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.

6 Steps to Selling on Social Media Messaging Platforms

Have you ever heard of conversion conversations? This sales technique involves getting to know your prospect through an online messaging platform, creating a conversation, then shifting to a sale once they are qualified. The best part? It is entirely free if you do the legwork.

When choosing which social media platform to use for your messaging, keep in mind that Facebook is still the largest social media platform, used by 2.6 billion users, according to Statista. Pew Research found that 75 percent of high earners use Facebook. Instagram is more visual, so if you are selling products or services that look good in photos, or if you are targeting younger generations, go for Instagram. According to Statista, 32 percent of users are between 18 and 24, and 33 percent are between 25 and 34.
