As thousands of lawsuits proceed against social media companies for alleged harm, social psychologist Jonathan Haidt lays out the seven main arguments for holding social media companies legally responsible.

In this live interview with phone-free childhood advocate Jonathan Haidt, host Ava Smithing—of Gen-Z—presses Haidt on why there isn't more of a research consensus on the mental health implications of social media for children, among other contentious topics.

Social psychologist Jonathan Haidt, author of 'The Anxious Generation,' contends that children are losing the ability to pay attention as they spend half their lives perusing social media content designed to hook them.

Our phones can provide a dopamine hit because of our positive associations with them, which feeds into what some psychologists call social media addiction.

Facebook launched its 'like' button and Twitter its 'retweet' button in 2009, innovations psychologist Jonathan Haidt argues rewired social media to reward outrage over accuracy.

Facebook's internal documents show that though the company publicly plays down Instagram's harms, its own research found that Instagram has promoted mental health issues for teens.

Social media addiction, though not a clinical diagnosis, refers to the idea that infinite scroll, notifications, and algorithms override one's ability to stop using them.

Excessive social media use is linked to feelings of increased isolation, mental health declines, increased stress and general dissatisfaction among teens.

A major dopamine hit from social media use comes from unpredictability—not knowing if the content users post or share will get the 'like' from other users, triggering cycles of anticipation similar to those experienced with a slot machine.

Social media platforms benefit not just from ensuring they have satisfied users, but also from the personal data they scoop up and can then sell to online advertisers.

American Psychological Association issues recommendations for teen social media use

Listen to this three-minute podcast to learn more about the American Psychological Association's recommendations for teenagers' use of social media. The first report of its kind, it advises parents to closely monitor teens' social feeds during early adolescence, continually screen for signs of problematic use (such as sleep interference), minimize the amount of dangerous content their child is exposed to (such as disordered eating), and limit their teen's use of social media around appearance-related content.

Safeguards that social media companies created to protect children on their platforms failed at least half the time on Snapchat, Instagram, TikTok, and YouTube, according to recent research.

Social media can reinforce echo chambers that amplify pre-existing sentiments

A 2023 Nature study showed that exposure to diverse content left participants with unchanged core beliefs, suggesting social media alone cannot create hateful viewpoints. However, such platforms allow rhetoric to spread widely, potentially exacerbating geopolitical tensions.

As of 2026, age verification systems on online platforms have included the collection of personally identifying information, such as government IDs, and biometric age checks that rely on AI-based facial recognition.

The 'Facebook papers' revealed the company prioritized profit over public safety

A whistleblower came forward with internal documents showing employees warned leadership about the company's role in fueling political unrest and misinformation. Systems like XCheck shielded high-profile users like President Donald Trump from normal content rules, often to avoid PR backlash.

Social media can be a valuable public health tool, combating misinformation, advancing health research, boosting social mobilization, and raising awareness of health services and events.

Balancing free speech while curbing misinformation has destroyed content moderation

Accusations of censorship and bias have led social media companies like Meta and X to scale back or abandon moderation tools—just as foreign propaganda surges. Researchers say their ability to track manipulation online has become severely limited.

Mark Zuckerberg said some of the details in 'The Social Network' movie were spot-on—but most of the story arcs were inaccurate.

Conspiracy theories today are often born from online radicalization

New York Times tech columnist Kevin Roose examines how individuals become radicalized while using platforms like YouTube.

Mark Zuckerberg apologized for not doing enough to stop the spread of misinformation on Facebook ahead of the 2016 election

Leading up to the 2016 election, misinformation about both Donald Trump, Hillary Clinton, and even Barack Obama flourished on Facebook. In the final stretch leading up to the election, more than one-quarter of Americans visited a fake news site supporting either Trump or Clinton. Many fake news studies have widely different methods of measuring and assessing the impact of fake news, so the actual impact it had in the 2016 election is unclear.

Facebook settled a lawsuit over Zuckerberg allegedly stealing the original idea for the company for $65M

While at Harvard, three students (Cameron Winklevoss, Tyler Winklevoss, and Divya Narendra) approached Mark Zuckerberg with the idea for a platform exclusively for Harvard students called ConnectU. Those students sued Facebook, alleging that Zuckerberg stole the idea from the trio.

The first social media platforms date back to the late 1990s, and their algorithms were typically chronological, with entities like MySpace and Facebook feeding users content from the most recent posts to the oldest.

Mark Zuckerberg credits some of Facebook's success to constant evolution

Before becoming the head of OpenAI, Sam Altman was the president of Y Combinator—a startup accelerator company that supported companies like Airbnb, DoorDash, and Coinbase. In 2016, Altman interviewed Zuckerberg about creating Facebook and its growth over time. Zuckerberg said that, unlike other companies (think: CourseMatch), Facebook kept growing and adding new features, which prevented the app from becoming obsolete.

TikTok's personalized algorithm activates the brain's reward system

A 2025 Washington Post study found that 75% of the TikTok users it studied nearly doubled their time spent on the app within a month. Experts in design and psychiatry say this is due to the app's interface and algorithm, which, after learning about the user's preferences, recommend videos more likely to activate that person's dopamine reward system than non-personalized suggestions.

Meta has added video features to attract more young users to Facebook

Amid an aging userbase and competition from newer social networks like TikTok, Facebook has seen its perceived relevance and cool factor progressively decrease. The Local tab and dating features are among several efforts to counter this perception.

Why this artist staged a satirical romance with Mark Zuckerberg

Internet performance artist Harriet Richardson is using AI and Meta's social media tools to make it appear as though she's in a serious romantic relationship with Mark Zuckerberg. While the images generate laughs, Richardson also says they're part of a larger satirical project aiming to highlight the larger societal impact of Meta's decision to discontinue fact-checking content across its platforms.

Aimed at increasing user engagement, social media algorithms will intentionally show content in feeds that is misaligned with users' beliefs because such content is more likely to be commented on.

Before 'The Facebook', Mark Zuckerberg made 'Facemash.com'

During Mark Zuckerberg's sophomore year at Harvard, he built a website that allowed users to rank and rate people's pictures from the school's online "facebooks" called Facemash.com, which quickly went viral. He was placed on academic probation for violating the school's rules around data, privacy, and computer usage. Zuckerberg says the website was a prank and he never intended for so many people to see it. FaceMash is credited with being the predecessor to Facebook.
