for iPhone.

This Documentary Will Make You Deactivate Your Social Media

If you are reading this article, chances are you found it through social media. And that means the platform that used it to get your attention knows you are here. While you are reading these words, Facebook, Twitter, or Google are likely reading you.

That is the premise of the new Netflix documentary The Social Dilemma from filmmaker Jeff Orlowski, which features repentant Silicon Valley figures sounding the alarm that big tech companies are doing three very dangerous things: (1) Spying on you. (2) Manipulating your feeds to keep you engaged. (3) Deepening your biases and blind spots by pushing away everything else.

Twitters CEO thinks that social media platforms can be addictive, while Facebooks CEO does not agree with him

During a hearing before the Senate Judiciary Committee, a discussion was being held about the content moderation policies of various platforms and the impact of the recent US General Election. When Senator Lindsey Graham asked both Jack and Mark about their opinion whether their platforms can become addictive for the users, both answered differently.

As per Jack Dorsey, (like any other tech) social media platforms including Twitter and Facebook can make users addicted to continue using them. His opinion is in line with the opinions of several psychologists also who say that these social media networks give the users a sense of well-being by giving them a feeling of connection with others. One post after the other, and the urge of users to keep returning to these platforms to see newer posts one after another is like a trigger for their dopamine centers in the brain. And that is why psychologists believe that all social media platforms tend to become addicting for their users.

However, Mark Zuckerberg is of a different opinion. He stated in front of the Senate Committee that he believes that all the research regarding this matter is still inconclusive, and no one can say for sure if the social media platforms are addicting or not.

Apple complies with Censors in China and removes two RSS Feeds from their iOS App Store

It is reported today in Hong Kong that more RSS apps are disappearing from Apples App Store in China in a new crackdown on feed readers. Apple removed two additional apps that pull content from RSS feeds, allowing Chinese users to access articles that might normally be blocked by the countrys Great Firewall.

Fiery Feeds and Reeder both acknowledged on Twitter that their iOS apps had been removed in the country. They cited a 2017 tweet by Inoreader, another popular RSS service, which posted a letter from Apple saying its app was removed in China because it included content that is illegal in the country. Inoreader said the entire service was blocked in April this year.

Fashion brands should engage more proactively around sustainability on social media

Rather than using aggregated statistics and sentiment analysis, the research team used a qualitative approach to drill down into all the tweets posted around the two case studies, and divided them into key topics, positions, purpose and arguments, in order to determine how users engaged in the debate around sustainability and ethics in fashion.

They found that the two main ethics and sustainability issues raised by social media users were environmental concerns, in the first case study; and labor conditions in the supply chain, in the second. Analysis revealed that only a small proportion of tweets were explicitly critical and that those that were, were actually prompting a relatively sophisticated debate that fashion brands may benefit from engaging meaningfully with.

This Might Be What Finally Makes Me Quit Facebook in 2021

This Might Be What Finally Makes Me Quit Facebook in 2021. It is an Example of What No Company Should Ever Do.

There are a lot of reasons that might persuade someone to quit using Facebook. There are privacy concerns, data leaks, and incendiary content, not to mention the monetization of your personal data. Any one of those reasons should be enough, but most people aren't persuaded to quit Facebook. Most people just keep using it--almost three billion of them every month, in fact.

The real problem, however, is that Facebooks primary goal is to seduce you into spending more time on Facebook through a variety of different features and notifications. Then, it makes it harder and harder to find the setting to opt-out of those features, even if you have no desire to use them.

That, by the way, is my main complaint with Facebook. The company isn't trying to build features that make it better or more convenient for you to use. Instead, it's designing its product solely to make it better and more profitable for Facebook, even when that results in a worse user experience.

Facebook Has Lost its Dominance Among Key Demographics and Social Media Users

There was a time not all that long ago when Facebook was considered to be the absolute pinnacle of social media in general. Because of the fact that this is the sort of thing that could potentially end up being no longer the case without widespread innovation, Facebook has worked quite hard to diversify its offerings. However, recent data suggests that in spite of the fact that this is the case, Facebook has now lost its dominance among key demographics as well as social media users in general.

According to research conducted by the EdisonResearch, two very intriguing statistics have emerged. The first is that Facebook is no longer the social media platform of choice for people between the ages of 12 and 34. This is arguably the single most important demographic out there due to the reason that these are the people that the vast majority of advertisers are going to want to target at any given point in time. Only 21% of users between 12 and 34 years of age say that Facebook is their social media brand of choice.
